Introduction
QWAST allocates water based on priorities between users according to LHM. As the priorities in LHM 4.3 have been changed, QWAST also have changed to accomodate them. Before LHM 4.3, QWAST was reading district water demands based on user (e.g. water demand for irrigation). QWAST itself gave a priority to the user, which is as close as possible to LHM.
After LHM 4.3, QWAST is reading district demands per priority, he does not read the user (e.g. water demand priority 4). As a consequence, QWAST does not know any more who the user is. However, QWAST has now exactly the same priorities as LHM.
Switching between calculation modes
QWAST is backward compatible with version before LHM 4.3. The two ways of calculation is adjusted in the global.properties file:
- PRIO_TYPE_QST=Prioriteit (LHM 4.3)
- PRIO_TYPE_QST= (LHM before 4.3)
Note that in the display both options are available. The user should choose the corresponding display.
One more note: for the LHM 4.3 version some of the displays and scenarios are not (yet) supported.
Changes in modifiers and viewers
The district demands are no longer user demands, they only have priority. This is reflected in the data viewer:
The modifiers are also no longer valid for users but to priorities:
The viewers and modifiers for users are still present for compatbility. The user should be aware which caclulation mode he is using (prioriteit or not, ie. LHM 4.3 or before), and should use the corresponding modifiers and viewers. The not corresponding modifieres are not used, the not corresponding viewers show irrelevant data.
