A hydrograph can be computed from any of the supported hydrologic models. A hydrograph can also be defined/imported using the New command in the Hydrograph menu. This option allows you to copy a hydrograph from the clipboard, or open a text file using the text import wizard and define it for a selected basin or outlet node.
The hydrograph should be selected prior to bringing up the detention basin calculator.
New Hydrographs
Sometimes it is useful to create a new hydrograph, not computed by one of the WMS models, for calibration or further analysis. This can be done using the New command in the Hydrograph menu after selecting the basin/outlet where you wish to associate the new hydrograph. When selecting this command you can choose to import an existing text file or paste from the Windows clipboard a hydrograph that has previously been cut/copied from a spreadsheet or text file. In either case the data will be processed using the Text Import Wizard and a new hydrograph created for the selected basin/outlet.
The text file or copied data should include a column for time and a column for flow. A couple of limitations associated with creating a new hydrograph in this fashion are that the times must be in minutes and the time step must be constant. After copying from the clipboard, or opening the text file the data will be placed in the Text Import Wizard and you will be able to identify header rows, set the starting row, and map the columns to their respective data fields.
