GeoSTORM

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.

MODRET is an easy-to-use interactive computer program that calculates unsaturated and saturated infiltration losses from stormwater retention/detention ponds in unconfined aquifers using a modified version of MODFLOW. Other unique capabilities include: Generation of single watershed stormwater runoff hydrographs using SCS unit hydrograph, Rational and Santa Barbara urban hydrograph methods with graphical display of the results. Routing of runoff hydrographs (MODRET-generated and/or others) through infiltration losses of ponds and generation of infiltration routed hydrographs. Specification of overflow devices (weirs, orifices and rating curves) for the stormwater retention/detention ponds and calculation of total volume and peak discharges. Generation of ground-water elevation cross-sectional graphics with ZOOM capabilities. Generation of XYZ data files which can be used by other programs (SURFER, AutoCAD, etc.) to generate groundwater contour maps and 3-D surfaces.
