The WQ on Reach Elements category allows you to choose whether to model salinity on the member elements.

This is the default, no-action method for this category. No slots are instantiated by this method. When this method is selected, all of the member elements are configured to not model salt. That is, the None method is selected on each reach. See “None” for details.

When this method is selected, all of the member elements are configured to model salt. That is, the Salinity method is selected on each reach; see “Salinity” for details. Also, concentration links are created between the aggregate and the first and last element and between successive reach elements. For example Element1.Salt Concentration Outflow is linked to element2.Salt Concentration Inflow. These links are made automatically.

When this method is selected, all of the member elements are configured to model salt. That is, the Mass Balance Salinity method is selected on each reach; see “Mass Balance Salinity” for details. Also, concentration links are created between the aggregate and the first and last element and between successive reach elements. For example Element1.Salt Concentration Outflow is linked to element2.Salt Concentration Inflow. These links are made automatically.

Following is the available dispatch method when the solution approach is Well Mixed Salt or Discretized Salt.

This method computes the total inflow and outflow salt mass only. The salt concentrations should come from the linked element objects or from upstream/downstream objects (or via input or rules).

This method does the following:
