LID Results

The performance of the LID controls placed in a subcatchment is reflected in the overall runoff, infiltration, and evaporation rates computed for the subcatchment as normally reported by GeoSWMM. GeoSWMM’s Summary Report also contains a section entitled LID Performance Summary that provides an overall water balance for each LID control placed in each subcatchment. The components of this water balance include total inflow, infiltration, evaporation, surface runoff, drain flow, and initial and final stored volumes, all expressed as inches (or mm) over the LID’s area.

Optionally, the entire time series of flux rates and moisture levels for a selected LID control in each subcatchment can be written to a tab delimited text file for easy viewing and graphing in a spreadsheet program.
