URBAN STORM WATER CONTROL EVALUATION WITH ANALYTICAL PROBABILISTIC MODELS

Methodologies for the development of analytical tools for screening level analysis of urban storm water runoff control. Models are developed with derived probability distribution theory, based on which the probability density functions of the rainfall characteristics of the urban drainage system (event volume, duration, intervention time) are mathematically transformed by a modified version of the rainfall-runoff transformation to yield system performance measures (volume of spills, number of spills, runoff capture efficiency). Comparison with continuous simulation results on a case study.
