  • Define HL-RMS, DMS & XDMS
  • Discuss History of HL-RMS
  • Current Status - XDMS/HL-RMS Beta Release
  • Future – WGRFC, CBRFC & DMS 2.0
  • Example Graphical Outputs
  • Closing Thoughts
  • 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).
  • 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
  • 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.
  • 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.
  • 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.
  • 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.
  • 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)

  • 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.
