MARYLAND HIGHWAY DRAINAGE STUDY. VOLUME V. A DIMENSIONLESS HYDROGRAPH FOR ESTIMATING STORM RUNOFF FROM URBAN AREAS
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 inter-related formulations in these linked system models, a large core computer is generally required for their proper use. The report 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 entering an 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.
