GenCade has the capability to model the structures listed below. The GenCade menu includes commands to view a table of the structures of a specific type included in a simulation. Some structures can also be selected interactively if they have a geographic attribute such as length.

Breakwaters

GenCade Detached Breakwaters table

Parameters for characterizing breakwaters include start and end location, depth, and transmission coefficient. To define a breakwater, proceed with the following steps:

  1. Select the Create Breakwater Create Breakwater Tool.svg tool and click with the left mouse button to specify the start and end location.
  2. Select the menu option GenCade | Edit Breakwaters. The GenCade Detached Breakwaters dialog will appear allowing the entry of breakwater parameters. At this point, verify that the parameters are correct. Further information concerning the selection of breakwater parameters is provided in the GenCade model documentation.

Seawalls

Parameters for characterizing seawalls include start and end location. To define a seawall, proceed with the following steps:

  1. Select the Create Seawall Create Seawall Tool.svg tool and click with the left mouse button to specify the start and end location.
  2. Select the menu option GenCade | Edit Seawalls. The GenCade Seawalls dialog will appear allowing the entry of seawall parameters. At this point, verify that the parameters are correct.

Groins

GenCade Groins table

Parameters for characterizing groins include length, permeability, diffraction, and depth. To define a groin or jetty, proceed with the following steps:

  1. Select the Create Jetty/Groin Create Groin Tool.svg tool and click to specify the jetty or groin location. The groin or jetty will be created perpendicular to the grid.
  2. Select the menu option GenCade | Edit Groins. The GenCade Groins dialog will appear allowing the entry of groin and jetty parameters. At this point, verify that the parameters are correct. Further information concerning the selection of groin and jetty parameters is provided in the GenCade model documentation.

Parameters that can be edited for groins include:

  • Cell Index
  • Length
  • Permeability
  • Diffracting
  • Seaward Depth

Inlets

To create an inlet, create a feature arc, right-click on it, select Attributes and change the attribute to Inlet. Inlets have a name, a left and right bypass coefficient, cell positions, shoal volumes, jetties, and dredging options.

GenCade Inlets (Reservoir Model and Jetties) table

Cell Positions

Cell beginning and ending positions can specified for the inlet and its left and right bypass. These can be set by creating attachment arcs by the inlet before mapping to a 1D grid. If there are two inlets with one attachment arc in between, the attachment arc will be associated to the inlet closest to the arc.

GenCade Inlet Position dialog

Shoal Volumes

The initial and equilibrium shoal volumes can be specified for the ebb, flood, bypass (left and right) and attachment (left and right) shoals.

GenCade Inlet Shoal Volume dialog

Jetties

The jetties to the left and right of the inlet can be given a length, permeability, and a seaward depth. Also, whether the jetty exists and is diffracting can also be specified.

GenCade Inlet Jetties dialog

Dredging Events

Dredging events can have a beginning and ending date, which shoal is to be mined, and the amount to be removed from the specified shoal between the beginning and ending date.
