Low Impact Development (LID) is a term used to describe green infrastructure designed to intercept, store and/or infiltrate precipitation before it reaches the conveyance system. LIDs are becoming an increasingly popular alternative to "end of pipe" solutions and an integral part of new development designs and retrofits. Modeling LIDs provides insight into the processes within a proposed LID, allowing for design optimization and “what-if” comparisons.

This workshop provides an in-depth look at green infrastructure (LID) modeling capabilities in EPA SWMM5/PCSWMM. Learn about the theory behind the eight types of LIDs in the SWMM5 LID module, how to implement LIDs in a model, and how to analyze the model results. The workshop will also discuss possible ways of modeling LIDs that are not included in the SWMM5 LID module and how to use other tools, such as Python scripting and control rules, to set up LIDs in a model.

Participants will develop the necessary skill and confidence to explore and apply the official EPA SWMM5 hydrology/hydraulics engine effectively in a LID modeling capacity.

PCSWMM will be used throughout the workshop to speed learning and program execution, and to enhance the understanding of the underlying EPA SWMM5 LID processes. During this course you will have an opportunity to learn from a live instructor during scheduled live sessions.

You will receive full workshop details prior to the workshop. If you have any questions or comments, please contact our workshop coordinator.
