The mathematical model of rainwater catchment in Wroclaw

On the basis of field studies of canalized storm water catchment of Gaj and Tarnogaj estate in Wrocław the rules of construction of hydrodynamic models in SWMM program were presented. The process of identification of hydrological and hydraulic parameters of the model, in the course of its calibration and validation were presented. To assess the quality of model the rates and statistical criteria were proposed to compare the results of stream simulation and volume of runoff of effective precipitation with the results of the measurements
