Quick Scenario Builder - Losses Demands

This "Quick Scenario Builder" gives you a complete overview of total water demands due to losses in municipal distribution networks as well as a single user interface to quickly build scenarios 2 and 3 out of data previously entered under scenario 1.

No distinction is made between

When the form opens, it shows data for the first balancing year and the dry year type.

A different balancing year is selected by year-selector on top of the form ,

The data table in the form shows the spatial selection (the descriptive name entered in the log table) and the total annual demand as saved in the STP table STP_LOSSES as monthly volumes of each demand center.

The relative losses shown on the right side are not a data table but rather a list box permitting the selection of records for updating.

Data manipulation is possible in 2 different ways:

  1. Fill data: For scenario 2 or 3 selected by the fill-button located under the column, data from scenario one are copied. This fills the log-table data from scenario on to the selected scenario. Afterward, losses are recalculated from municipal, tourist and industrial demand data. Attention, this is a very demanding tasks and will take a long time! Finally, the display of demand volumes and relative losses is refreshed.
  2. Recalculate data: The 2nd option makes only sense after the scenario has already been populated with data. You have to select one or more records in the list box (showing the assumed losses of the distribution networks) and have to enter a multiplication factor, with which these relative losses are to be modified. Select the option if only the year currently shown should be updated (this is the default), the year shown and the following years or even all years. After records have been selected and the multiplication factor has been set to a value <1, the hammer-button becomes enabled and can be pressed . This will recalculated the relative losses and recalculate the resulting demands, but only for the selected spatial selection and year.
