Stormwater Runoff Calculator. Sequential Runoff Method A series of runoffs is held, eliminating the candidate with the fewest first place votes at each stage. The runoff and rainfall can be linked with runoff coefficient. They do this by using characteristics for various types of weather such as high-intensity, short-duration rainfall that may occur in regions in many parts of the world. If you have a previous version installed, you must uninstall it before installing the update. Include the pond's area within one of your subcatchments, or set up a separate subcat with a Tc of zero and a CN of 98-100. It estimates the amount of stormwater runoff generated from a site under different development and control scenarios over a long-term period of historical rainfall. The Curve Number Calculator comprises four tabbed pages that are used in a sequential manner. For installation problems, contact your system administrator.
