摘要

A technique of state variable modeling has been applied to analyze two major phases of the urban water resources system. The first phase is based upon a lumped mathematical model to describe unsteady, nonuniform sewer flow in terms of a set of first order ordinary differential equations. This model can be used to route urban storm water through multi-level branching sewer networks. The model is compared with other routing techniques through the use of an example sewer network. For the second phase a nonlinear hydrologic system model has been formulated in the state variable form. Hydrograph analysis in conjunction with optimization search technique is performed to thirty seven rainfall storm events, in the period of fifteen years on a watershed in order to examine how the model parameters vary with levels of urbanization. Statistical analysis is used to suggest general trend equations for the model parameters.
