Most of the world’s mountains are wealthy in water and, as such, play a pivotal function within the worldwide water cycle. they supply water for various human makes use of and ecosystems. becoming water calls for in addition to weather swap will bring about ever-increasing strain on mountain waters. Overcoming water-use conflicts and keeping the ecological functioning of mountain waters provides a hugely not easy job and is imperative for sustainable development.
This booklet generally portrays the hugely assorted attributes of mountain waters and demonstrates their paramount significance for ecological and societal improvement. The broad summaries at the medical fundamentals of mountain waters are supplemented with concerns at the diversified water makes use of, wishes for administration activities, and demanding situations concerning sustainable water administration. This assessment matters not just the mountain parts themselves but in addition downriver reaches and their surrounding lowlands, and, as a result, the connection among mountain and lowland water issues.

Extra resources for Alpine Waters

Example text

However, snow cover or groundwater storage levels as well as lake levels can also be subject to fluctuations that extend over several months (cf. Fig. 22). Glaciers as well as large groundwater reserves located deep underground are capable of storing water for years or even decades. Glacial fluctuations are discussed in Table 1 of “Impact of Climate Change on Water Resources” [88]. The effects of storage are reflected in the runoff regime (cf. Sect. 2). These storage depots help to offset shortages during dry periods.

Furthermore, the precipitation gradient for the south side of the Alps is smaller compared to the northern side of the Alps, although overall it exhibits higher levels of precipitation. The differences in precipitation characteristics to be observed on the north and south side of the Swiss Alps are largely a result of the different proportions of advective and convective precipitation events, as well as the differing intensity of precipitation. However, as mentioned above, topographical characteristics can also exert a significant influence [32].

19). As a general principle, there is a close correlation between the regime type (Sect. 2) and the seasonal occurrence of low water periods. In the alpine catchments the lowest flow rates usually occur in the winter half-year, when precipitation is stored in the form of snow. On the north side of the Alps, the absence of low water during dry periods in summer is primarily attributable to snow and icemelt in the spring [65]. 42 B. Wehren et al. g. the Valais or the Tyrol – drought in summer can also produce low waters.
