StormNET automates your highway drainage design work. StormNET can simulate dual drainage systems (stormwater sewer network and city streets as dual conveyance pathways) and inlet capacity. It will quickly determine the amount of stormwater flow that is intercepted by the stormwater network inlets and the amount of stormwater flow that bypasses and is then routed further downstream to other inlets.

Leverage your AutoCAD® Land Desktop (LDD) and Civil 3D platform, by seamlessly sharing stormwater sewer design data with StormNET. Update a pipe size, invert elevation, sump elevation, or rim elevation, and have the updated change automatically reflect in the AutoCAD drawing. This sophisticated level of integration allows you to greatly increase your level of productivity.

Included with StormNET is an integrated Hydraulic & Hydrology (H&H) Toolbox, allowing you quick access to standard hydraulic and hydrology calculations. The H&H Toolbox makes it easier than ever to quickly perform engineering computations that drainage engineers commonly run into. Capabilities include:

• Design and analyze detention pond discharge structures, including compound weirs, multi-port risers, orifices, etc.
• Design outlet discharge aprons
• Design and size culverts, pipes, ditches, open channels
• Design and size stormwater inlets
• Design riprap protection
• And much more…
