This is the appearance of the Inflow/Outflow tab of the Reservoir Coefficients dialog:
Following is a description of the parameters associated with Inflow / Outflow. Refer to the main Reservoir Coefficients page for information on other categories of coefficients. To save the changes made when closing this dialog, click OK. To ignore changes, click Cancel.
With the single segment model selected, the outlets spreadsheet contains information about the spillway and controlled outlets of the lake or reservoir. The type of connection between segments is shown for any upstream segment when multiple segment simulation is selected. The first row must contain information about the spillway. Controlled outlets such as turbine release, gated spill or diversions can be added to the spreadsheet by clicking on the Add button to select a managed flow (.FLO) file and then filling in the spreadsheet entries. Click on Remove to delete the selected outlet. The second column of the spreadsheet has the elevation of the outlet (m above MSL). The third column contains the width of the outlet (>0 m). The fourth column value gives four choices: release, diversion, submerged weir, and follow inflow. “Release” means that the outlet discharges to the river downstream of the dam and “Diversion” means that the outlet’s discharge is diverted away. The latter two types specify how flow is transferred from an upstream segment in a reservoir simulated with multiple segments. “Submerged Weir” represents a submerged weir between segments. Specify the elevation of the weir. For “Follow Inflow”, flow between segments follows the same pattern as inflow into the upstream segment. To change values, click with the left mouse button in a cell and change the value.
If there are diversions from elsewhere in the watershed which discharge to the reservoir, click on Add next to Diversions to Reservoir to select the managed flow file for the diversion. To remove a diversion, select it in the list and then click Remove.
Use Release Adjustment Method: if method is checked, instead of simulating reservoir elevation based on outflow, WARMF will use observed elevation data to calculate the release for each day to balance volume in the reservoir at the specified surface elevation. The adjustment made to the outflow is reported in constituent output as Flow Adjust (> 0 released less water, < 0 released more water). This applies to either single segment or multiple segment simulation.
When the Apply Changes To Selected button is checked, changes made to the coefficients of the reservoir segment being edited will be made to all selected reservoir segments. When the Apply Changes To All button is checked, changes made to the coefficients of the reservoir segment being edited will be made to all reservoir segments.
