| LID Control Editor |
The LID Control Editor is used to define a low impact development control that can be deployed throughout a study area to store, infiltrate, and evaporate Subcatchment runoff. The design of the control is made on a per-unit-area basis so that it can be … Read the rest
LID Results - Summary Report
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 SWMM5. The SWMM's Output Modeling Report also contains a section entitled LID Performance Summary that provides an … Read the rest

This blog is a companion to the blog post https://swmm5.org/2017/04/17/swmm5-simple-100-mm-rainfall-model-for-lid-modeling-part-1/ in which a 1 Hectare model with 100 mm of rainfall had a simple Bio-Retention Cell with no LID outflows. In part 2 of this blog series we will add a drain coefficient of 10 mm/hr (Figure 1). The internal … Read the rest
