【讲座内容简介】

This presentation gives a brief introduction of CCHE2D/3D model system and its capabilities. CCHE2D/3D is a state-of-the-art numerical modeling system developed at the National Center for Computational Hydro-science and Engineering (NCCHE) at the University of Mississippi. The model targets simulating water resource and environment related problems. It is capable of simulating free surface river flows, flooding/dam-break flows, sediment transport, morphological changes, chemical pollutant transport, environmental water quality, hurricane and coastal storm surge and wave processes. Recently, this hydro-dynamic model has been extended to simulate the rain-induced overland flow. It is capable of simulating rainfall events on soil plots, small watershed, and urban areas. For soil erosion simulations, fixed-bed rainfall simulation is providing detailed flow fields to give general guides on the distribution of conservation measures. The mobile-bed rainfall simulation with splash erosion and sediment transport is under development. Since its initial development in the 1990s, it has been continuously developed and updated at the NCCHE and used by thousands of users in the US and worldwide. Many federal and state agencies have been CCHE2D users including USACE, USDA-ARS, NOAA, USGS, US Fish &Wildlife Service, USEPA, CA Dept. Water Res., Oak Ridge National Lab, North Alamo National Lab, US Navy Naval Oceanographic Office, US Marine Corps, Desert Res. Ins., National Disaster Preparedness Training Center, etc.
