Both ICM SWMM and ICM InfoWorks incorporate the EPASWMM's Low Impact Development (LID) or Sustainable Drainage Systems (SuDS) controls and Subcatchment features, offering a summary of LID inputs and outputs within the SWMM5 Report File (RPT file). These summaries provide an overarching view of the LID performance. However, they fall short of providing detailed time series results for the LID, which can significantly aid users in analyzing the flux rates and moisture levels throughout the simulation period for a selected LID control within a given subcatchment.
In EPASWMM, each subcatchment control's data is written to a separate file, which can be overwhelming in models with a large number of subcatchments. Contrarily, InfoSWMM consolidates all detailed LID information into a single file, making it more manageable and user-friendly. Users can easily sort and filter this file by control and subcatchment, enabling a more profound understanding of the LID water balance. This centralized file can be effortlessly imported into a spreadsheet program, facilitating easy viewing and graphing of data, thus providing a deeper insight into the inner workings of the LID's soil, storage, drain layers, among others. This comprehensive data provision, in a more consolidated manner, enhances the user's ability to analyze and understand the behavior and performance of LID controls within their models.and
