Tim,

I was wondering if the seats are still available for the WASP Workshop?
If there still are available seats, could you please sent me some
additional information on the course? The dates in this email do not
match the dates on the epawasp website, could you please let me know the
actual dates?

Thanks,

We still have a limited number of seats available for the upcoming Water
Quality Analysis Simulation Program (WASP) Workshop in Atlanta.


Water Quality Analysis Simulation Program (WASP7.2) Workshop
                      Atlanta, GA
                    July 23-27, 2007

WASP7 is an enhanced Windows version of the USEPA Water Quality Analysis
Simulation Program (WASP). WASP7 has been developed to aid modelers in
the implementation of WASP.  WASP7 has features including a
pre-processor, a rapid data processor, and a graphical post-processor
that enable the modeler to run WASP more quickly and easily and evaluate
model results both numerically and graphically.
With WASP7, model execution can be performed up to ten times faster than
the previous USEPA DOS version of WASP.  Nonetheless, WASP7 uses the
same algorithms to solve water quality problems as those used in the DOS
version of WASP.

WASP7 is used routinely throughout the United States in the development
TMDLs and waste load allocations.  The model contains algorithms for
conducting: 1) Eutrophication/Conventional Pollutants,
2) Organic Chemicals/Simple Metals, 3) Mercury, 4) Temperature, Fecal
Coliforms, Conservative Pollutants.

WASP7 contains 1) a user-friendly Windows-based interface,
2) a pre-processor to assist modelers in the processing of data into a
format that can be used in WASP, 3) high-speed WASP eutrophication and
organic chemical model processors, and 4) a graphical post-processor for
the viewing of WASP results and comparison to observed field data.

I'm trying to delineate a watershed using a DEM from the NJDEP.  The NJDEP
DEM have a resolution of 10 m so I would like to use them for greater
accuracy.  For some reason I can not use them in the delineation.  They
worked fine in the other versions of BASINS.  When I try to use it for the
set up and preprocessing section I get an error message of "An error
occurred while filling the grid: attempted to read or write protected
memory.  This is often an indication that other memory is corrupt."  What
does that mean?  

 

After I gave up using the NJDEP DEM's I used the one provided from Data
download in Basins.  I wanted to delineate to 6 different points on the
stream.  After the delineation was complete there were much more subbasins
than 6.  I looked in the Basins Documentation and under Delineate a stream
to a point it shows delineating to 2 points in the stream but having many
more subbasins that 2.  I want to delineate the stream so the number of
outlets I choose in the "Custom Outlet." section will produce the same
number or subasins.

Sean,

I'm not sure about your first question. It is possible though that this is =
a
grid format issue.  Are you using ESRI formated rasters for  your NJDEP
data?  As for your second question, the aggregation of basins to your
selected outlets did not make it into the initial release of BASINS 4.
However, both of these issues (assuming I'm right about your file formats)
are addressed in the BASINS 4 patch that is coming out soon.  In the mean
time you can do a work around on problem one by converting your files to a
different format before running them in BASINS (e.g. geotiff).

Subject: [basinsinfo] Hourly flow from WinHSPF

Dear everyone:

I produced hourly inputs to WinHSPF. However, I only get the daily
streamflow output. Any suggestions on how I can obtain the hourly flow
output?

Thanks!

Kevin

Subject: Water withdrawals

Hi All,

I need to "withdraw" a certain volume/flow from our stream outlet to
simulate (basically) a large spring that is being fed from within our
target watershed.       I've tried using DEEPFR to model this spring but
no luck.  I need to model it as a constant withdrawal, which would be
similar to an irrigation or process demand.  I've never done this with
HSPF before, but I imagine it has to be a fairly "standard" procedure, so
any help/input appreciated!

My first take is that it would be done by setting HYDR-PARM1 variable
ODGTFG to 1... Am I on the right track?  If so, are there other flags I
need to set, and I'm assuming I'll need to set up a time series in the WDM
to let HSPF know how much is being withdrawn?

Thank you!

Subject: RE: Water withdrawals

Joe,

If I understand correctly, the spring outflow is outside your basin, so
you want to subtract it from
the surface flow at the outlet, to reflect the reduced baseflow that is
being diverted to the spring.

First, add an exit to the RCHRES in GEN-INFO to represent the water
withdrawn. For example, if it=20
currently has only 1 exit, declare it as 2 exits, for surface outflow
and springflow, respectively. =20
Then ODGTFG(2)=3D 1 and ODGTFG(1) remains unchanged (generally 0), while
ODFVFG for each exit would=20
remain unchanged (e.g. generally 4 for downstream surface flow and 0 for
the spring).  No FUNCT=20
values need to be changed.  If your original downstream discharge was
more complicated to start with,
you'll have to adjust these changes accordingly.

Be sure you output O(1) instead of RO, OVOL(1) instead of ROVOL, etc, to
analyze the actual surface outflow.

Then as you say, add the constant timeseries to the WDM.

Finally add a line to EXT SOURCES that passes the appropriate WDM
dataset number to RCHRES nnn EXTNL OUTDGT 1.

Hope this helps,

Subject: Re: How to create my own REACH FILE?

You only need the stream tracing in a GIS shapefile (the 15 sec. data is
fine) or GRID plus a digital elevation dataset (DEM) for delineation.
You do NOT need to recreate a REACH file.

In order to run the HSPF water model you will also need a landuse GIS
file.
The HSPF model also requires precipitation (rain) and temperature time
series data.
For test purposes you can use one of the prepared state WDM files from a
representative (climate and latitude/longitude) area in the US. But to
calibrate your specific watershed you will also need daily gage data in
a time series.

Hi=20

I am not sure what you mean by 15 second stream data but for sure you can =
create your own stream geometry and hydraulic data (FTABLE). The FTABLEs =
created by BASINS should not be rellied on as they are just an approximatio=
n from the DEM. I have used channel cross sections generated with ArcHydro =
for a flood mapping project with HEC RAS. I ran HEC RAS with several =
profiles to get data for my FTABLEs. Another source of data I have used is =
data from our baseflow surveys in our watersheds. The only difficulty I =
had with the baseflow survey cross sections is that they were collected =
during periods of low flows in the streams. I have therefore combined them =
with the BASINS generated cross sections. My results have been pretty =
good.

Wish you luck.

Subject: SWAT parameters: water

Hello all, I am currently using SWAT (BASINS 3.1) and have a question  
about out of range parameter fields for the crop name "water" in the  
Crop database: I ran the model (unsuccessfully) and created the  
parameter range report.  A number of my parameter values for the  
"water" crop name were zero, and showed up on the report as being out  
of range (ex. Bio_e, Bn1, Bn2, Bn3, Bp1, Bp2, etc).  I can change all  
of these parameters to the minimum values (as appropriate to the  
parameter), but this seems counterintuitive for some of the  
parameters, especially for those concerning "plant at maturity"  
values.  Should I just use the minimum values recommended in the  
Editor or is there something I am missing?  Of course, I dont want to  
change parameter values that will hurt the integrity of the model  
outputs.  My land use database was derived from the USGS 1992 coverage  
and I used the soils database embedded in BASINS.  Thank you for any  
help and advice!  Jon Franczyk

Sillah, this sounds like the known bug that occurs when you run AWD on ESRI
binary format grids.  Could that be what you are doing?  If so you should
convert your grids to another format first before running AWD (e.g. geotiff)
and/or wait for the BASINS 4 update that will be coming out soon. - Dan

Hello, I am using SWAT2000 (BASINS 3.1) and after editing my input  
files and running the model, I am getting an error message that reads:

"Error calling unlink for file"
Then a pathway to the file basins.bsb
"Return error code 13"

Any helpful information would be most appreciated, Jon Franczyk

David,

The second multiplier is (1 / drainage area) for your gage, not a fixed
number.  Its purpose is to convert from acre-inches (since the SCHEMATIC
block multiplies out all the inches by acres) back to inches, so that
the
output is in effect an area-weighted average of PERO/SURO/etc over all
of
the land segments that drain to the gage.

The first multiplier for ROVOL is (12 / drainage area) for the gage, to
Convert from acre-feet to inches.

Hope this helps,

 Dear BASINS Users,
What are the parameters that control the timing of the stream flow hydrograph? 
IRC and INTFW  seem control the hydrograph timing (Calibration manual). But 
when I changed these two parameters up and down, they did not change the timing 
of the hydrograph and  they did change the magnitude of flow (up and down). 
Other friends said that the channel length is too short? and I changed the 
channel length (hypothetically changed to know if it affects) into longer flow 
path, but it did not change the timing of the hydrograph. So what is the 
problem?  Is there any problem in hydrologic routing?
Is there any sensitivity between the timing of the hydrograph and any 
parameters in HSPH model? If so, could anyone tell me what are they?

Krispin,

Increasing the interflow parameters will change the shape of the storm
peak
(shorter and fatter).  Generally by virtue of this, the timing of the
peak
will be shifted slightly, but if the timing is off significantly due to=20
other issues (e.g. rainfall timing, or routing if you have several
reaches=20
above the gage), then you might not see the effect, especially in daily
output.

How much is your timing off?

Hi Tom,
Thanks for the reply. Actually I am simulating on the hourly basis. The problem 
is I don't have daily data inside my project area. Only the peak flow is 
measured by USGS ( but did not give the time to the peak ) so the calibration 
was done with the peak flow and some measured calibration parameters. So I am 
not sure how time is off from my simulation and thefore I tried to look at the 
sensitivity of the hydrograph timing respect to which paramters and to  compare 
it with some empirical method which is more conventioval way of calculating the 
"lag time" of the watershed.

Thanks 
Krispin

Krispin,

Changing the length of the channel in HYDR-PARM2 won't affect timing,
but
changing the assumptions built into the creation of the FTABLE can.  In
particular, the more storage it takes to reach a given flow, the longer
the lag to reach that flow.

Subject: HSPF: surface outflow temperature at PWTGAS

Hi, folks,

I simulated soil temperature and outflow temperature from 1999 to 2006 in the 
module of PERLND. The HSPF manual indicates that the temperature of each 
outflow is considered to be the same as the soil temperature of the layer from 
which the flow originates. So the temperature of the surface outflow is 
expected to equal to the surface layer soil temperature, the temperature of 
interflow to the upper layer soil temperature, and the temperature of 
groundwater outflow to the goundwater layer soil temperature. My simulated 
interflow and groundwater temperature is same to the expectation. But the 
simulated surface outflow is very strange.

My simulated surface layer soil temperature is mostly above 32oF, and has a 
peak at summer. But the simulated surface outflow temperature is constant to 
be 32oF from 1999 to early 2003, then increases to 42oF at mid-2003, after 
that slightly increases to 46oF till the end of 2004, then decreases to 32oF 
by the end of 2006. I don't know why the surface outflow temperature does not 
equal to the surface layer temperature as said in the manual. I inputted water 
temperature of reach manually by using EXT SOURCE module.

Do you have any suggestion for this problem?
Thanks in advance.

Mei

I would suggest reviewing your inputs for the PSTEMP module, which is

temperatures in PWTGAS.  If those look okay, then check your input
timeseries for air temperature.

Tom, Thanks very much for your suggestion.

I checked the inputs for PSTEMP,it looks everything is correct. And the 
simulated soil temperature of surface layer and upper layer has the same 
tendency as the air temperature and the water temperature. The temperature of 
lower layer is assumed to be constant as I set in the module. I also checked 
the air temperature input, but cannot find any problem.

I find another problem of the output of SOTMP (surface outflow temperature). 
The data series of SOTMP shows the temperature is around -1E+30, but the graph 
output displays the surface outflow temperature is 32oF or above as I 
mentioned in previous email. Is there any program failure here?

I am really appreciated for all help and suggestion.

Subject: RE: HSPF: surface outflow temperature at PWTGAS

Mei,

I omitted one detail before - when a soil layer temperature is below 0.5
C (32.9 F), it is
fixed to that value. =20

When I run your file, everything seems fine.  I changed the temperature
output to hourly, and
SOTMP=3D min(SLTMP,32.9) describes what I see perfectly.  The reason
you're only seeing a few
values is that surface runoff only occurs for a full day on rare
occasions, and WdmUtil skips
over all of the undefined values, making the plots appear flat in
between such days.

I've found as a general rule, if you're outputting concentrations (and
temp is just the
concentration of heat in different units) in surface runoff or
interflow, it's important to
write the datasets at the same timestep of the run, so that the
averaging in of undefined
values doesn't mask the real behavior of the system.

Dear Tom,

I am so happy you can help me look into my model. Attached zip files are
my model file and my wdm files. Could you kindly help me check there is
any problem in the model setting?

Thanks a lot.
Mei

Subject: SWAT output

Hello all, I am running SWAT from BASINS 3.1 and having trouble with  
an error message when I attempt to run the model. The error message is  
as follows:

Error calling unlink for file
C:\basins\.....\basins.bsb
Return error code 13

I have followed the instructions concerning this type of error (go to  
working directory, delete delta#.dbf files); however, there isn't any  
delta files in the directory. If anyone has any information as to what  
other problem this could indicate, please let me know. Thank you, Jon  
Franczyk
