A comprehensive system for modeling hydrology, hydraulics, and water quality. Get the full picture for all scenarios.

Smarter stormwater and flood modeling

Stormwater and Watershed Management

Simulate rainfall-runoff, pollutant build-up, wash-off, and routing using best-in-class modeling technology and design your stormwater infrastructure all from an ArcGIS-integrated modeling environment.

Stormwater and Watershed Management
Quick, Interactive Model Building

Quick, Interactive Model Building

Drag and drop your GIS data for subcatchments, pipes, and other components into the model, and GeoSWMM will lead you through a rich set of tools to simplify model building tasks.

Maintain Model Integrity Long Term

Maintain Model Integrity Long Term

By using GeoSWMM, you can reduce data redundancy and errors while improving data security, consistency, and access.

Modeling for the Real World

Modeling for the Real World

GeoSWMM delivers a realistic representation of the physical world, avoiding common pitfalls and disjointed analyses of hydrology and hydraulics.

Dual Drainage Systems

Urban flood resilience depends on well-designed and well-maintained dual drainage systems. GeoSWMM helps optimize above and underground conveyances to minimize flood risk.

Build Complex Models with Ease

Build Complex Models with Ease

GeoSWMM's interactive model-building process captures the real-world complexities of parameterizing a coupled surface and underground hydraulic system model.

Surface Flow Path Generation

Surface Flow Path Generation

Storm sewer overflows often follow undefined flow paths. Use GeoSWMM to identify these flow paths and mitigate flooding.
