Information - CR9 Mountain hydrology and climatology: present state and future scenarios (co-listed in HS)
The hydrological importance of mountains has several aspects. Orographic effects produce a higher precipitation input as compared to lowland areas. Snow cover, permafrost and glaciers act as seasonal and long-term storages. Runoff formed in high alpine catchments is not only beneficial to mountain regions themselves, but also to the surrounding lowlands. Therefore, mountain areas can be regarded as water towers that yield and preserve water and distribute it unevenly over time and space. Understanding the coupling of climate and hydrology and their pronounced variability is of great scientific and practical interest, especially against the background of global change.
This session addresses studies related to present-day interactions between climate and water as well as to their possible future scenarios. Contributions dealing with monitoring, modelling or remote sensing of any component of the water balance in mountain regions are welcome, independent of scale or geographic region. Of special interest are contributions from mountains in arid and semi-arid regions in addition to the well-investigated humid regions. Studies on the potential impacts of a warming climate on water availability in snow-dominated mountain regions and their forelands are at the central focus.
