Presentation Transcript

  1. Integration of Global Precipitation Measurement Data Product with theHydrologic Engineering Center-Hydrologic Modeling System The University of Mississippi Geoinformatics Center Lance D. Yarbrough, PI Joel S. Kuszmaul, Co-PI

  2. Experiment Collaborators • MRC–RPC team • Lance D. Yarbrough and Joel S. Kuszmaul • Tennessee Tech • Faisal Hossain • NASA at GSFC • Bob Adler • SSAI at GSFC • George Huffman

  3. Global Precipitation Measurement (GPM) • Launch: June 2013 • GPM will initiate the measurement of global precipitation, a key climate factor

  4. Hydrologic Modeling System (HEC-HMS)

  5. Final DSS HEC-HMS FIT

  6. General Data Flow Diagram

  7. Questions to answer in RPC • Which option is more appropriate: • an error propagation • a probabilistically downscaled? • How much to downscale? • Which product is more beneficial? • What are the implications?

  8. Location of basins • Upper Cumberland River, TN • Upper Yazoo Basin, MS • Lower Pearl River, MS

  9. Upper Cumberland River basin

  10. Upper Yazoo River basin

  11. Event Selection

  12. Earth System Models: • Army Corps of Engineers HEC-HMS model • Spatial analysis algorithms • Benefits: • Identify water supply demands • Now-casting of real-time flooding events • Flood hazard assessment • Asset Management and flood mitigation • Decisions Support: • HAZUS-MH (FEMA) • Predictions and Measurements: • Event/Seasonal runoff for modeled basins • Point specific hydrographs • Flood water extent • Earth Observations: • GPM proxy data

  13. Current Progress • Upper Cumberland River • HEC-HMS calibrated • TMPA data obtained from GSFC • Upper Yazoo River • HEC-HMS geometry validated • Dates selected • Lower Pearl River • HEC-HMS geometry being assembled

  14. Schedule

  15. Why these basins ? • Each is within different climate zones as defined by the NEON project • Each represent differing geology and topology • Upper Cumberland River, TN • mountainous • Upper Yazoo Basin, MS • low land interior • Lower Pearl River, MS • coastal
