Development and Calibration of a Hydrologic Model for the Wichita Falls District
Project Proposal
GIS in Water Resources (394K.3)

Geographic information systems (GIS) tools have been developed by the Center for Research in Water Resources (CRWR) at the University of Texas at Austin to assist in the design of highway drainage facilities. Design of these structures involves hydrologic analysis to determine parameters such as design discharge and conveyance capacity. Currently, data input to hydrologic software packages is a very expensive and time consuming process. GIS has proven to reduce analysis time and improve accuracy in design of these facilities.
In this project, I will use these GIS tools to develop and calibrate a hydrologic model for a Texas Department of Transportation (TxDOT) highway drainage site in the Wichita Falls district of Texas.

The following information is necessary to develop and calibrate a hydrologic model for the Wichita Falls district:
1. 30-Meter Digital Elevation Models (DEM's)
2. Stream Networks in National Hydrography Dataset (NHD) Format
3. Curve Number Grids
4. Road Coverages
5. USGS Flow and Stage Data; and
6. Precipitation Data
|
1. Contacting TxDOT
2. Data Collection
3. DEM-based Hydrologic Model Development using CRWR-PrePro
4. Hydrologic Model Calibration

This project will be based on results from Dr. Francisco Olivera's and David Anderson's research. David Anderson's work focused on the Castleman Creek watershed in McLennan County, and Pecan Bayou watershed located in Brown County.
