WMS:Storm Drain

The storm drain coverage is used for defining urban hydraulic models. The procedure for defining hydraulic models in this coverage is similar to defining other hydraulic models since streams, ditches, and sewer pipes are created from upstream to downstream. Currently, this coverage only supports links and nodes for the SWMM model.

When you have created your conceptual model in the storm drain coverage, select the Map→1D Schematic menu item from the Storm Drain menu to generate a hydraulic schematic from the coverage. After you have done this, you can define your model-specific data on the hydraulic schematic in the river module.

In other words, here are the steps you would take to define a simple urban hydraulic model:

1. Create a new storm drain coverage.

2. Define any pipes, ditches, and streams as arcs going from upstream to downstream in the storm drain coverage.

3. Select the Map to 1D Schematic menu item

4. Go to the River Module

5. Define your model-specific data in the river module (currently, only SWMM model data is supported).
