CivilStorm is a fully dynamic, multi-platform, hydraulic modeling application developed for the analysis of complex stormwater systems. Engineers can analyze these systems using built-in hydraulic and hydrology capabilities and a variety of wet-weather calibration methods. From stormwater master plan development to water quality studies, CivilStorm provides an easy-to-use environment for engineers to analyze, design, and operate stormwater systems.

CivilStorm takes advantage of Bentley CONNECTservices by associating a hydraulic model with a CONNECT project. This enables all team members to have easy sharing access to the model. One Solution for all Stormwater System Modeling Needs
CivilStorm performs comprehensive 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.Engineers can 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 their design, all within a single application.

Model in Stand-alone or Within Favorite CAD Platform
CivilStorm works as a stand-alone application, or can be run from within MicroStation or AutoCAD. Regardless of the platform used, CivilStorm maintains a single set of modeling files for true interoperability across platforms, support for multiple background layers, conversion utilities from CAD, GIS, and databases, and unlimited undo and redo.

Streamlined Model Building
Engineers can leverage geospatial data, CAD drawings, databases, and spreadsheets to jump-start the model building process. CivilStorm provides synchronized database connections, geospatial links, and advanced model-building modules that connect with virtually any digital data format. In addition, modelers can import SWMM files as well as StormCAD files into CivilStorm. CivilStorm also provides drawing and connectivity review capabilities to guarantee a hydraulically coherent model.

Easy Model Management with Scenarios
The Scenario Management Center in CivilStorm gives engineers full control to configure, run, evaluate, visualize, and compare an unlimited number of scenarios within a single file. Engineers can easily make decisions by comparing alternative designs or proposed rehabilitation methods for a variety of system conditions (including pre- and post-development).

Built-in Stormwater Hydrology
Engineers can load models with wet weather runoff flows derived from precipitation using the CivilStorm built-in rainfall distributions, or user defined rainfall events. Runoff flows are modeled using a choice of hydrograph methods,including RTK, SCS, Modified Rational, EPA -SWMM, or user-defined generic unit hydrographs.

Low Impact Development
CivilStorm can model the effect that low impact development controls have in retaining runoff before it enters the stormwater system.

Capabilities

Allocate and estimate stormwater loads
-Load models with wet weather runoff flows derived from precipitation using the built-in rainfall distributions or user-defined rainfall events. Runoff flows are computed using the most appropriate runoff method for the project.​​

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.
