TL;DR: Five uncertainty analysis procedures for watershed models are compared and if computationally feasible, Bayesian-based approaches are most recommendable because of their solid conceptual basis, but construction and test of the likelihood function requires critical attention.

TL;DR: In this article, two multivariate statistical methods, hierarchical cluster analysis (HCA) and principal components analysis (PCA), were applied to a subgroup of the dataset to evaluate their usefulness to classify the groundwater samples, and to identify geochemical processes controlling groundwater geochemistry.

TL;DR: In this paper, the potential impacts of climate change and continued urbanisation on waste and stormwater flows in the combined sewer of central Helsingborg, South Sweden, have been assessed using a series of DHI MOUSE simulations run with present conditions as well as two climate change scenarios and three progressive urbanisation storylines.

TL;DR: In this paper, the impact of climate change on the hydrology of the Chute-du-Diable watershed (Quebec, Canada) is studied by comparing statistics on current and projected future discharge resulting from a wide range of different climate change scenarios.

TL;DR: Wang et al. as discussed by the authors used the non-parametric Kendall test and the Pettitt test to identify trends and change points in the annual streamflow over the past 50 years.

TL;DR: In this paper, the authors proposed a new approach for integrating the quasi-distributed watershed model, SWAT, with the fully distributed ground-water model, MODFLOW, where the characteristics of the hydrologic response units (HRUs) in the SWAT model are exchanged with cells in the MOD FLOW model.

TL;DR: In this paper, the authors proposed a procedure to improve the estimations of freshwater availability at subbasin level and monthly intervals by applying the distributed hydrological model "Soil and Water Assessment Tool" (SWAT).

TL;DR: In this article, the authors evaluate a threshold-based flash flood warning method, by considering a wide range of climatic and physiographic conditions, and by focusing on ungauged basins.

TL;DR: Wang et al. as discussed by the authors investigated spatial and temporal patterns of trends of the precipitation maxima (defined as the annual/seasonal maximum precipitation) in the Yangtze River basin for 1960-2005 using Mann-Kendall trend test, and explored association of changing patterns of precipitation maximima with large-scale circulation using NCEP/NCAR reanalysis data.

TL;DR: In this article, an innovative approach is presented which incorporates remote sensing derived evapotranspiration in the calibration of the Soil and Water Assessment Tool (SWAT) in a catchment of the Krishna basin in southern India.

TL;DR: In this paper, the authors evaluated the ECH 2 O sensors for measurement of soil moisture content, bulk electrical conductivity (EC b ), and temperature across a range of soils, across a measurement frequency between 5 and 150MHz.

TL;DR: In this paper, the effects of droughts on the water quality of the river Meuse in western Europe, based on analysis of existing water quality data, were assessed and compared to water quality during reference periods.

TL;DR: In this paper, the Shannon entropy method, Mann-Kendall method and linear fitted model were applied to investigate the spatial and temporal patterns of trends of the precipitation in the Yellow River Basin (YRB) during 1960-2006.

TL;DR: In this article, the authors evaluate the rainfall estimates of the Tropical Rainfall Measuring Mission (TRMM) satellite over the Tapajos river basin, a major tributary of the Amazon.

TL;DR: In this paper, a fully coupled numerical model is proposed to solve the governing equations for liquid water, water vapor, and heat transport in bare soils, and the numerical model with detailed measurements of soil temperature, heat flux, water content, and evaporation from the surface, and different formulations for the soil surface resistance parameter and test their effect on soil water content near the surface.

TL;DR: In this paper, the Soil and Water Assessment Tool (SWAT) model was re-conceptualized to distribute overland flow in ways consistent with VSA hydrology by modifying how the Natural Resources Conservation Services (formerly Soil Conservation Service) curve number (CN) and available water content were defined; the new modeling approach is called SWAT-VSA.

TL;DR: This article provides an extended response to the criticisms of the GLUE methodology by Mantovan and Todini and shows that the formal Bayesian identification of models is a special case of GLUE that can be used where the modeller is prepared to make very strong assumptions about the nature of the modelling errors.

TL;DR: In this paper, a study was conducted on the effectiveness of green roofs to mitigate stormwater using computer simulation, and the stormwater performance was simulated for a modular block green roof using a packaged soil moisture simulation, HYDRUS-1D, with simulation results verified by study site data.

TL;DR: In this article, the authors investigated historic changes in seasonal patterns of streamflows, by comparing mean monthly flows and analyzing cumulative hydrographs over the periods of record of about a century.

TL;DR: In this article, a combined hydrogeologic and isotopic investigation using several chemical and isotope tracers was carried out in order to determine the sources of water recharge to the Souss-Massa basin, the origin of salinity, and the residence time of water.

TL;DR: Assessing for the UK, whether the current use of cytotoxic drugs, one of the most toxic pharmaceuticals in common use, could pose a risk to aquatic organisms and to humans through water recycling finds grounds for optimism on removal of these compounds.
