A Tale of Three Cities In 2D

Waukesha, Wisconsin has stormwater flooding. Whitefish Bay, Wisconsin has both stormwater flooding and basement backups from separate sanitary sewers, and Lincolnwood, Illinois has basement backups from its combined sewers. A similar sewer system analysis approach that includes advanced one-dimensional and two-dimensional dynamic hydraulic modeling provided decision makers with the information with which to make long-term infrastructure investment decisions.For all three communities, the XP-SWMM 1D/2D models included a one-dimensional representation of the sewers and two-dimensional representation of the surface. XP-SWMM 2D provided the ability to simulate surface and subsurface flows and interaction thereof in a precise and fully dynamic manner. Capital improvement programs for Lincolnwood and Whitefish Bay have been prepared while Waukesha's is nearing completion.
