A typical hydrologic study, including city-wide master plans of drainage, require different regulatory flood levels according to storm event return frequency. For example, one may target that streets have storm flow contained below street top of curb for a 25 year event whereas one traffic lane is kept open for a 5 year event.
BUTTON 3 executes the hydrology model for the variety of return frequency storm events specified by YOU, and according to the street flow depth requirements specified by YOU. These results are then used for existing system deficiency analysis, and other study modeling inputs.
