Curve Number - HydroCAD Stormwater Modeling

What is the Curve Number? Each subcatchment uses a Curve Number (CN) to characterize the runoff properties for a particular soil and ground cover. The CN value is a primary input parameter for the SCS runoff equation, as used by HydroCAD. High CN values (such as 98 for pavement) cause most of the rainfall to appear as runoff, with minimal losses.
