OpenFlows CivilStorm

Stormwater Modeling and Analysis Software

All-in-one stormwater management

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.

What is OpenFlows CivilStorm?

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. 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.

    One Solution for all Stormwater Modeling

    Flexible Storm and Runoff Calculations

    Use a wide range of storm data formats including a simple table of depth vs. time, methods based on intensity/duration/frequency tables and curves, to Hydro-35 or special regional hydrographs.

    Low Impact Development (LID) Controls

    Leverage tools that help evaluate best management practices such as porous pavement, rain gardens, green roofs, vegetated swales, and rain barrels.

    Design Stormwater Systems

    Minimize capital investments by simply entering your design restrictions: velocities, slopes, cover depths, and pipe and inlet matching offsets. Find out the most cost-effective pipe sizes and invert elevations, avoiding unnecessary pipe trench excavation, while meeting design restrictions.

    Performs analysis of all aspects of stormwater systems

    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.

    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.

One-time purchase with support

Perpetual License with SELECT

A perpetual license of Bentley software is a one-time purchase, with a yearly maintenance subscription, called SELECT. This includes 24/7/365 technical support, learning resources, and the ability to exchange licenses for other software once a year. With SELECT, you will benefit from:

  • License pooling, so you can access your software from multiple computers.
  • Access additional Bentley software with Term Licenses, which allow you to pay for what you use without the upfront cost of purchasing a perpetual license.

Annual renewal quotes are delivered directly to your inbox, and our experienced Renewal Representatives are available to answer your questions and guide you through any changes you’d like to make.
