Modelling hydrological responses to climate change in a data-scarce semiarid basin in the Tianshan Mountains
The Tianshan Mountains, known as the Water tower of Central Asia, are an essential freshwater source for downstream rivers, residents, irrigation agriculture and ecosystems in Central Asia. Climate in this semiarid region has changed from warm-dry to warm-wet in the last decades. Water resources are highly sensitive to climate change, and their availability is expected to become more unstable in the future. However, hydrological processes in glacierized basins are poorly known due to data scarcity and complex snow and glacier melt dynamics. It is therefore particularly important to improve our understanding of climate change and its impacts on hydrological regimes in dry, glacierized mountain regions such as the Tianshan Mountains. Emphasizing the research gaps related to the scarcity of observational data and lack of understanding of climate variability and hydrological regimes, the aim of this thesis is to model hydrological responses to climate change in a data-scarce glacierized basin in the Tianshan Mountains to better understand mountain hydrology. Spatio-temporal changes of climate change, climate extremes, hydrological and cryosphere were summarized based on data analysis and literature review. ...
