DIMENSIONLESS INLET HYDROGRAPH MODEL

A number of mathematical models used to estimate storm hydrographs in urban areas consider runoff as a deterministic process and link a series of submodels to simulate the behavior of the various components of the runoff cycle. Because of the number of interrelated formulations in these linked system models, a large core computer is generally required for their proper use. The paper presents a dimensionless inlet hydrograph that can be developed from a complete linked system model and used as a substitute in some planning and design situations. The central objective was to develop a method for estimating the hydrograph for a small urban watershed entering in inlet or catch basin that would be simple enough to allow hand computations while retaining good agreement with the computer generated hydrographs obtained with a complete linked system model.
