Rainfall data: PondPack can handle an unlimited number of synthetic or real storm events of any duration or distribution. Choose any standard and regionalized methods such as: SCS 24-hour Type I, IA, II, and III rainfall distributions, Bulletin 70 and 71 rainfall distribution data for the Midwest U.S., gauged rainfall data, rainfall curves created from I-D-F data, I-D-F curves, and more.
Infiltration and runoff computations: Choose from the SCS Runoff CN method, Green-Ampt equation, Horton equation, initial and average infiltration rates, user-defined infiltration equations, and more.
Time of concentration calculator: Calculate Tc quickly and accurately, even when there are several possible flow paths to consider. Set up different "what-if" situations for various assumptions to remove the guesswork in finding the most representative Tc, or directly insert your own value.
Peak flow and hydrograph methods: Use the SCS Graphical Peak Discharge method, the rational method, or generate and add an unlimited number of hydrographs throughout your watershed.
