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 having created a 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 having done this, a user can define model-specific data on the hydraulic schematic in the river module.

In other words, here are the steps to 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 model-specific data in the river module (currently, only SWMM model data is supported).

Storm Drain Menu

Select Model dialog as brought up by the Map → 1D Schematic command

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.

FHWA Storm Drain Simulations

NOTE: The FHWA Storm Drain coverage and model has been deprecated in versions of WMS after 9.1. You can still use this model, but it will be taken out and replaced by the HY-12 storm drain model in future versions.

Run Simulation

A user can build an FHWA Storm Drain simulation by creating Storm Drain-FHWA type coverage. The Storm Drain coverage type (NOT Storm Drain-FHWA) is used for building HY-12 and SWMM models.

When running an FHWA Storm Drain simulation (by invoking the Run Simulation of the Storm Drain-FHWA menu), an input file is saved and the storm drain program started using the defined input file. An output file name is also required and all of the output generated by the hydraulic analysis is saved to this file.

Plots of results can be created by reading the output file generated using the Read Solution command and then setting up an FHWA Storm Drain plot using the Plot Wizard.

Read Solution

If you run the FHWA storm drain model and have a solution file, plots of results can be created by reading the output file using the Read Solution command and then setting up an FHWA Storm Drain plot using the Plot Wizard.

Save Simulation

If you have defined arcs representing pipes and nodes in a Storm Drain-FHWA coverage, you can save the simulation using the Save Simulation command. WMS will save a Storm Drain model in the correct format to run the FHWA storm drain model.

Storm Drain Feature Objects

The Storm Drain Coverage used to generate HY-12 and SWMM models does not have any attributes for feature objects. This coverage is for storing the storm drain geometry. The FHWA Storm Drain Coverage allows attributes for Storm Drain nodes.
