TL;DR: In this article, the combined effect of land use and climate changes on hydrology for a 486 km 2 catchment in Denmark and to evaluate the sensitivity of the results to the choice of hydrological model.

TL;DR: In this paper, a comprehensive assessment of changes to the sustainability of the water resource system in the city of Bayannur was conducted using these indicators, which indicated that there is an increase in the driving force of local water consumption due to changes in society, economic development, and the consumption structure of residents.

TL;DR: In this article, the model HYDRUS-1D, coupled with the FAO-56 dual crop coefficient approach (dualKc), was applied to simulate the water and salt movement processes.

TL;DR: In this article, two multiscalar drought indices (SPI and SPEI) were used to identify the regional spatiotemporal characteristics of drought conditions from 1957 to 2012.

TL;DR: In this article, numerical simulation using the finite difference method (FDM) was conducted to analyze the effects of pumping in the pit, and the FDM results showed that drawdown varies along the depth of the confined aquifer.

TL;DR: In this article, the effects of biochar concentration and particle size on hydraulic conductivity (K ) and dissolved organic carbon (DOC) in leachate were assessed. And the authors found that the decrease of K associated with coarser biochar was caused by the bimodal particle size distribution.

TL;DR: In this article, the authors evaluated the relative potential of spatially distributed surface and root zone soil moisture estimates in calibration of Soil and Water Assessment Tool (SWAT) toward improving its hydrologic predictability with reduced equifinality.

TL;DR: In addition to flood incident reports, valuable hydraulic data such as the extent and depths of inundated areas and flow rate estimates can be computed using messages, photos and videos produced by citizens as mentioned in this paper.
