Summary

Water resources play an important role in social and economic developments of nations. Because of climate change and the intensification of human activities, the floods and droughts occur more frequently. There has been considerable research addressing the influences of climate change and human activities on water resources in Yangtze River Basin, China. However, most previous researches focused on trend analysis of single hydrological component, and modelling of the hydrological components responding to climate change and human activities, not the relationships between water cycle components and climatic and land surface parameters. What’s more, some hydrological components haven’t been studied yet in Yangtze River Basin such as terrestrial water storage.

This project will focus on getting a better understanding of the response of water cycle components to climate change and human activities (Dam construction, Land-cover change) by studying the interrelationships between hydrological components and climatic, land surface parameters. Natural and anthropogenic contributions and the dominant contributor to the river runoff change will be detected. Furthermore, remote sensing technology will be employed to estimate some key variables of land surface hydrological processes, including terrestrial water storage, water level of Poyang Lake, the largest freshwater lake in the basin.

All this knowledge will lead to a better understanding of the hydrological response of Yangtze River Basin to climate change and human activities, which will be helpful for hazards control and water management of the large rivers.
