Calculating the Quantity of Storm-Water: 2 Methods | Sanitary Engineering

Generally there are two methods by which the quantity of storm-water is calculated: 1. The Rational Method 2. Empirical Formulae Method. In both the above methods, the quantity of storm water is a function of the area (in hectares): the intensity of rainfall and the coefficient of runoff. The coefficient of runoff or the maximum rate of runoff mainly depends [...]
