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 .
Creating Annual Patterns
If confirmed with yes:
- a variable period can be created for the hydrograph. The following window opens:
Under Description the name of the chart is defined. There are now two possibilities to create a time series.
- Independent creation of a hydrograph
Double-click on the first line to edit the date and value. Double-click afterwards on the second line variable times with appropriate values can be entered in the mode edit values. With OK both entries are taken over and jump directly to the next line. The time specification can be refined as desired. With Cancel all entries are stored and the editing mode edit values is terminated.
With Edit another line can be added and removed with Delete. The mean value is calculated automatically from the entered values. With interpolation activated, the values are interpolated between two dates. If the field interpolation is not active, the value for a date is assumed constant until the next date.
Thus, the following annual cycle results:
- Take over of an already existing hydrograph
If yearly, weekly, daily hydrographs already exist in other variants, which can be taken over, click on the symbol . An overview with all projects and variants opens. Now click on the corresponding variant and select the hydrograph you are looking for. With Apply the data are transferred into their new time series.
If confirmed with no:
- a constant hydrograph is created, where a value is specified for each month. Again, the hydrograph can be created by yourself or taken from another variant. Likewise you have the choice between interpolated and not interpolated values. The input of the values takes place by clicking on the appropriate line.
After the variable or constant annual graph has been created, the graph is saved with Save. With Cancel no saving takes place.
Create weekly cycle
When creating weekly hydrographs, a window opens directly with a constant date for each day. Here, too, you can create the hydrograph yourself or take it over from another variant (see Yearly hydrograph). You also have the choice between interpolated and non-interpolated values. The values are entered by clicking on the corresponding line. After the weekly graph has been created, the graph is saved with Save. With Cancel no saving takes place.
Create daily cycle
When creating daily hydrographs, a window opens directly with the constant 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.
