Model flood control structures such as detention basins with various outlet structures. Use actual or synthetic rainfall distributions. Import hydrographs or combine hydrographs at any point. Simplified user interface. Calculate flood and routed hydrographs using the TR-20 method.
More reports are available with user-defined custom formatting.
Display flow and volume quantities in a variety of units. A tabular rainfall entry method provides more accuracy when developing IDF curves. Rainfall maps now allow you to view the rainfall intensities for the area surrounding your state. Outlet structures and reservoirs can now be saved to a central library. With Watershed Modeling you can evaluate these and many other drainage design concerns.
