Developing a Radar-based Flood Alert System For Sugar Land, Texas
Bedient, Philip B.
Master of Science
This thesis presents a framework for a radar-based flood alert system (FAS) for the Oyster Creek Watershed to aid the City of Sugar Land in flood forecasting. The motivation for using this particular system stems from a radar's ability to provide flood warning lead-time when calibrated with available gauge information. This study follows a typical workflow in analyzing watersheds, which involves converting excess rainfall to runoff, then converting the resulting flow rates to polygons that show water levels. This thesis also introduces the Flood Warning Indicator (FWI) as a component of Sugar Land's FAS. FWI only uses radar rainfall to portray potential flooding problems within the watershed through GIS mapping, which is helpful when gauge information is unavailable. Having a significant role in the communication of flood information, FWI may be applied in other areas that lack the resources to build extensive gauge networks for flood monitoring and radar calibration.
