Abstract: This research validates the CCHE2D hydrodynamic model flood simulation results using a series of satellite imagery and several digital image processing techniques. Previously CCHE2D model simulation results have been validated using measured experiment and field channel flow data. In this study, remotely sensed data has been experimented to provide continuous truth data to evaluate the CCHE2D model simulation results for flood propagation due to levee breaching. Digital image processing based models were developed using satellite imagery acquired during the June 2008 US Midwest flood event and a time series of flood extent maps was generated for Alexandria, MO and Warsaw, IL areas along the Mississippi River. The flood maps were compared with the CCHE2D model simulation results and found in good agreement. This research shows that satellite imagery has the potential to provide continuous validation data for hydrodynamic models to develop and implement flood related emergency response plan.
