    • Design and analyze culverts
    • StormCAD overview
    • Design and analyze culverts
  • 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 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.​
