Existing RSM Models Goal – to simulate the distribution in space and time of hydraulic head and water flow in surface water, shallow groundwater and SWFFS canal systems under alternative management policies. Time horizon is in daily time steps summarized monthly Southern Everglades continuing for years North Palm Beach South Dade

Multipatch A multipatch is a volume built by joining surfaces. Each layer is a set of multipatchs developed from the original triangular mesh DEMO: ODSSMESH. mxd Multipatchfor. ODSS. sxd

Flood Modeling and Managment • Goals: – Flood management in the District – Flood evaluation for CERP – Flood mapping for FEMA • C-4 Basin is a sample study region C-4

C-4 Basin • Drainage areas defined within basin • More structures • Same base hydro network • Flood simulation models in XP-SWMM • Short time horizon of events (~ 3 days)
