# GeoSTORM Discussions

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. Additional features include cloud-based mapping, 2D/3D model visualization, and in-depth automated report generation. GeoSTORM is engineered for both urban and rural stormwater drainage systems, supports scenario comparisons, and accelerates design review and iteration, making stormwater workflows faster and easier to maintain.
