GeoSTORM

GeoHECHMS greatly speeds up the creation, analysis, and review of stormwater models. It is a data wrapper to the industry-standard US Army Corps of Engineers HEC-HMS software using an AutoCAD compatible graphical user interface. GeoHECHMS offers: • Automated HEC-HMS Workflows • AutoCAD Civil 3D & ArcGIS Integration • Automated Watershed Delineation • Detention Pond Design • Purpose-Built Stormwater Design Tools • Automated TOC & Lag Time • Automated CN Computations • Comprehensive Report Generation GeoHECHMS lets you quickly compare different scenarios and alternatives, such as pre-development conditions with different post-development designs. Rapidly construct, design, analyze and compare detention and retention ponds.

Comprehensive stormwater modeling and analysis software. Stormwater systems can be very complex to model, with flow backups and reversals, surcharged pipes, and more. OpenFlows CivilStorm is one solution for all your stormwater modeling needs. Detect system bottlenecks, improve capacity, and limit stormwater flooding, so you can comply with stormwater regulation . Minimize capital investments on your infrastructure with optimized network designs and master plans for your entire system. OpenFlows CivilStorm performs analysis of all aspects of stormwater systems: rainfall, runoff, inlet capture and bypass, gravity and pressure piping, ponds, outlet structures, open channels, culverts, and more. It provides comprehensive stormwater modeling. Analyze pressure and free-surface flow conditions for networks of channels and closed conduits; model complex pond outlets for a variety of tailwater conditions; and use weirs, orifices, culverts, risers, and inlet boxes in your design.
