SWMM-Based Urban Storm Sewer System Modeling

Abstract:

SWMM modeling plays an important role in the urban drainage system management. The paper depicts several modeling steps, including model parameters, dynamic wave options, CFL condition and equivalent pipe and model evaluation. For dynamic wave options, combination of ignore and both is relatively better than others. Impact of friction equation is very tiny. Especially, Froude No. is recommended not to use, while slope can make a good result. For inertial terms, ignore is considered as the best option. Equivalent pipe is used to deal with SWMM numerical instability, and coefficient of correlation, Nash-Sutcliffe efficiency are used to assess modeling performance.
