OpenFlows CivilStorm

All-in-one stormwater management

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 regulations
Minimize capital investments on your infrastructure with optimized network designs and master plans for your entire system.

Capabilities

Allocate and estimate stormwater loads
- Load models with wet weather runoff flows derived from Hydro-35 or Intensity-Duration-Frequency rainfall events. Runoff flows are computed using the Rational Method.
Analyze inlet capacities
- Calculate the proportion of stormwater runoff that will enter an inlet versus the proportion that will be carried downstream in a gutter or pond on the road surface. Quickly confirm that the spread of flow in a gutter doesn't exceed design requirements.
Build and manage hydraulic models
- Jumpstart the model-building process and manage your model effectively so that you can focus on making the best engineering decisions. Leverage and import many well known external data formats, which maximizes ROI on geospatial and engineering data and automates input data generation.
Design and analyze culverts
- Select from a library of standard culvert shapes, materials, and entrance conditions, then compute culvert headwater and tailwater elevations using calculation methodologies outlined in Hydraulic Design Series Number 5 from the U.S. Federal Highway Administration.
Design and analyze low impact development controls
- Model the effect that low impact development controls have in retaining runoff before it enters the stormwater system.
Design and analyze pond and outlets
- Leverage PondMaker's guiding process through the confusing maze of pond design steps by following the step-by-step process that provides constant feedback on how the design is progressing. Set the maximum outflow rate, estimate storage, and check the outlet design and final design.
Design stormwater systems
- Minimize capital investments by simply entering your design restrictions: velocities, slopes, cover depths, and pipe and inlet matching offsets. The software product recommends the most cost-effective pipe sizes and invert elevations, avoiding unnecessary pipe trench excavation, while meeting design restrictions.
Simulate hydraulics using multiple solvers
- Easily switch among multiple solvers according to the type of system you are analyzing: Saint Venant equations and rational/gradually varied flow solver.
Simulate water quality
- Simulate the generation, inflow, and transportation and treatment of any number of user-defined pollutants, such as total suspended solids or heavy metals.
