Who it's for

  • Municipal engineers responsible for storm and sanitary sewers
  • Site and land-development designers sizing drainage and ponds
  • Consultants modelling runoff, surcharge and low-impact development

Draw it. Run it. See it.

  1. Draw it. Build the model on a real map, over aerial imagery, terrain and your GIS and CAD layers.
  2. Run it. Run the analysis from inside CIVILDRAW Storm.
  3. See it. Read the results on the map, in profiles and time series, and in reports.

What CIVILDRAW Storm does

Networks on the map

Draw conduits, junctions, storage, outfalls and subcatchments over the site, or build them from GIS layers.

Design tools

Size conduits, apply the Rational Method and create subcatchments directly from terrain.

Rainfall and runoff

Model rainfall, infiltration, runoff and low-impact development controls.

Results where you need them

Flows, depths and surcharge on the map, hydraulic grade line profiles and a full report.

Your existing models

Import and export .inp model files, so existing models come straight in and go straight out.

Scenarios

Compare design alternatives in one project.

Engine and files

Runs the EPA SWMM 5 engine, included.

Projects are saved as a single .cdstorm file.

HEC-RAS and HEC-HMS are developed by the U.S. Army Corps of Engineers Hydrologic Engineering Center.

CIVILDRAW is an independent product and is not affiliated with, sponsored by or endorsed by USACE, HEC, EPA or Open Water Analytics.

Questions

Yes. CIVILDRAW Storm imports and exports .inp model files, so existing models come in and go back out.

No. The hydraulic engine is included with CIVILDRAW Storm.
