Description from store
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
