Hydrographs are created within scenarios. Therefore, they are either created individually for each scenario or are transferred from another scenario. To create and edit hydrographs, follow Menu bar → System → Yearly pattern / Weekly pattern / Daily pattern. After creation, the hydrographs are then stored in the database.

The menu item View updates the hydrographs, or sorts them alphabetically. Using the menu item Time series pattern, new hydrographs are created, edited, or deleted. This is also possible via the function bar Datei:Ganglinie003.png.

Creating Annual Patterns

To create a new hydrograph, click on the icon Datei:Ganglinie013.png. This opens a window with the following question: Would you like to create a flexible annual pattern?

Confirmation with Ja:

a flexible period can be created for the hydrograph. The following window opens:

In the panel Name, the name of the chart is defined. Then, there are two options for the creation of a time series.

  1. Individual Creation of a Hydrograph
    Double-click the first line to edit the displayed date and value. Afterward, double-clicking the second line selects it for edits. Clicking the Edit button allows entering flexible times with their corresponding values. Confirming the values with OK inserts the values in the chart, and the next line is selected automatically for editing. Times can be particularized in the desired resolution. Clicking the Cancel button, all previously edited entries are saved and the editing mode is terminated.

    Lines can be removed by clicking the button Delete. The mean value is calculated automatically from the entered values. If the interpolation mode is active, the values are interpolated between two dates. If the interpolation mode is not active, the value for a date is assumed constant until the next certain date.
    The following figure shows an exemplary result for an annual pattern:

  2. Transferring Data from Existing Hydrographs
    If yearly, weekly, or daily hydrographs already exist in other scenarios, they can be transferred by clicking on the symbol Datei:Ganglinie014.png. An overview of all projects and scenarios opens. Now, click on the corresponding scenario and select the corresponding hydrograph. By clicking the Apply button, the data is transferred.

Confirmation with Nein:

a constant hydrograph is created and for each month, a value must be specified. Again, the hydrograph can be created individually or transferred from another scenario. You can choose between active and inactive interpolation mode. The input of the values is conducted by clicking on the corresponding line and entering values.

After the flexible or constant annual pattern and the corresponding hydrograph have been created, the graph is saved with the Save button. By clicking the Cancel button, no saving takes place.


Creating Weekly Patterns

When creating hydrographs for daily patterns, a window opens directly containing a date for each day. Same as with annual patterns, you can edit the pattern yourself or take it over from another scenario (see annual pattern). You can also choose between active and inactive interpolation mode. The values are entered by clicking on the corresponding line. After the weekly graph has been created, the graph is saved with the Save button. With the Cancel button no saving takes place.

Creating Daily Patterns

When creating hydrographs for daily patterns, a window opens directly containing a date for each hour. Here, too, you can create the hydrograph yourself or take it from another variant (see Hydrograph). You also have the choice between interpolated and non-interpolated values. The values are entered by clicking on the corresponding line. After the daily graph has been created, the graph is saved with Save. With Cancel no saving takes place.
