Example of a hydraulic model

The primary purpose of the hydraulic modeling interface within WMS is to process digital terrain and map data (TINs and coverages) to build the basic geometry necessary for a 1D Hydraulic Model. Much of the information for developing models with these tools is described in the information on River Tools in the Map module.

The general process for developing a model consists of the following steps:

  1. Prepare a background digital terrain model that represents the river channel bathymetry and surrounding floodplain with enough detail to substantiate the modeling objectives.
  2. Develop a 1D-Hydraulic Centerline coverage including the centerline and bank arcs.
  3. Create the cross section arcs at important/required locations along the section of river being modeled.
  4. An Area Property coverage can be used to map roughness values to line properties on the cross sections
  5. Extract cross sections from the TIN and establish the 1D Model
  6. Export the GIS data and finish defining HEC-RAS (or other model).

It is possible to establish the hydraulic model with extracting cross section information from a TIN. Cross sections which have already been surveyed can be used by assigning them to an arc. This, along with geo-referencing the data is done using the cross section editor from the River Tools menu in the Map module (when River Tools is the active model).

Default Hydraulic Model

The commands in the Hydraulic menu are used in defining any of the supported hydraulic models supported by WMS. The default model is controlled using the drop-down combo box in the Edit Window. Whenever selecting a command for another model, the default model will be updated to specify that model.

Hydraulic Schematic

A hydraulic schematic is a schematic tree-based representation of a map-based conceptual model. It represents a single hydraulic model. It is displayed as a node under the Hydraulic schematic data in the project explorer and is the key data type in the river module.

Hydraulic Modeling Tools

The toolbar for the Hydraulic Modeling module.

The toolbar for the WMS Hydraulic Modeling module has a variety of tools useful for editing and selecting items within a topological tree. The tools are described below.

Select River Cross Section
The Select River Cross Section WMS SelectRiverCrossSectionTool.svg tool is used to select a cross section and edit the associated parameters from within the hydraulic modeling module. It is equivalent to editing the attributes of a cross section feature line from within a 1D Hydraulic Cross Section coverage in the map module.
Select River Reach
The Select River Reach WMS SelectRiverReachTool.svg tool is used to select a reach and edit the reach data from within the hydraulic modeling module. It is equivalent to editing the attributes of a centerline from a 1D Hydraulic Centerline coverage in the map module.
Select Hydraulic Node
The Select Hydraulic Node WMS SelectHydraulicNodeTool.svg tool is used to select a hydraulic node and edit the node data from within the hydraulic modeling module.
Select Hydraulic Link
The Select Hydraulic Link WMS HydraulicLinkTool.svg tool is used to select a hydraulic link and edit the link data from within the hydraulic modeling module.
