SWMM5 EA by Assela Pathirana

SWMM5 EA is a simple application to demonstrate how genetic algorithms can be used to solve optimization problems in the field of urban drainage. Typical problems it can solve include: Find the optimal pipe/channel sizes for a drainage network to handle a flow of a given magnitude. Sizing of SuDS systems for the same purpose. Cost-benefit optimization of interventions.

SWMM5-EA Versions

• Version 5.1.0.102 released to fix a bug in version 5.1.0.10. Do not use 5.1.0.10. It has compatibility problems.

SWMM Versions

US-EPA the author of the excellent SWMM software, has the annoying practice of removing old SWMM binaries each time they publish a new SWMM version. Old SWMM versions are not forward compatible in a straight-forward way. In order to avoid frustration, I am compelled to keep the newest SWMM binary that is compatible with SWMM5-EA for download. Download the swmm version from https://github.com/asselapathirana/swmm5-ea/releases .
