Abstract:
... We present our research on the Prato Casarile landslide dam in Genoa city to illustrate the interactions between slope instability processes and structural stabilization interventions aimed to reduce the hazard in a densely-populated area. Analysis of the degradation of structural interventions constructed after flood events in 1953, 1970 and 2014 contributed to an improved mitigation strategy. At ...

Abstract:
... The Tarim River Basin (TRB) is an extremely arid area in China, suffering from dry climate and intense human activities, which have brought about significant changes in ecological processes and then, led to serious ecological vulnerability (EV). This study proposes an assessment framework to evaluate EV and analyze its dynamic change in the TRB during 2005–2015. An integrated method is developed w ...

Abstract:
... Uncertainties in watershed modeling need to be addressed to increase predictive accuracy and enhance model interpretation. Nevertheless, event-based characteristics incorporating management concerns were rarely considered in the sediment modeling within an uncertainty assessment framework, which might lead to biased decision makings in watershed management. In this study, the event-based likelihoo ...
... The Segura basin in south-eastern Spain is one of the most water-scarce regions in Europe. Its water economy has characteristics that constitute very favourable conditions for water market activity, and there are significant trading opportunities. However, the traded volumes have been rather small even though most of the water market activity in continental Spain is concentrated there. This paper ...

... This study analyses the differences in significant trends in magnitude and frequency of floods detected in annual maximum flood (AMF) and peak over threshold (POT) flood peak series, for the period 1965–2005. Flood peaks are identified from European daily discharge data using a baseflow-based algorithm and significant trends in the AMF series are compared with those in the POT series, derived for ...
... In this study, the spatial variation of daily and monthly concentration precipitation index and its aggressiveness were used in 23 rainfall stations in the extreme north-east of Algeria over the period 1970–2010. The trend was analysed by the Mann–Kendall (MK) test. The results show that daily precipitation concentration index (CI) values are noticeably higher in places where the amount of total p ...

Abstract:
... Many of the traditionally used hydrological models have complex formulations and require several input variables over time and space, which are generally scarce and expensive for obtaining, especially in developing countries. In order to overcome these limitations, the Lavras Simulation of Hydrology has been developed and successfully applied to Brazilian basins. The most recent advances of the mo ...

Abstract:
... Macro-scale river-routing schemes first emerged to channel runoff generated as a by-product from land surface models to oceans. In the past decade, as discharge of major rivers was identified as a suitable parameter to test the performance of the macro-scale land surface models, river-routing received significant attention, with development of multiple schemes. As resolution improves, the possibil ...
... The authors discovered an error in the discharge calculation for the mire outlet stream (MC4) that led to an underestimation of nitrogen (N) export from this catchment. This error has no influence on the overall message or conclusions of the paper but does suggest even greater relative N losses from the mire-dominated catchment. ...
... This article examines the power interplay that shapes the transboundary water interaction in the Brahmaputra River basin. The article provides two key insights based on data sharing and bilateralism aspects. First, the lack of a standard, hydrological data-sharing mechanism has created a sense of mistrust between riparians. Second, bilateralism and power asymmetry between the riparian countries ha ...
... The specific features of formation of maximal water levels in the lower Amur R. are studied. They are correlated with streamflow formation factors in different parts of the Amur Basin and Zeya R. flow regulation. Water level variations in high-water season of the year were analyzed for 1955−2013, including the periods of natural runoff variations (1955−1979) and after the start of Zeya Hydroengine ...

Abstract:
... The uptake of nitrogen (N) and phosphorus (P) by plants in riparian zones can significantly decrease the water pollution risk. Moreover, the vegetation area in riparian zone can be impacted by raising of water level and afforestation. As the largest reservoir in North China, the Miyun Reservoir is affected by the South-to-North Water Transfer (SNWT) and large-scale afforestation. However, few effi ...

Abstract:
... Fifty-one monitoring stations from the Water Framework Directive network (2000/60/CE) were selected in the Adour-Garonne basin (117,650 km², SW France). These stations were characterized by a diversity of land use, implying different water pesticide contamination profiles. In each, Polar Organic Chemical Integrative Sampler (POCIS) deployment (14 days) and grab water samples (1 per period) were pe ...

Abstract:
... Identification and characterization of a relict landscape in the Black Hills of South Dakota has provided insight into the postuplift history (~30 Ma to present). A new watershed decomposition technique has been developed that utilizes high-resolution digital elevation models and traditional long valley profiles to identify the location and extent of the relict landscape as well as its geomorphic ...

Abstract:
... Accurate and continuous precipitation amount and spatiotemporal distribution data are essential for water resource management, flood forecasting, and simulation of hydrological processes. Satellite-based precipitation products (SPPs) with high spatio-temporal resolution have been shown to represent a potential alternative data source for ungauged regions. The objective of this study was to evaluat ...

... Over the last five decades, the Athabasca River Basin in Alberta, Canada, has been subjected to a wide range of environmental stressors from diverse human developments. This has resulted in an escalation of government, academic, industry and community-based monitoring and research efforts. However, despite all the attention received, a comprehensive synthesis of what has been studied is lacking, i ...
