| Zusammenfassung |
| Alpine regions are particularly affected by seasonal variations in water
demand and water availability. Especially the winter period is critical from
an operational point of view, as being characterised by high water demands
due to tourism and low water availability due to the temporal storage of
precipitation as snow and ice. The clear definition of summer and winter
periods is thus an essential prerequisite for water resource management in
alpine regions. This paper presents a GIS-based multi criteria method to
determine the winter season. A snow cover duration dataset serves as basis
for this analysis. Different water demand stakeholders, the alpine hydrology
and the present day water supply infrastructure are taken into account.
Technical snow-making and (winter) tourism were identified as the two major
seasonal water demand stakeholders in the study area, which is the
Kitzbueheler region in the Austrian Alps. Based upon different geographical
datasets winter was defined as the period from December to March, and summer
as the period from April to November. By determining potential regional
water balance deficits or surpluses in the present day situation and in
future, important management decisions such as water storage and allocation
can be made and transposed to the local level. |
