Abstract null null The drought events during the summer monsoon season (June-September) have a considerable impact on the water availability and major staple crop production in India. In this study, the temporal and spatial variability of drought events has been examined utilizing the standardized precipitation index (SPI). Moreover, the future drought events pattern has been investigated based on four shared socio-economic pathways-based scenarios (i.e., SSP1-2.6, SSP2-4.5, SSP3-7.0, and SSP5-8...

Abstract null null Systematic model error is caused by the unreasonable simplification of real groundwater system, which damages the reliability of groundwater model prediction. Gaussian process regression (GPR) is a popular data-driven method used to build a statistical complementary model to correct systematic prediction error and improve model prediction. Kernel function is a crucial component of GPR, it represents the assumptions on systematic prediction error that we want to learn. In order...
Abstract null null The widely used Feddes reduction function (FRF) was reviewed in the context of its merits and shortcomings for modeling root water uptake (RWU), crop transpiration, and soil water balance components. The empirical nature of the FRF was contrasted to few calibrations reported in the literature, and the conditions where the correct operation of the FRF was of limited importance were discussed. Some alerts regarding the feasibility of this function in hydrological studies were pr...
Abstract null null As the largest tributary of the Yellow River, the Wei River drains a basin mainly comprising two different geological settings, i.e., the Chinese Loess Plateau (CLP) in the north covered by Quaternary loess and the Qinling Mountains area in the south. Exploring the influence of natural weathering processes and human activities on river chemistry has high significance in understanding chemical transport from the Wei River to the Yellow River. The geochemical characteristics of ...

Abstract null null The construction of cascade reservoirs upstream of the Three Gorges Reservoir (TGR) has been greatly intensified in the 21st century. While research attention is dedicated to the downstream effects of the TGR, few studies have been focused on the radical change of upstream inflows to the TGR. In this study, we reveal the impact of upstream cascade reservoirs on the annual runoff and sediment load inflows to the TGR based on the data in 1956–2016. The measured sediment load at ...
Abstract null null Mountainous catchments cover a broad range of elevations and their response to a warming climate is expected to vary significantly in space. Nevertheless, studies on climate change impacts typically examine the changes in flow statistics only at the catchment outlet. In this study, we instead demonstrate the high variability of the hydrological response to climate change at the sub-catchment scale, investigating in detail the contribution of all components of the hydrological ...
