## Definitions

- HL-RMS...Hydrologic Lab Research Modeling System...evolved from initial modules to test concepts and now is in limited released for research work.
- DMS 1.0 – HL Distributed Modeling System Version 1...prototype, more user friendly version for evaluating operational potential
- XDMS – User interface and display system included in DMS 1.0 (ABRFC)

## History

**March 1993**, HRL/ABRFC PROTEUS DM Plan Short-term – UHG Warping (kinematic routing w/GIS to shift UHGs)                             Longer-term – Compare models...gridded and semi-distributed (lumped)...then decide on direction
**1993-1995** – ABRFC project w/U of OK – Baxter Vieux...problems w/precip accuracy, crude software & inadequate hardware

## History

**June 1996** HRL DM Scale Issues – M Smith, Seo, Finnerty & Koren – Illinois Basin OK/AR
**Aug 1997** MAP vs MAPX– Finnerty & Johnson
**1998** MIT MAP/MAPX
**Jun 2000** Wang et.al.–longer term MAP/MAPX
**1998-1999** HRL M Smith et al – Distributed vs lumped for Illinois then Blue River Basin OK
**Oct 2000-2002** – DMIP Illinois & Blue & HL-RMS

## History

- In **2001**, OHD agreed to release the HL-RMS to ABRFC  in order to assist with testing validity and calibration strategies
- Most of **2002** – Focus was to increase the runtime speed of the model, look at potential calibration schemes, evaluate model results and devise/envision operational usefulness.

## History

**April 2003** – OHD released a Linux version.
- The Linux version was the developed to address the runtime limitations the program displayed on the Unix Platform.  Model run-time speeds  improved by a factor of 10! (not latest release)
- For a median sized basin (1859 sq mi.) and duration of  5 months: 5 minutes (Linux) compared to 50 Minutes (Unix).

**Notes:**
The Linux run time was obtained before the new XDMS/HL-RMS Release. 

If asked, the basin used in the timing test was BlKO2.

## History

**Spring 2003**
- Even with model run times addressed, calibration was cumbersome due to limitations with ICP.
- ICP inaccurately plots timeseries with differing time steps.
- APEX contractor joins the OHD/ABRFC team to develop DMS 1.0 (address the calibration & display issues, improve the model & outline path to AWIPS).
- 5/03 requirements, 9/03 development, 12/03 test 1.0

**Notes:**
ICP shifted the timeseries with respect to each other and time  a you scrolled across the screen. Hence in analysis, you could never be certain which plot was accurate or determine how HL-RMS performed in comparison to the observed flow or NWSRFS output.    

## History

**May 2003 – September 2003** - Team roles defined:
- APEX focused on improving model run times.
-  ABRFC developed interface software and associated documentation. Eval calb/ops.
- OHD worked on model enhancements and oversaw integration of software.

**Notes:**
I touched base with Lee on 10/22/03 to confirm APEX’s level of involvement with DMS1 as well as OHD’s contributions. 

## Current Status

**October 2003** – OHD/APEX released the integrated XDMS and HL-RMS program along with a few add on programs.
- Some of the features of HL-RMS (Hydrologic Model)
- Runs in a Linux environment.
- Maintains rainfall inputs on an hourly HRAP grid Scale.
- Can incorporate gridded SAC-SMA parameters as well as gridded PE information derived from CAP data, or can incorporate basin lumped parameters.

**Notes:**
I highlighted just a few of capabilities of the program. Let me know if you need more input or further clarification.  

## Current Status

- XDMS/HL-RMS Beta Release
- HL-RMS Features (Cont)
- Separates the runoff components
- Surface flow: includes impervious, surface and direct runoff .
- Subsurface flow: includes interflow and baseflow.
- Calculates and internally maintains SAC content capacities on a HRAP grid scale.
- Can utilize a kinematic method for hillslope and channel routing or the Unit Hydrograph Theory.
- Generates a variety of user defined output gridded displays such as SAC contents and routing contents for a given hour(s) during the model run.

**Notes:**
For Feature #3 (Routing techniques) – the technique the model uses is defined in the @I card which is the same card that defines a basin in the model. I have not yet tested the Unit Hydrograph option to understand how it works and if it can be applied to downstream locations where the local runoff has little effect on the actual flow. 

## Current Status

- XDMS/HL-RMS Beta Release
- Features of XDMS (interactive viewing program)
- Allows for both a Calibration and Forecast Mode.
- Includes the capability to run the HL-RMS program from within the XDMS environment.
- Allows for text editing of the connectivity file and input deck from within XDMS.
- Displays a variety of overlay information.

**Notes:**
Again I  highlighted only a few of the features of the XDMS program.

## Current Status

- XDMS/HL-RMS Beta Release
- XDMS program
- Displays gridded output of the HL-RMS Model.
- Displays timeseries output (OH-Data Card format)  in a hydrograph Plot window.
- Six-hourly NWSRFS lumped model flow output.
- Hourly observed flow.
- Hourly HL-RMS calculated flow outputs.
- Hourly precipitation inputs .

## Future

**Now** - DMS 1.0 Released to WGRFC & CBRFC (within a few weeks)
**Dec ’03** – Testing completed (ambitious)
**Early ’04** – Decisions concerning DMS 1.x (further improvement/testing cycle) or DMS 2.0 (AWIPS)

## Example of XDMS Graphical Display Capabilities

## Hydrograph Plot 

- HL-RMS output using NWSRFS  SAC-SMA & PE data.

- HL-RMS output using NWSRFS SAC-SMA data & CAP PE

- BLKO2 Observed Flow

- Observed flow.

**Notes:**
Sample hydrograph plot. Even though 8 timeseries “appear” in the hydro time series box, you are only looking at  3. The  white box indicated that the timeseries is plotted while the black indicates that the timeseries is inactive (this is a simple toggle.)

The Mustard line is the observed flow timeseries for BLKO2.

The Red line is HL-RMS timeseries output. I  used the calibrated  NWSRFS SAC-SMA data (non gridded) and the CAP PE and PE adjustment data (gridded) for the input definitions. 

The Blue line is a second HL-RMS timeseries output. For this timeseries I used the calibrated NWSRFS SAC-SMA data as well as the PE and PE adjustment (monthly mean values) defined in NWSRFS which are used if the daily mean PE value cannot  . 

Notice: At times the Red line is closer to the observed (mustard line) while at times the Blue one is; hence indicating the impact of PE ad different times and even on Peak flows. 

## Six-Hourly Precipitation AccumulationsDates: 6/26/97 00z – 6/27/97 00z 

- Six-Hourly Precipitation AccumulationsDates: 6/26/97 00z – 6/27/97 00z

**Notes:**
Loop of the Radar information. The event highlight correlates with the previous slide of the first “action stage”  response.

The images do show  6 hour total accumulations. The first image ends at 06Z. Also note that the bulk of the precipitation fell between  00Z and 12Z on the 26th.

Also, I wrote this presentation in MS PowerPoint 2000 if the version you use to give the presentation is earlier, it may not loop through  the graphics twice.   

## Synoptic Hour Snapshot of Subsurface RunoffDates: 06/26/97 06Z – 6/27/9718z

**Notes:**
This is a snapshot  showing hourly images every 6 hours beginning with 6Z. This is indicating  the Subsurface flow which incorporates the interflow and baseflow components for each grid. 

*Note any of the following hourly grids can be generated for any specified time frame and in any timestamp evenly divisible into 24. So we can create these 1 hour grids every hour, every 2 hours, 3 hours, or etc. Note though that for the BLKO2 basin alone the size of the grid file is around 200 KB. So as we expand to more basins we may be looking at a space resource problem.   

## Synoptic Hour Snapshot of Upper Zone Tension Water ContentsDates: 6/26/97 00Z – 6/27/97 18Z

- Synoptic Hour Snapshot of Upper Zone Tension Water ContentsDates: 6/26/97 00Z – 6/27/97 18Z

**Notes:**
Again, this is a snapshot  showing hourly images every 6 hours beginning with 00Z. This is indicating  the actual (not a percent full) of the Upper Zone Tension Water Contents (Bucket.) 

## Synoptic Hour Snapshot of Channel Routed FlowDates 6/26/97 00z – 6/27/97 18z

- Synoptic Hour Snapshot of Channel Routed FlowDates 6/26/97 00z – 6/27/97 18z

**Notes:**
Again, this is a snapshot  showing hourly images every 6 hours beginning with 00Z.
The actual parameter is the areac output. Basically this is the in channel routed flow from Cell to Cell. Also, as a basin is defined, the Basin.hyd timeseries file is delineated form this output. Hence is how OHD advertises that flow can be obtained for interior points with in a basin.

## Closing Thoughts

- XDMS/HL-RMS Model Shows Great Promise.
- Prototype in the hands of the field.
- Hope for exploiting high space/time resolution data for convection driven flooding in areas of the U.S. w/lower annual runoff (10-15in).
- Flash Flood tool.
- Inundation mapping tool.
- Results thus far encouraging.
- Issues which still need to be addressed:
- Development of a calibration scheme.
- Incorporation of a Snow Model.
- Incorporation of Dams and Reservoir structures.
- Incorporation of the functionality of Mods for forecast operations.
- Need “hard numbers” comparing models.

**Notes:**
Just a few of the ideas  discussed when determining the requirements list.
