Description
Perform common stormwater calculations quickly using Rational Method, Tc, and Detention Volume tools. StormCalc is your all-in-one toolkit for stormwater and dam volume calculations. Designed for civil and hydraulic engineers, consultants, and field practitioners, this tool streamlines common hydrological calculations into a single, easy-to-use Chrome extension Features: Rational Method: -Quickly estimate peak flow (Q) using runoff coefficient, intensity, and area. Time of Concentration (Tc): -Calculates Tc using the Bransby-Williams method with flexible unit inputs. Detention Volume Calculator: -Compares pre- and post-development scenarios with auto-generated hydrograph and required detention storage. Manning’s Equation (NEW): -Computes flow rate for both circular and rectangular pipes with built-in roughness coefficients. Dam Volume Estimators: -Quick Method -Square Dam -Circular Dam -Gully Dam
