The Tibetan Plateau has an outstanding relevance for the global climate dynamics through its impact on the Asian monsoon system, which in turn causes feedbacks to the vulnerable Tibetan ecosystem. Considering global climate change, little knowledge is given on the impact of the monsoon dynamics on the eco-hydrological system, but evidence of melting glaciers and permafrost as well as increasing evapotranspiration rates indicate significant system changes regarding water availability.
The main objective of this research study is the development of an integrated system analysis approach in order to understand the hydrological implications of the Asian monsoon system on the Nam Co Basin, linking lake level fluctuations with water balance modelling of its tributaries. Integrated field studies, geostatistics, remote sensing and GIS techniques will provide the spatio-temporal data, parameter and information required for distributed, process-oriented hydrological modelling, utilizing the J2000 model. This will result in a prognostic assessment of the impact of climate change affected monsoon dynamics on the water balance of Tibetan basins. The received information and model results will be incorporated into ITIS, the Integrated Tibet Information System.
