Title: Integration of Global Precipitation Measurement Data Product with the Hydrologic Engineering Center-Hydrologic Modeling System


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
  • MRCRPC team
  • Lance D. Yarbrough and Joel S. Kuszmaul
  • Tennessee Tech
  • Faisal Hossain
  • NASA at GSFC
  • Bob Adler
  • SSAI at GSFC
  • George Huffman
  • University of Connecticut
  • Amvrossios C. Bagtzoglou

3
Objectives
  • Integration of satellite rainfall data into
    HEC-HMS
  • How far can satellite data be downscaled?
  • What NASA products are the most effective for
    estimating rainfall?
  • Can we connect HEC-HMS with HAZUS?

4
Uncertainty of Simulated Streamflow Using SREM2D
at Native Scale (0.25)
3B42 Precipitation Data versus Streamflow
5
Tasks
  • Calibrate HEC-HMS model for basins in the study
  • Complete comparison of results for all three
    basins

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

Event Selection
14
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

15
Conclusions
  • Cumberland and Upper Yazoo complete
  • Pearl River modified to minimize coastal
    influence
  • Models calibrated and completed
  • Two articles on rainfall simulation published
  • 3B42 product bette
