Integrated System Analysis to Understand the Implications of the Asian Monsoon System on the Tibetan Hydrology with Focus on Nam Co Basin (Tuebingen Group)
In frames of DFG Priority Programme (Schwerpunktprogramm) 1372
Tibetan Plateau: Formation - Climate - Ecosystems (TiP)
Goals
The objective of the project is better understanding of the driving forces controlling hydrological processes in the context of a changing climate and monsoon dynamic on the Tibetan Plateau and the identification of hydrological feedbacks to changing climate conditions by analysing and modelling its underlying spatially and temporally variable hydrological components and processes. This is achieved by the distributed hydrological modelling parametrized by remote sensing data. The modelling part is carried out by the Jena Group (http://www.geoinf.uni-jena.de/7026.0.html) while the Tuebingen group is in charge of the derivation of information from remote sensing data.
In the 1st and 2nd project phase the focus was on Nam Co Basin which is a representative example of a large endorheic system on the Tibetan Plateau. In the 3rd phase the attention should be extended to endorheic lake basins following two transects across the Tibetan Plateau in order to understand regional variations in reaction of hydrological system to the changing climate conditions and to extend the understanding of the hydrological processes to the whole Tibetan Plateau.
