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).

Storm Drain Menu

The Storm Drain menu is available in the map module when a Storm Drain coverage type is selected as the active coverage. This menu contains the Map→1D Schematic menu command. The menu is shown below:

Map to 1D Schematic

The Map→1D Schematic menu item creates a hydraulic schematic based on the configuration of the arcs and nodes in a Storm Drain or 1D Hydraulic Centerline coverage. If a schematic already exists for this coverage, the existing schematic is updated based on the coverage configuration.
