Updating Culvert and Storm Drain Design and Installation Methods

WMS and the HY12 Stormwater Model Interface

The Watershed Modeling System is produced by Aquaveo to automate hydrologic and hydraulic models, including 2D distributed hydrology. WMS performs hydraulic modeling, floodplain mapping, and storm drain modeling. Watershed data collection has never been easier to collect than with web-based data tools in WMS. Aquaveo now has subscription pricing for WMS to make this tool more affordable than ever before.

Pairing HY-12 with WMS allows the user to bring in maps and images to assist you in laying out the storm sewer network and assigns data to your network that becomes a tedious task to do otherwise. Finally, the results are more interesting, clear, and useful when viewed in WMS than in the HY-12 report file.

WMS is available by download from the Aquaveo website: http://www.aquaveo.com

The HY-12 Storm Water Drainage System Model is the latest software package developed by Aquaveo for the Federal Highway Administration. It is a 1D hydraulic and rational method hydrologic model based on the principles in FHWA’s Hydraulic Engineering Circular No. 22 publication. HY-12 allows users to connect various elements to model a storm water drainage system.

HY-12 includes the following storm water elements:

  • · Rational Method Basin
  • · Channel
  • · Curb and Gutter
  • · Pipe
  • · Pipe Storage
  • · Access Hole
  • · Gutter Inlet
  • · Minor Loss
  • · Outfall
  • · Reservoir

This presentation will cover the updated and simplified interface to the HY-12 model in Aquaveo’s Watershed Modeling System (WMS).
