| Zusammenfassung |
| Water supply of most lowland cultures heavily depends on rain and melt water
from the upstream mountains. Especially melt-water release of alpine
mountain ranges is usually attributed a pivotal role for the water supply of
large downstream regions. Water scarcity is assumed as consequence of
glacier shrinkage and possible disappearance due to global climate change (GCC),
in particular for large parts of Central and Southeast Asia. In this paper,
the application and validation of a coupled modeling approach with regional
climate model (RCM) outputs and a process-oriented glacier and hydrological model
is presented for the central Himalayan Lhasa River basin despite scarce data
availability. Current and possible future contributions of ice melt to
runoff along the river network are spatially explicitly shown. Its role
among the other water balance components is presented. Although glaciers
have retreated and will continue to retreat according to the chosen climate
scenarios, water availability is and will be primarily determined by monsoon
precipitation and snowmelt. Ice melt from glaciers is and will be a minor
runoff component in summer monsoon-dominated Himalayan river basins. |
