Au Sahel, sous 500 mm de pluie annuelle, l'érosion éolienne constitue un facteur important de la dégradation de l'environnement. Elle cause des pertes en terre et réduit la productivité des sols. Ce travail, conduit dans le Sud-Ouest du Niger, v

International audience; In the Sahel, under 500 mm of annual rainfall, wind erosion is an important factor leading to the degradation of the environment. It causes soil losses and reduces soil productivity. This work, conducted in the southwestern Ni

How long does precipitation inhibit wind erosion in the Sahel ? [+ supporting information]

Autor: Bergametti, G., Rajot, Jean-Louis, Pierre, C., Bouet, Christel, Marticorena, B.

Simultaneous measurements of saltation, wind speed, and rainfall performed in Niger before, during, and after 18 rain events are used to investigate how rain events affect wind erosion in the Sahel. The results show that the inhibition of saltation i

The impact of model horizontal grid spacing on meteorology and dust emissions in the Bodélé depression was investigated during the well-documented period of the Bodélé Dust Experiment 2005 (BoDEx 2005). Five horizontal grid spacing ranging from 1
