What is StormCAD?
StormCAD is a comprehensive modeling software for the design and analysis of storm sewer systems with unlimited inlets. With StormCAD, you can calculate catchment runoffs, inlet capacities, and gutters and pipe network flows.
Out of the box, you can employ this product as a stand-alone application or work directly from within MicroStation. StormCAD maintains a single set of modeling files for true interoperability across platforms. The stand-alone interface offers easy-to-use model layout tools, multiple background support including Bing aerial imagery, conversion utilities from CAD, GIS, and databases.
- Inlet and network hydraulics
StormCAD determines intercepted flow at network inlets, and routes bypass flow to selected bypass targets. Inlets can be computed using the U.S. Federal Highway Administration (FHWA) HEC-22 methodology and you can choose from grate, curb, slot, ditch, and combination inlet types. You can use a variety of methods to compute head loss, including HEC-22 Energy and AASHTO.
StormCAD solves for subcritical, critical, and supercritical conditions with its robust gradually varied, standard-step algorithm. StormCAD calculates friction losses using Manning, Kutter, Darcy-Weisbach, and Hazen-Williams, and you can choose circular, box, arch, or elliptical pipe section shapes or irregular, trapezoidal, or triangular channel sections.
- Hydrology and loads allocation
StormCAD uses the Rational Method to calculate peak flows in the storm sewer design, or accepts direct input of known flows for inlet inflows. StormCAD allows you to specify Intensity-Duration-Frequency data using equations or tables. You can then plot the IDF curves, and reuse the data for other projects in that region. You can also work with an unlimited number of sub-watershed areas and C coefficients for each inlet watershed. StormCAD allows the input of external contributing areas, additional flows, and carryover flows to model non-local runoff contributing to the discharge at any inlet. StormCAD provides several methods for computing travel time, including full pipe velocity, normal velocity, average end velocity, and weighted average velocity.
- Automatic design
The constraint-based design features in StormCAD allow you to automatically design gravity piping and structures. The design is flexible enough to allow you to specify the elements to be designed, from a single pipe size to the entire system, by simply entering the appropriate design conditions: minimum/maximum velocities; pipe elevation offsets (including whether or not to allow drop structures), maximum spread and depth for inlets in sag; and minimum efficiency for inlets on grade. StormCAD will automatically determine cost-effective pipe sizes and invert elevations while minimizing pipe cover to avoid unnecessary pipe trench excavation.
- Comprehensive scenario management
With StormCAD scenario management center, you can evaluate, visualize, and compare an unlimited number of what-if scenarios within a single file. You can easily make decisions by comparing design approaches with varying velocity, slope and cover restrictions, evaluating system capacity for multiple storm events, or analyzing outlet flow using different estimations for the catchment Rational Coefficients.
How do I use StormCAD?
You can learn how to use OpenFlows StormCAD by watching Bentley’s tutorial videos that showcase useful functionalities. Additionally, when you purchase through Virtuosity you get a Virtuoso Subscription which means you get both software and training or expert services you need to get started quickly.
How much does StormCAD cost?
A practitioner license of OpenFlows StormCAD costs $2,400 USD at Virtuosity.com. To see the price in your local currency, select your currency at the bottom of this page.
