StormNET automates your detention pond designs, eliminating the time-consuming process of iterating the pond design process.
- Automated detention pond design will save you hours of manual calculation time
- Size and design a detention pond in just minutes
- Easily compare pre- and post-developed hydrology conditions
- Perform interconnected pond routing
- Submit agency-ready reports
- FEMA approved
Automated Pond Sizer and Pond Designer
Designing a detention pond and outflow structure is one of the most difficult and time-consuming aspects of stormwater engineering. StormNET’s automated Pond Sizer and Pond Designer guide you through the process of sizing and designing a detention pond—allowing you to complete the process in just minutes!
- Automatically size detention pond, including required safety ledge and freeboard
- Specify maximum outflow rate and have the Pond Designer size your outflow structures for different frequency storms
- Quickly iterate in sizing and designing outflow structures for multiple storm events
- Account for tailwater submergence conditions
- Check design for multiple storm events for maximum outflow, storage, water surface elevation, and available freeboard
Model Simple to Complex Detention Ponds
StormNET can handle simple to complex detention pond designs.
- Handles single pond, multiple ponds, and interconnected ponds
- Provides constant feedback on how the detention pond design is progressing
- Uses industry-standard FHWA Hydraulic Design Series in performing its outlet calculations
- Handles variable tailwater conditions, including tailwater submergence effects
- Models ponds with multiple outlets and flow diversions
- Supports complex outlet structures, including
- Inlet boxes
- Multiple orifices
- Multi-port risers
- Compound spillways
- Culverts
- User-defined outflow structures
Pond Sizer Options
StormNET can automatically size the detention pond based upon your criteria.
- Generates table of different pond footprint sizes for different pond depths
- Accounts for safety ledge, different interior slopes, freeboard, aspect ratio
- Automatically checks your pond grading plans to meet required storage volume required for multiple storms
Underground Stormwater Detention and Infiltration
On-site, underground stormwater retention/detention can be incorporated into your StormNET model. Subsurface vaults or systems of large diameter interconnected storage pipes, arched pipes, or manufactured storage chambers can be modeled. StormNET includes standard storage chambers from leading manufacturers. Simply select the storage chamber model from a selection list, define the quantity, backfill dimensions, stone void space, and go!
Infiltration Basins and more
StormNET can model infiltration basins, accounting for both pollutant removal and reduction of stormwater released from the basin. In addition, wet and dry retention ponds can be modeled.
