Tutorial 01: Post-development Runoff in an Urban Catchment
Surface runoff from a 49-acre residential site is computed for several design-storm events under both pre- and post-development conditions.

Tutorial 02: Surface Drainage Hydraulics
A surface runoff conveyance network is added to the post-development catchment area of Tutorial 01 and is analyzed with GeoSWMM’s various hydraulic routing options.

Tutorial 03: Detention Pond Design
A detention pond and outlet structure are designed for the post-development condition of Tutorial 02 to meet both water quality control and peak flow reduction criteria.

Tutorial 04: Urban Flooding – 2D Model Simulation
This tutorial utilizes the GeoSWMM 2D model to explore flood extents in urban watersheds, providing a detailed analysis of surface water flow during large storm events.
