TL;DR: This study reviews applicability of game theory to water resources management and conflict resolution through a series of non-cooperative water resource games and illustrates the dynamic structure of water resource problems and the importance of considering the game’s evolution path.

TL;DR: In this paper, high-resolution data enabling identification and analysis of the hydrometeorological causative processes of flash floods have been collected and analyzed for 25 extreme flash floods (60 drainage basins, ranging in area from 9.5 to 1856 km 2 ) across Europe.

TL;DR: In this paper, a modified index accounting for seasonality is proposed for precipitation and streamflow marginals, and a joint deficit index (JDI) is defined by using the distribution function of copulas.

TL;DR: In this article, the authors examined five formulations of potential evaporation, testing for how well each captures the dynamics in evaporative demand, and highlighted the need for spatially and temporally dynamic data describing all drivers of evapore demand, especially projections of each driving variable when estimating the possible affects of climatic changes on evapative demand.

TL;DR: In this paper, the authors present a framework for undertaking climate change impact studies, which can be used for testing the robustness of precautionary climate change allowances used in engineering design, and demonstrate the approach is demonstrated via an assessment of the UK Government's 20% allowance for climate change applied in two contrasting catchments.

TL;DR: In this paper, it was shown that using runoff values from cropped areas is necessary to account for differences in infiltration capacities between vegetated and tilled bare fallow areas, but requires re-evaluation of the crop factors.

TL;DR: The results indicate that coupled wavelet-neural network models are a promising new method of short-term flow forecasting in non-perennial rivers in semi-arid watersheds such as those found in Cyprus.

TL;DR: This paper describes and compares a series of predictive models for forecasting water demand obtained using time series data from water consumption in an urban area of a city in south-eastern Spain, and proposes a simple model based on the weighted demand profile resulting from the exploratory analysis of the data.

TL;DR: In this article, a modelling study carried out to investigate whether the calibrated parameter values for rainfall-runoff models based on historical observed data can be used to reliably predict runoff responses to changes in future climate inputs.

TL;DR: The proposed optimal rainfall forecasting model can be derived from MANN coupled with SSA, and results show that advantages of MANN over other models are quite noticeable, particularly for daily rainfall forecasting.

TL;DR: In this paper, the authors conducted a global hydrological simulation for 15 years from 1985 to 1999 at a spatial resolution of 0.5° × 0.0° (longitude and latitude) and found that the global virtual water export of five crops (barley, maize, rice, soybean, and wheat) and three livestock products (beef, pork, and chicken) was estimated globally.

TL;DR: The main findings of the study are that the parameter posterior distributions generated by the Bayesian method are slightly less scattered than those by the GLUE method, and GLUE is sensitive to the threshold value used to select behavioral parameter sets resulting in a wider uncertainty interval of the posterior distribution of parameters, and a wider confidence interval of model uncertainty.

TL;DR: In the case of the Yellow River basin, the Xiaolangdi Reservoir has been used to increase the grain size of suspended sediment delivered to the sea by ∼90% in the last 60 years as discussed by the authors.

TL;DR: In this paper, a review of previous empirical studies to generate statistical relations between changes in forest cover and the associated changes in snow accumulation and ablation rate is presented, and two simple linear models using forest cover as the sole predictor of changes in SNR are provided, as well as the main sources of variation that prevent the elaboration of more accurate multiple regression models.

TL;DR: In this article, it is hypothesized that groundwater major ions chemistry can be employed to determine the interaction between groundwater and saline water/seawater in costal aquifers, and that there exists a relationship between total dissolved solids with chloride, sodium, magnesium and sulphate concentrations of groundwater.

TL;DR: In this article, the effects of soil type and land use on soil macropore characteristics were investigated using X-ray computed tomography at a voxel resolution of 0.234mm.

TL;DR: In this paper, a method for regional frequency analysis and spatio-temporal pattern characterization of rainfall-extreme regimes (i.e. extremes, durations and timings) in the Pearl River Basin (PRB) using the well-known L-moments approach together with advanced statistical tests including stationarity test and serial correlation check, which are crucial to the valid use of Lmoments for frequency analysis.

TL;DR: In this article, the authors investigated the impact of climate variability and human activity on the inflow into Miyun Reservoir and found that climate impact was responsible for about 55% and 51% of the decrease in reservoir inflow, respectively.

TL;DR: Whereas wavelet decomposition improves the performance of ANN models, bootstrap resampling technique produces more consistent and stable solutions, results obtained indicate that WBANN forecasting model with confidence intervals can improve their reliability for flood forecasting.

TL;DR: In this paper, the authors investigated the relationship between soil water content and plant root indices, and other soil properties, under various land uses in the Liudaogou watershed on the Loess Plateau, China.

TL;DR: In this paper, the influence of climate variation on the availability of water resources was analyzed in the headwaters of the Tagus River basin using two drought indices, the standardized precipitation index (SPI) and the standardized precipitation evapotranspiration index(SPEI), and showed a major change in hydrological-climatic relationships in regulated systems including reservoir storage and outflow.

TL;DR: In this paper, a dynamic control operation model that considers inflow uncertainty, i.e. the inflow forecasting error and uncertainty of the flood hydrograph shape is proposed and developed.

TL;DR: In this article, the authors quantified the virtual water content (VWC) of two of the most important crop types worldwide, temperate cereals and maize, at high spatial resolution (0.5°).

TL;DR: In this article, the authors compared three different substrate types (Pumice, Zeolite and Expanded Clay, all pumice based but named for their distinguishing components) at two different substrate depths (50 and 70mm) in a side-by-side comparison.
