The transfer of sediments through the landscape (sediment connectivity) depends on hydrological conditions. This study aimed at assessing changes in sediment sources engendered under extreme drought. A sediment budget model that considered hillslope sediment connectivity was applied to the Latrobe River catchment (South-east Australia) in a relatively normal period (1990-1996) followed by part ...

Climate science has advanced over decades from an initial focus on the development and use of numerical models of Earth’s climate and compilation of rich networks of observational data, to now being in a position to “detect” and “attribute” specific impacts and events to anthropogenic climate change. Recent analyses have thus established the “fingerprint” of anthropogenic climate change in an i...

Droughts affect human well-being and the economy of countries across world. Understanding long-term evolution droughts within a particular region will help in drought mitigation adaptation plans, thereby reducing impact on environment. This study examined multidecadal trends hydrological at two stations along River Niger using 3-month, 6-month, annual time scales. Hydrological events were ident...

Drought events develop in both space and time and they are therefore best described through summary joint spatio-temporal characteristics, such as mean duration, mean affected area and total magnitude. This paper addresses the issue of future projections of such characteristics of drought events over France through three main research questions: (1) Are downscaled climate projections able to si...

Most of the water used for development main socio-economic activities in Central-Western Argentina (CWA), an arid to semi-arid region, home most Argentinean wine production, relies on surface streamflow from several snow-fed rivers. During last decade (2010-2020), reduced snow accumulation over higher elevations Andes mountains triggered occurrence hydrological drought CWA, affecting winter tou...
