Subcatchment Manager

The painstaking task of analyzing contour maps to delineate Subcatchment used to devour time and money for engineers performing stormwater design projects. With the advent of the InfoSWMM Suite, engineers can drastically reduce the time it takes to develop and interpret continuous hydrology and dynamic hydraulic simulations.

InfoSWMM Suite is specially designed to utilize digital topology data to define Subcatchments and calculate their hydrologic parameters.

InfoSWMM Suite allows users to delineate Subcatchment boundaries based on Digital Elevation Models (DEMs), contours, TINs, or point elevation sets. Subcatchment delineation can then be easily verified with the overlay of aerial photography or other background information. The InfoSWMM Suite also includes tools to augment Subcatchment boundaries and easily connect Subcatchments to the appropriate raingages and outlets.

The automation of Subcatchment delineation and parameter calculation allows water resources engineers to apply their time to evaluating solutions instead of performing drudgery. Subcatchment Manager uses advanced processing to prevent delineation of very small subcatchments and vastly increase the accuracy of subcatchments delineated from man-made collection point locations. Subcatchment information such as area, width and slope are easily calculated based on the underlying topology. Other hydrologic parameters such as impervious area and infiltration rates can be quickly inferred from the available GIS data for land use and soil types. The seemingly endless recalculation of parameters every time a Subcatchment boundary is changed is now as easy as clicking a button.
