Overview of a Real-Time Flood Management Model

Document Type: Proceeding Paper

Part of: Engineering Hydrology

Abstract:

A flood management model was developed for the operation of the six reservoirs making up the Highland Lakes System on the Colorado River in Texas. The model allows simulation of over 700 total river miles, which includes three major and one minor tributary along with the mainstem, discretized by some 500 cross-sections. The system, operated by the Lower Colorado River Authority (LCRA), is characterized by sharply rising flood hydrographs. The base model was developed by the University of Texas in Austin. LCRA has further modified the model to include features to better simulate the reservoir system. The model uses data obtained by a hydrometeorological collection system.
