URBAN STORM RUNOFF MODEL

A surface flow routing model based upon a kinematic cascade of planes and channels is combined with a parametric infiltration model to constitute a watershed model. The kinematic approximation is used to route flows through storm drains of trapezodal or circular cross section. Model parameters are estimated from the hydraulic characteristics of the surface and soils. A Chezy friction relationship is used to model surface flow resistance. The predictive ability of the watershed model is tested by simulating runoff hydrographs from a 67-ha urban watershed near Denver, Colorado. /Author/
