Flood Assessment System for TxDOT (FAST)

The Texas Department of Transportation (TxDOT) wishes to move from a reactive to a proactive response during flood emergency operations. Real-time flood map services provide valuable information for TxDOT flood decision making. The National Weather Service initiated the operation of real-time flood inundation maps for Texas in October 2023. The research team will create a Flood Assessment System for TxDOT as an additional set of real-time flood maps to describe flood impact on the road and bridge system. These maps will be distributed to TxDOT's Maintenance Division staff as web services and tested in large scale flood emergency response exercises conducted with TxDOT Districts. The research team will operate and maintain 80 RQ-30 stream gages to support flood forecasting and decision making. Researchers will refine the targeted approach for RQ-30 velocity sensor calibrations to support timely rating development using velocimetry. As many of the 80 RQ-30 gauges as possible will be added to the Interagency Flood Risk Management (InFRM) Flood Decision Support Toolbox. Combining novel gauging techniques with inundation mapping provides real-time streamflow information and transportation flood impacts that enable scenario planning and proactive actions to flood events. This project will be a continuation of Project 0-7095 "Evaluating Improved Streamflow Measurement at TxDOT Bridges."
