Over the last decades, sea surface temperature (SST) reconstructions based on the Mg/Ca of foraminiferal calcite have frequently been used in combination with the δ18O signal from the same material, to provide estimates of δ18O of the water (δ18Ow), a proxy for global ice volume and sea surface salinity (SSS). However, because of error propagation ...
Future climate scenarios for the Mediterranean region indicate a possible decrease in annual precipitation associated with an intensification of extreme rainfall events in the coming years. A major challenge in this region is to evaluate the impacts of changing precipitation patterns on extreme hydrological events such as droughts and floods. For t...
The objective of this study is to model discharge and solid erosion quantification through a small agricultural watershed by applying the SWAT model (Soil and Water Assessment Tools) on the Wadi Harraza's basin of which is part of Wadi Cheliff's basin, with an average altitude of 500 m, drains an area of 568 sq km. Soil and Water Assessment Tool (S...
African cities are prone to recurrent flooding due to unfavorable rainfall conditions, often insufficient drainage infrastructure and fast and poorly controlled urban development. It is thus important to put forward efficient tools to characterize flooding and its consequences over large urban areas, e.g. the entire agglomeration. However, scarce d...
Spectral unmixing refers to the process by which the spectrum measured over a mixed target is decomposed into a collection of pure component spectra called endmembers and their fractional abundances. Mixed targets are frequently encountered in remote sensing and spectral unmixing techniques have been mostly developed for visible and near-infrared (...
