| Zusammenfassung |
| The Himalayan glaciers are source of numerous large Asian river systems, including the
Indus, Ganges, and Brahmaputra, which provide water for 1.5 billion people. This region is
among areas that are the most sensitive to climate change. Shrinking of the glaciers is
expected to significantly affect hydrologic responses of glaciated basins. Retreat of glaciers in
these basins is predicted to cause severe water crisis in these basins. However, glacier
behaviours are not well represented in most current hydrological models. The objective of the
present study is to test performance of a coupled model consisting of a hydrological model
and a glacier retreat model. The hydrological model is a distributed HBV model, simulating
runoff response to water input into catchment. The glacier retreat model is a distributed
glacier-specific model, Δh-parameterization describing ice redistribution caused by glacier
movement. The Beas River basin in the Northern India is selected as focus area
because of its high representativeness of the Himalayan basins and availability of
data. This study will not only improve the HBV model for hydrological studies in
glaciated catchments, but also contribute to improved understanding and modelling of
glacier hydrology. The coupled model will be a useful tool for water resources
projections and hydropower planning in a far future on highly glaciated basins. |
