Near Real-Time Streamflow Simulation for Salt Creek in DuPage County, Illinois
in cooperation with DuPage County Stormwater Management Division
THE NEAR REAL-TIME OPERATIONAL FLOOD SIMULATION SYSTEM will improve the hydrologic information available in Du Page County for issuing flood warnings and optimizing the operation of the Wood Dale-Itasca and Elmhurst Quarry Flood Control Reservoir. The project has two major components: (1) the installation and operation of a comprehensive raingage network that will provide real-time rainfall data and (2) the development of a near real-time flood-simulation system. The objectives for the second component are: (1) simplify and interface the FEQ and HSPF models of the Salt Creek watershed into a near real-time flood-simulation system with greater robustness and ease of use; (2) test the modified models with fully routed simulation results and field data to ensure that the models are applicable; and (3) integrate the models with the data-retrieval and analysis systems being developed for the radio-telemetry raingage network with pre- and post-processors to ensure that the models are user-friendly and produce timely results. The flood-simulation system also may be applied with forecasted rather than collected rainfall data to allow more time for evaluating alternate flood-mitigation structure operation. The system will increase the efficiency of all Du Page County hydrologic and hydraulic modeling applications.
