English Name: Deciphering changes of river discharge on Tibetan Plateau
Keywords: climate change; vegetation dynamics; landscape co-evolution; runoff
generation; attribution of runoff changes
Improved understanding of hydrological response to co-evolution of climate and land surface properties is the key research thrust among the hydrology community. Tibetan Plateau provides a unique avenue to investigate the changing hydrological regimes under this context that can greatly advance our knowledge on hydrological cycles in alpine regions. The knowledge will subsequently provide foundations for sustainable water resources and flood risk management as well as maintaining harmonious diplomatic relations between China and its neighbors. The proposal aims to solve one of the three key questions raised in the Major Research plan funded by NSFC, and particularly focuses on the mechanisms of changes in runoff with diverse contributing sources. The following achievements are expected: (1) the co-evolution mechanisms of the integrated soil-ice-snow-vegetation system under the context of climate change over Tibetan Plateau; (2) the physical mechanisms of hydrological response to key land surface properties; (3) the characterization of historical and future changes in runoff and flood risk over Tibetan Plateau. These achievements will collectively contribute to innovative theories and tools for hydrology research in alpine regions that can be further applied into practical challenges involved with water security and collaborations across the borders.
