Modeling Catchbasins and Inlets in SWMM

As of late, modeling of urban drainage systems is often comprised of both the major and minor systems. Representing the inlet capture functions is of key interest when modeling dual drainage systems in SWMM. Matthew Senior, Ron Scheckenberger, and Brian Bishop from Amec Foster Wheeler describe various methods of modeling these functions and assesses them under different conditions, using models that had been developed for several urban communities in the most recent JWMM paper. The relative benefits and drawbacks of each method are given and discussed, along with associated considerations for minor and major system design in dual drainage modeling. Read the full article:
