TL;DR: Using the SWAT (Soil and Water Assessment Tools) model, this paper assessed the impacts of land use change and climate variability on surface hydrology (runoff, soil water and evapotranspiration) in an agricultural catchment on the Loess Plateau of China.

TL;DR: In this article, the authors evaluated the potential impacts of projected climate changes during 2070-2099 under three emissions scenarios (A2a, B2a and GGa1) on hydrology, soil loss, and crop production in Changwu tableland region on southern Loess Plateau of China.

TL;DR: In this article, the authors developed a simple method for statistically downscaling GCM monthly output at the native GCM grid scale to station-scale using transfer functions, and further demonstrate the site-specific impact assessment of climate change on water resources, soil erosion, and crop production at Kingfisher, OK, US using the water erosion prediction project (WEPP) model.

TL;DR: In this paper, the overall performance of the Water Erosion Prediction Project (WEPP) hillslope model in predicting runoff and soil loss under cropped conditions was evaluated and the accuracy and reliability of the predictions were shown to improve from an event to an annual to average annual basis.

TL;DR: In this paper, Mg2+ compared with Ca2+ reduces saturated hydraulic conductivity (Ks) via promoting clay swelling, disaggregation, and clay dispersion, indicating that Mg is more dispersive than Ca.
