GeoSTORM vs. Civil 3D

GeoSTORM is a Civil 3D-integrated stormwater modeling software that streamlines catchment area delineation, runoff calculations, and flow routing. It supports multiple hydrology methods, such as EPA SWMM, SCS TR-55/TR-20, Rational, Modified Rational, and DeKalb Rational, enabling flexible hydrologic analysis. Capabilities include interactive detention/retention pond design and roadway catch basin optimization using major U.S. and Canadian foundry catalogs, which helps engineers move from concept to deliverable efficiently.

Autodesk® Civil 3D® is civil infrastructure design and documentation software that helps civil engineers design, analyze, and document transportation, land development, and water infrastructure projects in a 3D model-based environment. Civil 3D provides integrated tools for working with the data and design elements used throughout civil engineering projects. Engineers and designers can create and manage surfaces, alignments, profiles, corridors, grading, pipe networks, and other infrastructure design elements while maintaining relationships between objects as designs change.
