Modeling a Campus Sub-basin With HEC-HMS Progress Report Modeling a Campus Sub-basin With HEC-HMS

Developments Original project idea scrapped Selected new study area Difficult to find adequate GIS data No measured flow data to validate model results Selected new study area

New Area

Area Characteristics Located on UT campus at 24th and San Jacinto Dr. Barrett has a monitoring point at basin outlet Have access to a great deal of rainfall and runoff data

Goals Create terrain model in Arcview Process terrain model with HEC-geoHMS Create working hydrologic model in HEC-HMS Calibrate model and evaluate results with measured rainfall and runoff data

Current Progress Defined new project Acquired GIS data Creating terrain model in Arcview

Data TINs developed by Azagra and Tate One-meter DEM developed by USGS (courtesy of Becky)

Interesting Questions Which data source is best suited for this application? How can we use HEC-geoHMS? How can we create a hydrologic model a restricted basin in a meaningful way? How will this model interact with other models created in the area?
