WMS:CE-QUAL-W2 Branches
This feature allows the user to edit the features of a branch. This is done by highlighting the desired branch in the Polygon Branch Attributes dialog. The Branch ID field is used to number branches. The Main stem checkbox should be checked if the branch is the main stem of the waterbody. Checking the Selective withdrawal checkbox activates the Structures button. Selecting this button opens a dialog for defining any selective withdrawal structures the user may wish to add. The 'Define precipitation, Define precipitation temperatures, and Define precipitation concentrations buttons open dialogs in which the user can add precipitation and its temperature and constituent concentrations to the CE-QUAL simulation. Each dialog also features an import function which allows the user to import either a W2 input file or a comma or space delimited text file. The Get lengths and orientations of branch segments tool allows the user to trace the flow path of the branch and returns the lengths and orientations of each segment in the branch.

The boundary conditions tab of the polygon branch attributes dialog is used to define the upstream and downstream boundary conditions. For the upstream boundary condition there are three options to select from: external head, external flow, and internal head.
When external head is selected the Define head elevations, Define head temperatures, and Define head concentrations buttons become active. Selecting these buttons opens dialogs that allow the user to specify the elevations, temperatures, and concentrations of the external head.
When external flow is selected the Define inflow flowrates, Define inflow temperatures, and Define inflow concentrations buttons become active. These buttons open dialogs that allow the user to specify any inflows and the temperature and constituent concentration of the inflow.
Selecting internal head specifies that the branch is attached to another branch. Nothing else is required when this option is selected.
The downstream boundary condition has three options to choose from: external head, external flow and internal head.
When external head is selected the Define head elevations, Define head temperatures, and Define head concentrations buttons become active. Selecting these buttons opens dialogs that allow the user to specify the elevations, temperatures, and concentrations of the external head.
When external flow is selected the Define outflow flowrates button becomes active. This button leads to a dialog that allows the user to specify any outflows from the branch.
Selecting internal head specifies that the branch is attached to another branch. Nothing else is required when this option is selected.

In the segment tab of the branch attributes dialog (shown below) the user can edit segment parameters of the branch and assign upstream and downstream segments. This is done by highlighting the desired segment and then selecting the appropriate segment parameter button.

The distributed tributary tab is used to add a distributed tributary to the branch. To do so the user must check the box which then activates the Define inflow flowrates, Define inflow temperatures, and Define inflow concentrations buttons. These buttons open dialogs where the user can create input files for the distributed tributary.
