Long Term Quantification of Climate and Land Cover Change Impacts on Streamflow in an Alpine River Catchment, Northwestern China

Abstract: Abstract:Quantifying the long term impacts of climate and land cover change on streamflow is of great important for sustainable water resources management in inland river basins. The Soil and Water Assessment Tool (SWAT) model was employed to simulate the streamflow in the upper reaches of Heihe River Basin, northwestern China, over the last half century. The Sequential Uncertainty Fitting algorithm (SUFI-2) was selected to calibrate and validate the SWAT model. The results showed that both Nash-Sutcliffe effi… Show more

“…The climate is characterized by cold and dry conditions in winter and warm and humid conditions in summer with large spatial and temporal heterogeneity. The multi-year average air temperature ranges from −5 to 4 • C. The air temperature increased by 0.37 • C/10yr in 1980-2010, which is faster than the rate over the last 60 years by 0.30 • C/10yr [29]. The multi-year average annual precipitation exceeds 400 mm, increasing by 15.5-16.4 mm for every 100 m rise in altitude.…”

“…The magnitudes of the estimated changes in the trend of temperature and precipitation were estimated by using a simple non-parametric procedure that Sen developed. The Sen [30] method alleviates the consequences of anomalous trends by using the median of the series of slopes as the judgmental foundation [13]. The Q i is given by the following:…”

“…From the hydrological models available, we chose the Soil and Water Assessment Tool (SWAT) model due to the fact that this model has been used worldwide to simulate the hydrological cycle and has been used extensively to evaluate the impacts of LULC changes on watershed hydrology [11]. Likewise, a multitude of studies have addressed separating the influences of human activities and climate variability on water resources using the SWAT model [3,[11][12][13]. However, only two references have been found on the application of the SWAT model to assess the impacts of LULC changes in Spain.…”

“…As a result, it is a widely used tool for the study of the hydrological effects of environmental change [18][19][20]. Yin [21] applied the SWAT model to quantify the impact of climate variability/land use change on the streamflow over a long historical time period. Kim [22] used SWAT model to evaluate the separated and combined impacts of future changes and land use changes on the streamflow.…”
