  1. HL-RMSNWS Hydrologic Lab Research Modeling System HIC Conference – Kansas City October 27-29, 2003 Billy Olsen ABRFC HIC

  2. Outline • 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

  3. 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)

  4. 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

  5. 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

  6. 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.

  7. 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).

  8. 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

  9. 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.

  10. 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.

  11. 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.

  12. 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.

  13. 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 .

  14. 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)

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

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

  21. 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.
