Following is the appearance of the Stage-Flow tab of the Reservoir Coefficients dialog:
Following is a description of the parameters associated with Stage-Flow. 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.
The spillway rating curve for the reservoir must be entered into the spreadsheet. To change values, click with the left mouse button in a cell and change the value. Enter water surface elevations (m above mean sea level) in the left column and the corresponding flow (>=0 m3 / s) in the right column. The graph automatically updates itself as data is entered in the spreadsheet. The flows for the two lowest stages should be zero for proper interpolation.
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.
