The purpose of the 1D Module is to provide tools to perform one dimensional hydraulic modeling within SMS. The module include tools to process digital terrain (scattered datasets) and map data (coverages) to build the basic geometry necessary for a 1D hydraulic model.  Much of the information for developing [[SMS:SMS Models|models]] with these tools is described in the information on River coverages in the Map module.

The ''1D River Hydraulic'' tools are used to create, edit and apply networks of river reaches and cross sections. The created networks must be associated with a specific 1D model (currently the only major model supported is [[SMS:HEC-RAS|HEC-RAS]]. The module includes tools for visualizing results computed for cross sections and reaches.
Currently the only major model supported is [[SMS:HEC-RAS|HEC-RAS]].


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

Alternatively, It is possible to establish the hydraulic model without extracting cross section information from a TIN.  Cross sections which have already been surveyed can be assigning 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.

River networks are displayed as a schematic of reaches and cross sections. Networks may be georeferenced or purely symbolic. Each cross section is represented by a cross section icon displayed at the location of the cross section if the section is georeferenced, and reach icons, which are displayed on top of the first cross section in each reach. The icons can be moved according by selecting the icon and dragging it to the desired location.
 
The cross section attributes can be changed by using the '''Select Cross Section''' tool. Double-clicking on the desired cross section opens the ''River Cross Section Atts'' dialog which can be edited similar to the Map Module. The only difference is that the reach the cross section is attached to cannot be changed. Likewise the reach attributes can also be changed within the 1D River Hydraulic module.

The purpose of the 1D Module is to provide tools to perform one dimensional hydraulic modeling within SMS. The module include tools to process digital terrain (scattered datasets) and map data (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 1D Hyd Centerline and 1D Hyd Cross Section coverages in the Map module.

Currently the only major model supported is HEC-RAS.

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

  1. Import bathymetry data.
  2. Developing a 1D-Hydraulic Centerline coverage including the centerline and optional bank arcs.
  3. Creating the cross section arcs at important/required locations along the section of river being modeled.
  4. A shapefile can be used to map roughness values to line properties on the cross sections.
  5. Extracting cross sections from the TIN and establish the 1D Model.
  6. Export the GIS data and finish defining HEC-RAS (or other models).

Alternatively, It is possible to establish the hydraulic model without extracting cross section information from a TIN. Cross sections which have already been surveyed can be assigning to an arc. This, along with geo-referencing the data is done using the cross section editor in the 1D Hyd Cross Section coverage.

Module Menus

The 1D Module does not contain any unique menus specific to the module that are not model menus. The '"HEC-RAS menu for HEC-RAS 1D can be found in this module.

See HEC-RAS for more information.
