“…The result of annual runoff in the Beiluo River had a significant downtrend during the study period, which is consistent with previous studies [16,46,47]. Another reason for this is the regulation of 42 reservoirs [16,23,46].…”

Climate change and human activities influence runoff and sediment load in an integrated way. However, under similar climate conditions the variability in runoff and sediment load is mainly a result of human activities. In this study, the change trends of runoff and sediment load were detected with linear regression analysis for the Beiluo River on the Loess Plateau, China. The impact of human activities on runoff and sediment was examined under similar weather conditions based on continuous monthly data of climate and runoff and sediment load from 1958 to 2012 at the Zhuangtou Hydrological Station. The results showed that: 1) Annual runoff and sediment load varied greatly and declined significantly in the study period, but precipitation and potential evapotranspiration (ET 0 ) estimated by the Food and Agriculture Organization (FAO) Penman-Monteith Method had no significant trend. 2) The paired periods with similar precipitation and ET 0 were selected if they had similar annual amounts (less than 2%) and similar changing process controlled by monthly data (P<0.05). It has been demonstrated that the decreases of runoff and sediment load were mostly (60%, 70%, 75%) induced by human activities within the paired periods.

Abstract. Water resources in river systems have been changing under the impact of both climate variability and human activities. Assessing the respective impact on decadal streamflow variation is important for water resource management. By using an elasticity-based method and calibrated TOP-MODEL and VIC hydrological models, we quantitatively isolated the relative contributions that human activities and climate variability made to decadal streamflow changes in the Jinghe basin, located in the northwest of China. This is an important watershed of the Shaanxi province that supplies drinking water for a population of over 6 million people. The results showed that the maximum value of the moisture index (E 0 /P ) was 1.91 and appeared in 1991-2000, and the decreased speed of streamflow was higher since 1990 compared with . The average annual streamflow from 1990 to 2010 was reduced by 26.96 % compared with the multiyear average value (from 1960 to 2010). The estimates of the impacts of climate variability and human activities on streamflow decreases from the hydrological models were similar to those from the elasticity-based method. The maximum contribution value of human activities was 99 % when averaged over the three methods, and appeared in [1981][1982][1983][1984][1985][1986][1987][1988][1989][1990] due to the effects of soil and water conservation measures and irrigation water withdrawal. Climate variability made the greatest contribution to streamflow reduction in 1991-2000, the values of which was 40.4 %. We emphasized various source of errors and uncertainties that may occur in the hydrological model (parameter and structural uncertainty) and elasticity-based method (model parameter) in climate change impact studies.

“…The YRCC measured water consumption for irrigation, flood protection, and water stored in reservoirs, and also water diversion from the river to basin [31]. However, water volumes abstracted for industrial and domestic consumption are not measured by the YRCC [31]. Soil conservation measures mainly considered are practices with a form of level terrace, afforestation, grassland, and check dam.…”
