Abstract
As part of an overall storm water management program, a model was developed to simulate the runoff phenomena of a drainage basin for any given rainfall pattern. The model represents the basin by an aggregate of idealized subcatchments and gutters. The computer is instructed to make a step-by-step accounting of rainfall, infiltration, detention, overland flow and gutter flow in the calculation of a hydrograph. Three preliminary simulations are made to demonstrate the validity of the method.
