# Chapter 1 -- Overview of AWM

## What AWM Does

AWM is a planning/design tool for animal feeding operations that can be
used to estimate the production of manure, bedding, process water and
determine the size of storage/treatment facilities. The procedures and
calculations used in AWM are based on the USDA-NRCS Agricultural Waste
Management Field Handbook.

AWM uses the concepts of "Manure Master" to produce a gross nutrient
balance but does not track mass or concentration of nutrients for
determining land application rates or for other utilization components.

## Features of AWM

-   Provides manure characteristics for eight animal types with the
    ability to modify these characteristics and add animal types as
    necessary.

-   Accounts for bedding, wastewater, flush water and other additions to
    the waste stream.

-   Tracks liquid and solid wastes produced in multiple locations
    through multiple waste streams.

-   Develops separation, storage, and treatment components for liquid
    and solid wastes that are defined as "Management Trains".

-   Estimate precipitation and runoff entering the "Management Train"..

-   Sizes storage facilities using a defined storage period or drawdown
    dates specified by the user.

-   Develops a monthly water and waste budget for each treatment/storage
    component.

-   Provides a calculator for converting units and performing
    computations.

-   Produces a gross nutrient balance from target yields and crop
    acreage specified for crops listed in the crop database.

-   Provides a schematic drawing for each treatment/storage component.

-   Generates a standard or custom report to document the system design.

# Chapter 3 -- Navigating 

# Within AWM

## Overview

The process of designing treatment/storage facilities using AWM involves
a step-by-step sequence of screens. When developing an initial design,
the sequence of screens in the order shown on the toolbar must be
followed with the exception of the calculator that can be used within
any of the screens.

![](media/image17.png){width="6.246527777777778in"
height="0.8833333333333333in"}

The screens and their function are as follows:

[]{#_Ref11027799 .anchor}**Entering Data into AWM**

The following provides general guidance on how to enter data into the
input fields used in AWM screens:

1.  Clicking on an input cell within a screen activates the edit mode.
    The edit mode is indicated by the cursor blinking at the end of any
    value or by the text that is already in the cell.

2.  Double clicking on an input cell within a screen activates the edit
    mode and highlights the data in the cell so that it can be replaced.

3.  Using the arrow keys will exit the edit mode and move the focus
    rectangle to a new input cell.

4.  Typing any value or text in an input cell that is not in edit mode
    (cursor is not blinking and is highlighted with the focus rectangle)
    replaces whatever data is in the cell.

5.  Pressing \[Enter\] in an input cell causes the focus rectangle to
    move to the next input cell while remaining in the edit mode.

Using the above guidance for entering data into AWM input fields is
demonstrated with the following example of changing the precipitation
and evaporation values in the AWM Climate Screen.

1.  Start AWM, select a state and then press the
    ![](media/image37.png){width="0.6145833333333334in"
    height="0.2708333333333333in"} button on the **Start** screen,

> ![](media/image38.png){width="4.759722222222222in"
> height="4.415972222222222in"}\
> ![](media/image37.png){width="0.6145833333333334in"
> height="0.2708333333333333in"}

2.  Click in the January precipitation cell. This action activates the
    edit mode, and the cursor will be blinking after the value to be
    edited:

> ![](media/image39.png){width="5.929861111111111in"
> height="5.245833333333334in"}

3.  Highlight the value with the cursor and mouse or clear the cell by
    backspacing and then type in a new value followed by pressing
    \[Enter\]. This exits the edit mode and moves the focus rectangle to
    the February precipitation input cell.

4.  Pressing \[Enter\] in step 3 above allows one of two actions to be
    taken in the February precipitation input cell:

```{=html}
<!-- -->
```
a.  Type in a new value replacing whatever value is in the cell or,

b.  Press the backspace key to activate the edit mode indicated by the
    cursor blinking at the end of the value or text. This allows the
    value in the cell to be highlighted with the mouse or use the
    backspace to delete the data and then type in a new value.

```{=html}
<!-- -->
```
5.  Press \[Enter\] to go to the next cell.

6.  Steps 4 and 5 can be repeated for each cell that requires editing.

> See note next page.

# **Note:** An input cell is shaded red when the value in the cell is outside the range of reasonable values stored in the database. The values stored in the database can be edited by accessing the [T]{.underline}ools -\> Options menu. Cells shaded red is just a warning to the user that the data is outside the normal range and the data will still be used by the program for calculations.

# Although most states' rainfall and evaporation data are in the database, some information has not been updated. The Agricultural Waste Management Field Book, Chapter 10 has rainfall data for the continental United States. It can be downloaded at the NRCS website (<http://www.info.usda.gov/CED/ftp/CED/neh651-ch10.pdf>). The database for AWM will be periodically updated as information is submitted from the states.

+----------------------+-----------------------------------------------+

AWM may be started in a number of manners as explained in Chapter 2.
When AWM is opened without a specific design file it will open with the
following screen.

\`![](media/image40.png){width="4.770138888888889in"
height="4.436805555555556in"}

The illustration below shows the "New" tab selected. This is also the
default setting.

## 

## Operating Periods

AWM has two options for defining operating periods. The screen shown on
the next page will appear when the
![](media/image43.png){width="2.0208333333333335in"
height="0.2708333333333333in"} button is clicked on. Click on the radio
button ![](media/image44.png){width="1.2083333333333333in"
height="0.19791666666666666in"} for 1 operating period when the facility
is operated the entire year without variation. For example this option
would be selected for a dairy where animals are in confinement for the
entire year. Click on the radio button
![](media/image45.png){width="1.2395833333333333in"
height="0.20833333333333334in"} for 2 operating periods when a facility
operates in two distinct periods. An example of when this option would
be selected is for a dairy that keeps its animals in confinement for a
part of the year and pastures the remainder.

![](media/image46.png){width="4.478472222222222in"
height="2.5520833333333335in"}

If "2 Operating Periods" are selected, the beginning and ending month
for the first operating period must be selected. Once this period is
selected, AWM uses the remaining months for the second period. The
operating period is from the first day of the beginning month to the
last day of the ending month.

Monthly precipitation and runoff for the entire year is used in the
design of waste treatment/storage facilities regardless of the operating
period.

To continue work on a previously saved job/design, select either the
"Existing" or "Recent" tab. Selecting the "Recent" tab will show the
last ten jobs saved. Selecting the "Existing" tab will show all the
previously saved jobs in a particular directory.

[]{#ClimateScreen .anchor}The climate screen allows the user to define
the monthly precipitation and evaporation, the 25 year -- 24 hour
precipitation, and the anaerobic lagoon volatile solids loading rates.
There are two options for defining the climate data used within AWM. One
is to use the AWM database, which is the default option shown below, and
the other is to enter custom climate data for the job. Any input cell
shaded red means the data it contains is outside the range of values
stored in the data validation database. The values in the data
validation database define the range of expected values for an entry as
a check for the user. The values in the data validation database can be
edited in the [T]{.underline}ools -\> Options menu.

![](media/image50.png){width="6.134722222222222in"
height="5.436805555555556in"}

AWM has three options for accounting for precipitation and evaporation
in the design of waste treatment/storage facilities.

![](media/image51.png){width="2.9298611111111112in"
height="0.9986111111111111in"}

![](media/image52.png){width="2.15625in" height="0.17708333333333334in"}

Select this option to consider evaporation only to the extent it does
not exceed precipitation. For the example shown on the previous page,
AWM would set precipitation minus evaporation to 0 inches for the month
of July.

![](media/image53.png){width="1.9166666666666667in" height="0.1875in"}

Select this option to consider evaporation even when it will cause a
deficit value for precipitation minus evaporation. For the example shown
on the previous page, AWM would set the value of precipitation minus
evaporation to --4.7 inches for the month of July.

![](media/image54.png){width="2.1458333333333335in" height="0.1875in"}

Select this option when evaporation should be ignored. For the example
shown on the previous page, AWM would set the value of precipitation
minus evaporation to be 0.7 inches for the month of July. This may be an
appropriate option for waste storage facilities and anaerobic lagoons
where a crust will form that may impede evaporation.

If a state has supplied the data and requested it be provided in AWM,
climate data will populate the screen when the
![](media/image55.png){width="1.3020833333333333in"
height="0.19791666666666666in"} option is selected, based on the County
and Station selected from the drop-down lists. The monthly
precipitation, monthly evaporation, 25-year, 24-hour precipitation, and
the lagoon loading rate may all be edited by clicking on the associated
input cell for the data to be changed. Changes made in this manner will
only be in effect and saved for the current job. Permanent changes can
be made by clicking on [D]{.underline}ata \> Edit Climate Data on the
AWM main menu as shown below. For more on editing, see Chapter 6,
"Modifying the AWM Database."

Although most states' rainfall and evaporation data are in the database,
some information has not been updated. The Agricultural Waste Management
Field Book, Chapter 10 has rainfall data for the continental United
States. It can be downloaded at the NRCS website
(<http://www.info.usda.gov/CED/ftp/CED/neh651-ch10.pdf>). The database
for AWM will be periodically updated as information is submitted from
the states.

![](media/image56.png){width="6.246527777777778in"
height="1.0326388888888889in"}

All of the climate data populating the climate screen is cleared, as
shown below, when the
![](media/image57.png){width="2.0833333333333335in"
height="0.19791666666666666in"} option is selected. With this option the
user completes all data fields manually. The data entered in this manner
will be saved with the current job and is not available for future jobs.
To have climate data available for future jobs it is necessary to modify
the AWM database. Permanent changes to the climate database can be made
by clicking on [D]{.underline}ata \> Edit Climate Data on the AWM main
menu as shown above. For more on editing, see Chapter 6, "Modifying the
AWM Database."

[]{#AnimalsScreen .anchor}The following Animals screen appears when a
new design file is being created within AWM so a user can select animal
types and descriptions from the data file source selected on start
screen. AWM allows the user to select mixed animal types and
descriptions.

![](media/image60.png){width="6.245833333333334in"
height="2.83125in"}![](media/image61.png){width="0.9479166666666666in"

height="0.28125in"}

In most cases a single value is presented for a specific waste
characteristic. This value is presented as a reasonable value for
facility design and equipment selection for situations where site
specific data are not available. However, waste characteristics are
subject to wide variation; both greater and lesser values than those
presented can be expected. Typical or average estimates of "as excreted"
manure eventually become out-of-date due to changes in animal genetics,
performance potential, feeding program strategies, and available feeds.
Although these values are useful for long-term planning for utilization
of manure and other wastes, they should not be used in determining a
field specific application rate. Site specific waste sampling, testing,
and data collection is essential for the utilization function of an
AWMS.

Growth stage and feed rations are very important in determining manure
production characteristics. For example, once a dairy calf is over 200
pounds and on a hay ration, the calf's manure production could be better
represented by a heifer's manure production.

The following screen shows the Animals screen populated with animals
selected from the AWM NRCS data file.

![](media/image65.png){width="6.245833333333334in"

[]{#LocationsScreen .anchor}The purpose of the Locations screen is to
define where the animals deposit their manure throughout a day for each
operating period. It also establishes a manure waste stream from a
location to which waste water, flush water, and bedding are added to
form the total waste stream directed to agricultural waste management
system treatment/storage components such as a waste storage facility or
waste treatment lagoon.
![](media/image75.png){width="1.3645833333333333in" height="0.28125in"}

![](media/image76.png){width="5.353472222222222in"
height="3.176388888888889in"}

Once all the locations have been entered, the percent of manure
deposited by each animal type in each location must be entered as shown
on the screen below. Please note this is the percent of manure and not
the percent of time. Judgement based on observation will be required for
making this determination because it varies widely. The percent manure
must total 100 percent for each animal type. If two operating periods
were selected on the start screen, a location table will be presented
for each operating period.

![](media/image77.png){width="5.353472222222222in"

To delete a location first select the row by clicking on the narrow cell
just to the left of the location as shown on the screen below. This
highlights the row. Now click on the
![](media/image78.png){width="1.3645833333333333in" height="0.28125in"}
button. Rows can only be selected and deleted from the first operating
period table if more than one operating period was selected on the Start
screen. This action deletes the location from the table for both
operating periods.![](media/image78.png){width="1.3645833333333333in"

[]{#AdditionsScreen .anchor}The purpose of this screen is to
characterize the amount of flush water, wastewater, and bedding added to
the manure waste stream for each of the locations identified on the
Locations screen.

To add additional locations where waste is generated, enter the name of
the location and click

on the ![](media/image80.png){width="0.53125in" height="0.28125in"}

The total wash water and flush water in gallons per day may be entered
directly or by using the pop-up calculator. The pop-up calculator screen
is selected by pressing the
![](media/image82.png){width="0.20833333333333334in"
height="0.23958333333333334in"} button next to the Wash Water or Flush

Take care to indicate a flush volume for only those animals identified
as spending time at the location on the Locations screen. Also please
note that if recycled water is used for flushing, values entered should
only be to the extent that fresh non-recycled water is added to the
system.

Clicking on the ![](media/image85.png){width="0.8020833333333334in"
height="0.1875in"} check box will save the data in the Wash Water and
Flush Water calculator for the current design session of AWM. All values
entered into the Wash Water and Flush Water calculator will be lost once
the AWM design session is closed.

The purpose of this screen is to characterize the types and amount of
bedding used per day for each waste stream for each of the locations
identified on the Locations screen.

![](media/image86.jpeg){width="6.990972222222222in"
height="5.158333333333333in"}

**Bedding Type** -- Select the bedding type from the drop-down list. The
default bedding types included in AWM are shown below. Additional
bedding types may be entered by choosing "Data / Edit Bedding Data" from
the AWM main menu.

![](media/image87.jpeg){width="3.4895833333333335in"
height="2.6354166666666665in"}

**Eff Density** \-- The volume occupied by bedding in a manure storage
facility is reduced to account for the manure filling the void space in
the bedding over time. This is accounted for by AWM using the "effective
bedding density" in the Bedding Data table. Effective density is
affected by management style, such as the amount of time between
cleanouts. The default values can be changed by the user by overwriting
the displayed values. Eff Density values can be reset to the default
values in the Bedding Data table by clicking the [Reset Effective
Densities]{.underline} button.

**Amount \--** Click on the input cell for the bedding selected and
enter the amount of bedding added in pounds per day. If bedding is not
added every day, the amount used should be converted to an equivalent
pounds per day. If the producer knows the amount of bedding used by
volume rather than by weight, then use the LV Amt field to help you
convert volume to weight. See the example below.

**LV Amt** \-- For reference, the volume (cu ft/day) of loose bedding
added is displayed, based upon the density of the bedding set in Bedding
Data table and the amount of bedding added (lbs/day).

Use this field to assist in converting bedding amounts known by volume
into amounts by weight. For example, if a producer knows that 6 cords of
sawdust/shavings are used per month, then this will convert to (6 cords
x 128 ft^3^/cord) / 30 days = 25.6 ft^3^ per day. Then, using trial and
error, enter amounts of bedding by weight until the known volume is
displayed in the LV Amt column (a value of 270 lb/day is equivalent to
25.7 ft^3^/day).

**CV Amt** \-- For reference, the volume (cu ft/day) of compacted
bedding is displayed, based upon the effective density of the bedding
set in Bedding Data table and the amount of bedding added (lbs/day). The
compacted volume is the amount of bedding that will be used by AWM to
size the receiving facility.

The loose and effective densities of bedding can be modified by
accessing the "Data / Edit Bedding Data" from the AWM main menu. For
more on editing the AWM databases, see Chapter 6, "Modifying the AWM
Databases".

[]{#RunoffScreen .anchor}The Runoff screen estimates the contaminated
runoff that must be managed by the waste management system. Runoff
volumes estimated by AWM are conservative overestimates. Because of
this, the user is encouraged to use a method outside the program to
determine the monthly and the 25-year, 24-hour runoff volumes,
especially when larger watersheds are involved.

AWM computes runoff for two types of "watersheds:"

-   impervious "watersheds" such as roofs and frequently scraped
    concrete slabs; and

-   pervious watersheds including feedlots with a manure pack..

The runoff volume from only one drainage area for each type of watershed
is computed. If a system design requires evaluation of more than one
drainage area in one or both types of watersheds, the runoff volumes
will need to be computed outside the program and entered as demonstrated
below.

Impervious watershed runoff is computed based on a Curve Number of 98
and a user input impervious area in square feet. AWM does not allow the
Curve Number for this watershed type to be changed. If a different Curve
Number is desired, the AWM computation should be made using the pervious
watershed category or by using a method outside the program.

Pervious watershed runoff is computed on the basis of a user-input Curve
Number and watershed area in acres. Feedlots having a manure pack should
use this method. The user can enter a 1 day curve number and click the
![](media/image89.png){width="0.15625in" height="0.17708333333333334in"}
(1-day) radio button and the program will convert the 1 day curve
entered to a 30 day curve number. The 30 day curve number computed from
the 1 day curve number may be viewed by passing the mouse pointer over
the ![](media/image89.png){width="0.15625in"
height="0.17708333333333334in"} (1-day) radio button. If the user enters
a 30 day curve number and clicks on the
![](media/image89.png){width="0.15625in" height="0.17708333333333334in"}
(30-day) radio button, the program will use the curve number as entered
to compute the runoff volumes.

AWM computes runoff by first converting the 1-day Curve Number to a
30-day Curve Number using the following equation:

> CN~30~ = CN~1~ -- (CN~1~ -- ((CN1\^2.365)/631.79) - 15) log 30
>
> The equations of the EFH Handbook Chapter 2 revised for a 30 day CN
> would be:
>
> S = (1000 / CN~30~) -- 10 (Rearranged Equation 2-4)

Q = ((P -- 0.2S)\^2 / (P + 0.8S)) (Equation 2-3)

> Where: Q = runoff in inches
>
> P = rainfall in inches
>
> S = potential maximum retention after runoff begins in inches

The following illustrates the Runoff screen when
![](media/image90.png){width="2.2604166666666665in"
height="0.16666666666666666in"} radio button is selected.

height="0.17708333333333334in"}

The program will compute the runoff volumes based on the precipitation
data and runoff curve numbers entered on the Climate screen.

Runoff volumes based on calculations made outside the program may be
entered directly into the runoff table. To enter runoff volumes
directly, select the ![](media/image92.png){width="2.0729166666666665in"

[]{#MgmtTrainScreen .anchor}The purpose of the Management Train screen
is to define the sequence of management components, as described within
AWM, for each waste stream developed by the program in the Locations and
Additions screens. The sequence of components is described in AWM as
management "steps." AWM is capable of evaluating up to three management
steps or components for each waste stream. Solid-liquid separator
components split a waste stream into two waste streams -- solids and
liquids. Each of these new waste streams must be followed by appropriate
storage components. An uncovered stacking facility requires a liquid
storage component, either a pond or a tank, be specified in the next
step to store runoff. An anaerobic lagoon with external storage requires
that a liquid storage component, either a pond or a tank, be specified
in the next step. Multiple waste streams may be directed to a single
management component

The following is a blank Management Train screen for a dairy as it would
appear when AWM is run for a new waste management system design. The
waste stream column lists the waste streams from (1) locations defined
on the Locations screen, (2) any user-defined waste streams, and (3)
runoff. Clicking on an input cell will access a drop-down list of
available components as illustrated on the screen below.

![](media/image95.png){width="6.246527777777778in" height="4.15625in"}

A storage pond, storage tank, covered dry stack, or anaerobic lagoon can
be a terminal component in the waste management train. However, a
solid-liquid separator, uncovered dry stack, and anaerobic lagoon with
external storage all require an appropriate subsequent liquid storage
component.

The first time the component drop-down list is accessed, all of the
available components will be identified as "new". Once a component is
selected for a management step, it will appear on subsequent drop-down
lists and is available for use in other waste stream management steps.
For example, if "New Storage Pond" is selected for one management step,
the next time the drop-down list is accessed this pond will appear as
"Storage Pond #1". This pond could then be selected for another waste
stream. However, if a second storage pond is desired, "New Storage Pond"
would be selected. Subsequent access to drop-down list would identify
this pond as "Storage Pond #2."

When the "Solid-Liquid Separator" component is selected, another
drop-down list is accessed that gives a list of separator types.

**Component Volumes (cu. ft/day) -** the relative volumes of materials
stored within the different structures. The solids portion of manure
removed by the use of a solids separator is not subtracted from the
solids storage volume of a storage pond or lagoon. Therefore, the size
of the lagoon or storage pond is NOT reduced due to the use of a solids
separator.

[]{#DesignScreen .anchor}The Design screen will reveal tabs for each of
the storage or treatment facility components, except solid-liquid
separation facilities, that were selected on the Management Train screen
as shown below.

[]{#DryStackDesign .anchor}**Dry Stack Design Screen (Covered and
Uncovered)**

The AWM design of dry stacks is the same for both uncovered and covered
stacks with the exception that the precipitation falling on an uncovered
dry stack is directed to an anaerobic lagoon, waste storage pond or
tank. Therefore, from a sizing standpoint, both covered and uncovered
design screens are the same. Even though the design screen for a covered
dry stack is illustrated, it applies to uncovered as well.

**Option 1**. **[Simple four-sided stacking structure]{.underline}**

![](media/image101.jpeg){width="6.558333333333334in"
height="7.183333333333334in"}

To design a dry stack facility the following entries are needed on the
dry stack design screen in AWM:

**Storage Depth** -- Click on the input cell and enter the value for the
preferred depth in feet (not including freeboard) for the dry stack
facility.

**Input Dimension** -- Click on the drop-down list box and select the
dimension, bottom width or bottom length, on which to base the dry stack
design.

**Bottom Width, Length** -- Click on the input cell and enter the value
in feet for the dimension selected to base the design on, bottom width
or bottom length.

**Freeboard** -- Click on the input cell and enter the value for the
preferred freeboard in feet for the dry stack facility. NRCS does not
require a minimum freeboard value for dry stack facilities but
regulatory agencies may require a minimum freeboard value.

**Max. Storage Volume Method** -- To select the way AWM computes the
maximum storage volume needed in the dry stack facility click on the
![](media/image102.jpeg){width="0.22916666666666666in"
height="0.19791666666666666in"}radio button associated with the
preferred method.

For the ![](media/image103.jpeg){width="1.59375in"
height="0.17708333333333334in"} method the user needs to click on the
check boxes associated with the months when the dry stack facility will
be emptied. When a withdrawal month is checked, AWM assumes the dry
stack facility will be empty at the end of the months selected.

For the ![](media/image104.jpeg){width="1.5104166666666667in"
height="0.17708333333333334in"} method the user needs to select the
number of months from the drop-down list or input the number of months
of storage preferred. For a dry stack facility design AWM determines
which month or group of consecutive months during the year for the
storage period specified requires the greatest storage volume and sizes
the facility accordingly. The critical months for design are displayed
in the cross section area of the design screen. To design for less than
1 month of storage select \"1\" for the months of storage and another
drop-down list will appear where you may select the number of days of
storage.

AWM will compute the required dimensions of the facility based on the
entered values.

Note: The dimensions at the top of the screen will also include the
computed top width and top length of the stack. If the combination of
side slope, stack height and bottom length or width causes the top width
or length to become negative, the program will display the following
message in the status bar:

![](media/image105.jpeg){width="6.179861111111111in"
height="1.5972222222222223in"}

If this warning message is displayed, modify the input values depth (D),
sideslope (Z), bottom width (W) or length (L) to properly size the
facility and eliminate the warning message.

**Option 2 -- [Setting the Wall Height for a Dry Stack
Facility]{.underline}**

AWM provides an option on the design screen to set the wall height and
stack height for a dry stack facility. The following inputs are needed
when the ![](media/image106.jpeg){width="1.0833333333333333in"
height="0.21875in"}check box is selected on the design screen for a dry
stack facility:

**Wall Height** -- Click on the input cell and enter the value for the
preferred wall height for the dry stack facility. Note that if zero is
entered for the wall height the program assumes a slab is being sized
for a dry stack facility.

**Storage Depth** -- Enter the depth that the material will be stacked.
This value may be higher than the wall height.

**Input Dimension** -- Click on the drop-down list box and select the
dimension, bottom width or bottom length, on which to base the dry stack
design.

**Bottom Width, Length** -- Click on the input cell and enter the value
in feet for the dimension selected to base the design on, bottom width
or bottom length.

**Freeboard** -- Enter the value for the preferred freeboard in feet.
Note that this dimension will set the assumed maximum height that the
material will be stacked against the walls. In the example shown above,
the assumed depth of material will be stacked 3.5 feet against the walls
and 6 feet total in the center.

Note the difference in the definition of freeboard between options 1 and
2. In option 1, the freeboard is added to the storage depth to compute
the total wall height. In option 2, the wall height is set by the user,
so the freeboard determines the height that the material is stacked
against the wall.

**Side Slope** -- Click on the input cell and enter the value for the
assumed slope of the stacked material within the facility. The side
slope entered is considered to be uniform on all four sides of the
stack.

preferred method.

For the ![](media/image103.jpeg){width="1.59375in"
height="0.17708333333333334in"} method the user needs to click on the
check boxes associated with the months when the dry stack facility will
be emptied. When a withdrawal month is checked, AWM assumes the dry
stack facility will be empty at the end of the months selected. To
design for less than 1 month of storage, select all the months and
another drop-down list will appear where you may select the number of
days of storage, as shown above in Option 1. 

For the ![](media/image104.jpeg){width="1.5104166666666667in"
height="0.17708333333333334in"} method the user needs to select the
number of months from the drop-down list or input the number of months
of storage preferred. For a dry stack facility design AWM determines
which month or group of consecutive months during the year for the
storage period specified requires the greatest storage volume and sizes
the facility accordingly. The critical months for design are displayed
in the cross section area of the design screen. To design for less than
1 month of storage select \"1\" for the months of storage and another

storage, as shown above in Option 1.

![](media/image108.jpeg){width="5.1375in" height="0.9736111111111111in"}

AWM will compute the required dimensions of the facility based on the
entered values.

Note: The dimensions at the top of the screen will also include the
computed top width and top length of the stack. If the combination of
side slope, stack height and bottom length or width causes the top width
or length to become negative, the program will display the following
message in the status bar:

![](media/image105.jpeg){width="6.179861111111111in"
height="1.5972222222222223in"}

If this warning message is displayed, modify the input values depth (D),
sideslope (Z), bottom width (W) or length (L) to properly size the
facility and eliminate the warning message.

**Option 3 -- [Pad Design]{.underline}**

You can size a pad to stack material by checking the box for "Set Wall
Height", then entering zero for the wall height.

Enter the depth of storage, the bottom width or length, and the assumed
side slope of the stacked material. Then, define the storage volume
method and enter the length of storage as described above in option 1.
An example of a pad design is shown in the following figure.

![](media/image109.jpeg){width="5.752083333333333in"

[]{#DesignStoragePond .anchor}**Storage Pond Design**

The design of storage ponds in AWM allows the user to define a
rectangular or circle type pond. AWM bases the design on the storage
depth, bottom width or length, permanent additional storage, freeboard,
sideslope ratio and maximum storage volume method inputs made by the
user.

The following screen illustrates a rectangular storage pond design based
on defining withdrawal
months:![](media/image110.png){width="1.2291666666666667in"
height="0.23958333333333334in"}![](media/image111.png){width="1.2291666666666667in"

![](media/image113.png){width="1.8576388888888888in"
height="0.2048611111111111in"}

For a storage pond design is based on a storage period or withdrawal
months, AWM determines which set of consecutive months during the year
requires the greatest storage volume and sizes the facility using the
user's decision on Total Depth of the structure.

The following screen illustrates a circular storage pond design based on
defining a storage period:

![](media/image114.png){width="6.247916666666667in"
height="5.117361111111111in"}

![](media/image115.png){width="1.4104166666666667in" height="0.2in"}

Storage depth is the Total Depth of the pond, as selected by the user,
less freeboard, depth of 25-yr., 24-hr. precipitation, depth of 25-yr.,
24-hr. storm event runoff, and depth of precipitation less evaporation
option selected on the Climate screen. Permanent additional Storage may
be required to meet management goals or regulatory requirements (see
NRCS Practice Standard 313, Waste Storage Facility).

The following screen illustrates the soil liner design option for a
storage pond:

![](media/image116.png){width="6.243055555555555in"

height="0.4479166666666667in"}

The liquid depth AWM uses for designing the soil liner is based on the
total depth of the pond less freeboard, depth of 25-yr., 24-hr.
precipitation, and the depth of the 25-yr., 24-hr. storm event runoff.
NOTE: this will increase the total depth shown on the schismatic.

The following screen illustrates the parallel ramp design option for a
storage pond:

![](media/image119.png){width="6.249305555555556in"

storage pond design:

![](media/image124.png){width="6.242361111111111in"
height="4.967361111111111in"}

A stage-storage curve defines the relationship between the depth of
liquid and the storage volume available within a structure.

Volume Stored: measured from the bottom of the structure, how much
liquid has been stored or how much more liquid can be stored.

Volume Remaining: measured from the top of the structure, how much
liquid remains after pumping, or how much liquid can be pumped.

[]{#DesignStorageTank .anchor}**Storage Tank Design**

The design of tanks in AWM allows the user to define a rectangular or
circular type tank. AWM bases the design on the storage depth, bottom
width or length, permanent additional storage, freeboard, precipitation
excluded or not and maximum storage volume method inputs made by the
user.

The following screen illustrates a rectangular tank design based on
defining withdrawal
months:![](media/image110.png){width="1.2291666666666667in"

height="0.19027777777777777in"}

For a tank design based on a storage period, AWM determines which set of
consecutive months during the year for the storage period specified
requires the greatest storage volume and sizes the facility accordingly.

The following screen illustrates a circular tank design based on
defining a storage period and excluding
precipitation:![](media/image128.png){width="1.2083333333333333in"

[]{#DesignAnaerobicLagoon .anchor}**Anaerobic Lagoon Design**

The inputs for the design of anaerobic lagoons in AWM are very similar
to the design of a storage pond. AWM allows the user to define a
rectangular or circular type lagoon. AWM bases the design on the storage
depth, bottom width or length, permanent additional storage, freeboard,
sideslope ratio, sludge accumulation period and maximum storage volume
method inputs made by the user.

The following screen illustrates a rectangular anaerobic lagoon design
based on defining withdrawal
months:![](media/image110.png){width="1.2291666666666667in"

![](media/image113.png){width="1.6819444444444445in"
height="0.18333333333333332in"}

For an anaerobic lagoon design based on a storage period, AWM determines
which set of consecutive months during the year for the storage period
specified requires the greatest storage volume and sizes the facility
accordingly.

The following screen illustrates a circular anaerobic lagoon design
based on defining a storage period and using the Rational Design
Method:![](media/image136.png){width="1.2993055555555555in"

height="0.22083333333333333in"}

Permanent additional Storage may be required to meet management goals or
regulatory requirements (see NRCS Practice Standard 359, Waste Treatment
Lagoon). At least 1 year of sludge accumulation period should be entered
to account for sludge buildup in the lagoon.

The following screen illustrates the soil liner design option for an
anaerobic lagoon:

![](media/image140.png){width="6.241666666666666in"

height="0.4166666666666667in"}

The liquid depth AWM uses for designing the soil liner is based on the
total depth of the lagoon less freeboard, depth of 25-yr., 24-hr.
precipitation, and the depth of the 25-yr., 24-hr. storm event runoff.
NOTE: this will increase the total depth shown on the schismatic.

anaerobic lagoon design:

![](media/image145.png){width="6.247916666666667in"
height="4.902083333333334in"}

A stage-storage curve defines the relationship between the depth of
liquid and the storage volume available within a structure.

Volume Stored: measured from the bottom of the structure, how much
liquid has been stored or how much more liquid can be stored.

Volume Remaining: measured from the top of the structure, how much
liquid remains after pumping, or how much liquid can be pumped.

[]{#DesignAnaerobicLagoonExtStorage .anchor}**Anaerobic Lagoon with
External Storage**

The anaerobic lagoon with external storage design option utilizes an
anaerobic lagoon to contain the minimum treatment volume. All other
volume requirements are contained in the storage facility that must
follow the lagoon in the management train. The only time this lagoon
would be emptied would be for sludge removal.

The following screen illustrates a rectangular anaerobic lagoon with
external storage

height="0.17916666666666667in"}

Storage depth is the total depth of the lagoon less freeboard. Since
lagoons with external storage do not provide storage, an additional
storage component must follow this type of facility in the management
train.

The following screen illustrates the soil liner design option for an
anaerobic lagoon with external storage:

![](media/image151.png){width="6.241666666666666in"

[]{#ManureMaster .anchor}Manure Master is a simple screening tool that
can help assess the relative potential for the nutrients contained in
the animal manure from an animal feeding operation to meet the crop
uptake and utilization requirements for those crops that receive
applications of manure. Manure Master calculates a balance between the
nitrogen, phosphorus, and potassium content in the manure and the
quantity of these nutrients used by crops. This balance can be
calculated based upon recommended fertilizer application rates, when
known or upon estimated plant nutrient content, when recommended
fertilizer application rates are not known. For nitrogen, the balance is
calculated taking into account expected losses from leaching,
denitrification, and volatilization. Manure Master is not a nutrient

The AWM program uses Microsoft Access to preview and print a report.
Using the export tools within Microsoft Access the user can export a
report to a Microsoft Word or Excel file so it can be formatted and
saved by the user. The only limitation to creating custom reports for
use in the AWM program is the user's knowledge level on how to create
and edit reports using Microsoft Access.

## AWM MMP Input Report 

This report can be used to manually transfer data to the Purdue Manure
Management Planner (MMP) program. The NRCS Animal Waste Management (AWM)
program is used to analyze the capacity of an existing manure storage
facility or to size a new facility. The design inputs for the AWM are:

-   Number & type of livestock (has option of manure production tables)

-   Bedding (uses table of effective density for bedding types)

-   Wastewater

-   Surface area of contributing runoff (calculates monthly rainfall
    volume based on county rainfall tables)

In addition the AWM calculates the volume of runoff & rainfall resulting
from a 24 hr- 25 yr frequency storm.

The MMP program is used to determine nutrient allocations for fields
receiving manure. The design inputs to determine manure production
volume are:

-   Number & type of livestock (can share a common table with the AWM)

-   Bedding

-   Wastewater

By default the MMP estimates the rainfall volume appropriate for the
type of storage facility and calculates "estimated manure production" as
displayed in the "analysis" tab. From this estimated total manure volume
the MMP then displays nutrient concentrations on the analysis tab.

In the "storage tab" the MMP has a calculator that can be used to
determine the volume of an existing storage facility. The MMP then uses
the storage volume, manure production volumes, and manure application
schedule in a mass balance to develop the nutrient management plan.

The differences in the AWM and MMP become apparent with the design of a
manure storage facility that is subject to runoff inputs. This is
because the MMP estimates the runoff and rainfall entering a storage
facility. Thus, the most accurate assessment of a storage pumpable
capacity and measured annual production volume is when the AWM is used
to calculate the total annual production and storage capacity, and
generate a report with the data by the AWM to be inputted into the MMP.
These are the steps:

-   Run the AWM to determine the storage volume of an existing facility
    or to size a planned facility.

```{=html}
<!-- -->
```
-   Once the size of the facility(s) is (are) determined; open and print
    the "AWM MMP input" report from the "file", "report", "preview
    report" tab in the AWM. This report shows:

    -   Annual manure production linked to each manure storage facility
        (excludes volume from the 25-yr storm)

    -   Design Storage capacity of each facility (excludes volume from
        the 25-yr storm)

    -   Annual raw manure production volume from livestock (this data is
        shown for comparison to raw manure data displayed in the MMP so
        the user can verify the selected manure source table)

-   Open the "Animals" tab in the MMP. Populate the columns with the
    same animals used to run the AWM; however, do not populate the
    "extra water" and "bedding" columns. The MMP will use this data to
    estimate manure production and nutrient concentrations and display
    the data in the "Analysis tab".

-   Open the MMP "Storage tab". Populate each column with the same
    "storage ID" and "Storage type" from the "AWM MMP input" report.
    Then enter the "Spreadable or Pumpable capacity" for each identified
    storage facility.

-   Open the MMP "Analysis tab" and enter the "Measured Manure
    Production" volume from the "AWM MMP input" report into the MMP
    "Measured Manure Production" column. Note that the MMP will then
    recalculate nutrient concentrations based upon raw manure data,
    measured manure production, and default value storage nutrient loss.

-   Continue running the MMP as usual. The program will now more
    accurately be able to balance manure production & storage to manure
    removed for land application.

**Determining storage volume of an existing facility**

This is a trial and error process;

1.  First input animals, bedding, wastewater and any other production
    inputs as they exist.

2.  Designate the storage type in the Mgmt Train screen

3.  Size the storage to match the existing component dimensions. Field
    inventory work or as-built construction drawings will be needed.

If the storage dimensions can NOT be matched with the current production
inputs then use the production information to obtain the Measured Annual
Production volume needed for MMP (Analysis Tab).

Trial 2 for sizing an existing storage component;

1.  From the previous information clear out all the bedding, wastewater
    and any other production inputs to zero, while maintaining a storage
    period of at least 6-months. Keep the animal input information to
    work from. In the design screen click on the Animals screen so you
    can view both screens at the same time.

![](media/image193.png){width="5.9944444444444445in" height="4.2in"}

2.  Now manipulate the number of animals in the animal screen to obtain
    the existing storage dimensions. As you change the animal numbers
    the storage dimensions will change in the design screen. For this
    example the storage pond is 10 ft deep, 3:1 sideslopes, 100ft x
    200ft top dimensions. Through trial and error by changing the animal
    numbers you can get within .3ft of a foot to the actual storage
    dimensions of the existing structure.

![](media/image194.png){width="5.9944444444444445in"
height="4.247916666666667in"}

3.  Once you obtain the existing storage dimensions then run the AWM MMP
    Input Report to obtain the Spreadable or Pumpable Capacity (for MMP
    "Storage" tab), or you can run the AWM Storage Pond Data report to
    obtain the same information. Keep in mind that the production
    volumes are incorrect and through trial and error we are obtaining
    only the storage capacity information.

4.  The use of AWM through this method of sizing an existing storage
    facility is limited to the conventional storage shapes within AWM.
    Other software such as AutoCAD maybe better utilized for none
    conventional storage shapes in estimating storage capacities of
    existing facilities.

# Chapter 6 -- Modifying the AWM Database

[]{#ModifyDatabase .anchor}The AWM database has four tables, all of
which can all be modified. They are:

-   Climate

-   Animals

-   Bedding

-   Separators

**Note: Changes made to the database do not take affect until AWM is
exited and then restarted.**

The tables within the AWM database are accessed from the main AWM menu
by first clicking on Data and then clicking on the table to be modified
as illustrated in the following screen:

![](media/image206.png){width="6.246527777777778in"
height="0.9798611111111111in"}

If AWM is being used for the first time, the database may not be the
most up-to-date database available. Refer to Chapter 2, Installing and
Starting AWM for instructions on how to download the current database
from the NRCS National Water and Climate Center webpage.

## Editing Climate Data

There are several ways that climate data can be edited or added to the
climate data table. Each method is described in the following
instructions.

To edit existing climatic data, select the Data -\> Edit Climate Data
and the following screen will appear:

![](media/image207.png){width="2.7395833333333335in"
height="1.3125in"}![](media/image208.png){width="0.7916666666666666in"
height="0.25in"}

![](media/image209.png){width="6.247222222222222in"
height="4.829166666666667in"}

The following screen illustrates how to add a climate station to the
climate database:

![](media/image210.png){width="4.55625in"
height="3.522222222222222in"}![](media/image211.png){width="0.5833333333333334in"

height="0.25in"}

After completing data entry for new climate stations, close the Edit
Climate Data screen by clicking on the
![](media/image171.png){width="0.21875in" height="0.21875in"} in the
upper right hand corner of the screen. After exiting and restarting AWM,
the new climate station will have been positioned in alphabetical order
by state, county, and climate station.

## Importing Climate Data

You can import climate data from a file that is in comma delimited
format. The file must have all of the fields in the same order as they
appear in the climate data table. The file should not have a header row
and should have one climate station per line. The file can have as many
lines as desired. When importing data, if a value already exists in the
table, a dialog box will popup and ask if it is OK replace the value
that is in the database.

There are several ways to build a data file for import into AWM. One way
is to use Microsoft Word to develop the data and then save it as a text
file(.*txt*). Another way is to use Microsoft Excel to develop the data
and then save it as a comma delimited file(.*csv*). The order of data is
State, County, Station, 25-year 24-hour precipitation, January
precipitation, February precipitation, March precipitation, April
precipitation, May precipitation, June precipitation, July
precipitation, August precipitation, September precipitation, October
precipitation, November precipitation, December precipitation, January
evaporation, February evaporation, March evaporation, April evaporation,
May evaporation, June evaporation, July evaporation, August evaporation,
September evaporation, October evaporation, November evaporation,
December evaporation, Barth's Kval, anaerobic lagoon volatile solids
loading rate, volatile solids loading rate for odors and Rational Method
maximum anaerobic lagoon volatile solids loading rate.

An example of one line of climatic data follows:

OR, East, New, 4.00, 6.90, 4.79, 4.33, 2.29, 2.09, 1.39, 0.35, 0.57,
1.46, 3.98, 6.08, 6.85, 0.26, 0.52, 1.04, 1.82, 3.12, 3.90, 5.72, 4.68,
2.86, 1.30, 0.52, 0.26, 0.60, 5.25, 0.0038,0.00625

Each line of the file should have 34 pieces of data separated by commas.
The import will fail if this convention is not precisely followed. A
space after the commas may be included or not used.

The following demonstrates saving the above line of data entered into
Microsoft Word as a text file:

The imported file will appear as the first line for the State in the
climate data table. After exiting and restarting AWM, the records will
be resorted into alphabetical order by state, county and weather
station.

A climate file developed in Microsoft Word can also be imported using
the same procedure described for a text file but instead of selecting a
![](media/image217.png){width="1.5625in" height="0.15625in"} file type
you select ![](media/image227.png){width="0.9194444444444444in"

After quitting and restarting the program, the new animal added will be
sorted into alphabetical order by Name and Data Source.

Animals added that are lactating are indicated with a one (1) in the "Is
Lactating" column. This is to associate the animal with a flush water
volume indicated in the "Flush Water Vol" column in the Flush Water
Calculator on the Additions Screen.

## Editing the Bedding Data

Editing the bedding data table is very similar to editing the animal
data table. Data may be edited within the data table or new bedding data
can be added or existing bedding data deleted. The following screen
illustrates how to add bedding data called "New
Bedding":![](media/image234.png){width="0.59375in"

The separator data table contains efficiency values for liquid/solid
separators by the type of separator. Data may be edited within the data
table, a new separator can be added, or an existing separator can be
deleted. Adding a separator called "New Separator" is demonstrated on
the following screen:
