Define Water Quality Boundary Data

The Boundary Condition Set Editor provides two options for entering the required input data for all boundary locations within a boundary condition set. The first option allows input by boundary location, using the view by Location configuration. The second option enables data entry by constituent, using the view by WQ Constituent configuration. Both options open the editable data panel for data entry. To add input data by location for all required constituents:

1. From the Boundary Condition Set Editor, select the desired boundary condition set from the navigation bar (e.g., BoundaryConditionSet1).
2. Choose the desired editor configuration by selecting either the Location or WQ Constituent radio button (Boundary Condition Set Editor – Location Configuration – Enter Data Source).
3. Select the specific location and constituent of interest, which will open the editable data panel.

For example, if Austin Ck Conf is selected as the location and Dissolved Oxygen as the constituent, the corresponding editable data panel will open for input.

From the editable data panel, specify the constituent measured at the selected location. Once the data is entered, a plot window appears at the bottom of the panel, displaying the entered data.

The plot window provides two viewing options for the entered data:

• Plot Selected Data Source: This option displays a plot of the data entered for the currently selected data source.
• Plot All Defined Data Sources: Alternatively, selecting this option shows a group plot containing all the data entered from multiple data source options (Boundary Condition Set Editor – Location Configuration – Plot All Defined Sources ).

For example, if data is entered using both the Constant Value and DSS data source options, two separate plots will be displayed in the plot window.

Note: The x-axis of the plot window adjusts depending on the data source and whether the Boundary Condition Set Editor is opened from the Water Quality module or Simulation module (refer to Chapter 14). For instance, if the plot contains DSS data, the plot window will show the period of record (POR) for the selected HEC-DSS record when accessed from the Water Quality module. However, when opened from the Simulation module, the plot window will use the simulation time window.

The following sections provide instructions for entering boundary condition data from each data source option, along with specific details for each simulated constituent.
