A major proportion of discharge in the Juntanghu river basin is contributed by its glacier-fed river and snow catchments situated in northern mid-slope of Tianshan Mountain, Northwest China. The Mann-Kendall trend test based on the 50 years data (1961 to 2011) were used for analysis of the climate change trends and the application of the SWAT model under different climate change scenarios show that watershed hydrological cycle would alter under different climatic scenarios. This suggests that the reservoirs will be necessary for large flow storage to meet the need of the flood control, water supply, etc.

Abstract


A major proportion of discharge in the Juntanghu river basin is contributed by its glacier-fed river and snow catchments situated in northern mid-slope of Tianshan Mountain, Northwest China. The Mann-Kendall trend test based on the 50 years data (1961 to 2011) were used for analysis of the climate change trends and the application of the SWAT model under different climate change scenarios show that watershed hydrological cycle would alter under different climatic scenarios. This suggests that the reservoirs will be necessary for large flow storage to meet the need of the flood control, water supply, etc.
