The City of Atlanta recently completed a project that analyzed the hydrologic and hydraulic conditions of their combined sewer system during overflow conditions (large wet weather events) and included an evaluation using a surface flow model dynamically linked to the closed pipe system to estimate surface flooding depths and develop flood inundation mapping for the City. For this project, flood analysis of combined sewer overflow (CSO) models were created by incorporating ground surface and other topographical features using the InfoWorks software, which includes a 2-dimensional surface flow routing module capable of analyzing hydraulic interactions between the pipe network and conveyances across the overlying ground surface. The end result was the development of a set of flood maps to support the City's planning efforts and helps guide new development near flood-prone areas within the combined sewer system service areas.
