Spatiotemporal variation and tendency analysis on rainfall erosivity in the Loess Plateau of China Hydrol. Res. (IF 2.012) Pub Date : 2020-10-01 Yongsheng Cui, Chengzhong Pan, Chunlei Liu, Mingjie Luo, Yahui Guo
Rainfall erosivity is an important factor to be considered when predicting soil erosion. Precipitation data for 1971–2010 from 39 stations located in the Loess Plateau of China were collected to calculate the spatiotemporal variability of rainfall erosivity, and the long-term tendency of the erosivity was predicted using data from the HadGEM2-ES model. Statistical analyses were done using Mann–Kendall

Potential impact of water transfer policy implementation on lake eutrophication on the Shandong Peninsula: a difference-in-differences approach Hydrol. Res. (IF 2.012) Pub Date : 2020-10-01 Jia He, Jiping Yao, Aihua Li, Zhongxin Tan, Gang Xie, Huijian Shi, Xuan Zhang, Wenchao Sun, Peng Du
Traditional research on lake eutrophication has failed to consider the effect of the South-to-North Water Transfer Project (SNWTP) policy; thus, the difference-in-differences (DID) model, which is usually applied to economic factors, was innovatively introduced to evaluate the effect of such policies on lake eutrophication. Nansi Lake and Dongping Lake in the Shandong Peninsula were selected as the

Succession of phytoplankton in a shallow lake under the alternating influence of runoff and reverse water transfer Hydrol. Res. (IF 2.012) Pub Date : 2020-10-01 Qing Li, Guoqiang Wang, Zhongxin Tan, Hongqi Wang
Both runoff and water diversion can interfere with the physical and chemical environment of a lake and affect aquatic organisms. In this study, previously obtained data were used to analyze the phytoplankton community, water quality, water level, and temperature in Dongping Lake (DPH) before, during, and after the water diversion caused by the South-to-North Water Transfer Project. The results showed

A framework for event-based flood scaling analysis by hydrological modeling in data-scarce regions Hydrol. Res. (IF 2.012) Pub Date : 2020-10-01 Jianzhu Li, Kun Lei, Ting Zhang, Wei Zhong, Aiqing Kang, Qiushuang Ma, Ping Feng
Flood scaling theory is important for flood predictions in data-scarce regions but is often applied to quantile-based floods that have no physical mechanisms. In this study, we propose a framework for flood prediction in data-scarce regions by event-based flood scaling. After analyzing the factors controlling the flood scaling, flood events are first simulated by a hydrological model with different

Response of redox zonation to recharge in a riverbank filtration system: a case study of the Second Songhua river, NE China Hydrol. Res. (IF 2.012) Pub Date : 2020-10-01 Xiaosi Su, Yaoxuan Chen, Hang Lyu, Yakun Shi, Yuyu Wan, Yiwu Zhang
Bank filtration induced by groundwater pumping results in redox zonation along the groundwater flow path. Besides the river water, recharge from other sources can change local redox conditions; therefore, redox zonation is likely to be complex within the riverbank filtration (RBF) system. In this study, hydrodynamics, hydrogeochemistry, and environmental stable isotopes were combined together to identify

Coincidence probability of streamflow in water resources area, water receiving area and impacted area: implications for water supply risk and potential impact of water transfer Hydrol. Res. (IF 2.012) Pub Date : 2020-10-01 Xingchen Wei, Hongbo Zhang, Vijay P. Singh, Chiheng Dang, Shuting Shao, Yanrui Wu
Under changing environment, the feasibility and potential impact of an inter-basin water transfer project can be evaluated by employing the coincidence probability of runoff in water sources area (WSA), water receiving area (WRA), and the downstream impacted area (DIA). Using the Han River to Wei River Water Transfer Project (HWWTP) in China as an example, this paper computed the coincidence probability
