About Stormwater Studio

Welcome and congratulations for choosing Stormwater Studio. This state-of-the-art desktop application features comprehensive storm sewer network modeling utilizing the most popular agency accepted computational methods along with automated design features. All this wrapped around a rich user interface built from the ground up with Windows Presentation Foundation.

Stormwater Studio was developed primarily for practicing civil engineers and related professionals involved with urban and rural storm drain modeling and design.

What you can do with Stormwater Studio

  • Interactively design entire storm sewer systems
  • Analyze new and/or existing storm sewer systems
  • Model storm sewer pipes and open channels
  • Comprehensive inlet design and analysis
  • Compute hydraulic and energy grade lines
  • Produce production-ready profile drawings
  • Produce professional looking, agency-ready reports
  • Integrate your designs with a variety of Cad programs
  • Work in U.S. Customary or Metric units

Technical Highlights

  • Models new and existing systems
  • Computes true energy-based Hydraulic Grade Line (HGL)
  • Optionally balances Tc with HGL
  • Handles partial, full and surcharged flow regimes automatically
  • Use widely accepted Rational method or specify your own Q’s
  • Computes Tc and rainfall intensities automatically
  • Develops IDF curves with 8 customizable return periods
  • Imports rainfall data from NOAA Atlases for IDF curve generation
  • Computes composite runoff coefficients
  • Computes full flow capacities
  • Computes junction losses in accordance with the latest HEC22, third edition, 2009
  • Computes junction losses using AASHTO method
  • Over 20 user-defined design constraints
  • Models circular, elliptical and rectangular pipe sections
  • Models trapezoidal, rectangular and v-shaped open channels
  • Models and/or designs 9 junction/inlet types with user defined defaults including
  • Curb, grate, combination and drop inlets with compound cross-slopes and individual local gutter depressions
  • Models headwall structures with overtopping weirs and various inlet edge options
  • Models flow diversions (Split flows exiting a junction)
  • Integrates utility crossings in your model to identify possible conflicts
  • Automatically computes inlet bypass, carryover flows, along with separate gutter and inlet spread widths
  • Bypass flows can be directed off site or to any other inlet in the project including upstream inlets and other systems
  • All inlet calculations comply with Federal Highway Administration (FHWA) Hydraulic Engineering Circular 22 (HEC-22)
  • Imports and exports system layouts from DXF and LandXML files
  • Imports LandXML, DXF and most image files as background images
  • Imports working TIN Surfaces from your CAD software for automated RIM elevation data entry
  • Much more!

Output Features

Professional reports are tabulated and include Standard DOT-style, HGL/EGL Calculations, Inlet tabulation and two User-defined reports. Each are exportable to .txt or .csv file formats. Other reports include plan views, inlet/surface drawings, and multi-line profiles. Includes Print Preview.
