TL;DR: In this article, the authors investigated the impact of climate variability and human activities on streamflow decrease in three catchments located in different parts of the Haihe River basin (HRB), namely, Taolinkou, Zhangjiafen and Guantai catchments.

TL;DR: In this paper, a new trend detection method for hydrological studies is explored, which involves the use of wavelet transforms (WTs) in order to separate the rapidly and slowly changing events contained in a time series.

TL;DR: In this paper, the potential of support vector machines (SVM), adaptive neuro-fuzzy inference system (ANFIS), multiple linear regression (MLR) and multiple non-linear regression (MNLR) for estimating ETo were investigated using six input vectors of climatic data in a semi-arid highland environment in Iran.

TL;DR: In this paper, the authors compared three widely used satellite precipitation products with a dense rain gauge network in the Mishui basin (9972 km 2 ) in South China and then optimally merged their simulated hydrologic flows with the semi-distributed Xinanjiang model using the Bayesian model averaging method.

TL;DR: In this article, a statistical and temporal stability analysis is employed to assess the space-time variability of soil moisture at local and catchment scale, and the feasibility to use coarse resolution data for hydrological applications in small to medium sized catchments is confirmed.

TL;DR: The results demonstrated that marsh soils in both marshes had higher silt and total P contents, higher bulk density and lower sand contents after the flow-sediment regulation; moreover, soil salinity was significantly decreased in the tidal salt marsh As and Cd concentrations were significantly higher in both marsh soils after the regulation than before, and there were no significant differences in the concentrations of Cu, Pb and Zn measured before and after the regulations as discussed by the authors.

TL;DR: In this paper, the authors analyzed different rainfall interpolation schemes with regard to their suitability to produce spatial rainfall estimates in a monsoon dominated region with scarce rainfall measurements and found that the choice of the covariate had a significant impact on precipitation and runoff amounts, as well as on the temporal course of runoff events.

TL;DR: The comprehensive reviews on the use of various programming techniques for the solution of different optimization problems have been provided and conclusions are drawn where gaps exist and more research needs to be focused.
