During the filling of the STP with data, emphasis had been laid on a single scenario only - scenario 1. However, the later balancing and allocation showed, that demands for this scenario can not be fulfilled in a sustainable way. While the balancing and allocation module permits simply to reduce agricultural demands in critical areas, no reduction of municipal demands is offered. Furthermore, a reduced municipal demand would cause less wastewater and consequently less inflow to reservoirs.
Therefore, a tool has been demanded for the quick generation and modification of data for alternative scenarios 2 and 3. It should take advantage of the log files, which are keeping all relevant entries. Than, the principal entries should be modified, and, the STP recalculated again.
It has to be remembered, that only data from the same scenario can be combined for balancing. Therefore, data have to be for new scenarios even if the data do not differ from the already existing scenario 1. This is no "waste" of hard disk space, as the modules fill all years and all scenarios, if data are not calculated just a zero has been stored.
Another advantage of the quick scenario builders is, that these forms provide a countrywide overview of the total demand /resources, as all spatial selections are shown simultaneously. Note: if there are duplications in the spatial selections, demands resp. resources would also be shown double, as the same STP-entry is read twice.
Quick Scenario builders are now available for all preprocessing modules (except for the rainfall-runoff module).
The following principal parameters can be changed:
Note: The Reservoir Safe Yield module (which is part of the balancing package) still needs to be run manually, as it can only process one scenario at a time.
Within the Preprocessing module, each quick scenario builder is available through selecting the option (radio) button and then pressing, the magic wand command button .
