Moteurs et conséquences de la resuspension dans un lac sahélien peu profond : le lac de Guiers au Sénégal

Abstract: International audienceLa dynamique des particules dans les systèmes aquatiques est régit par l’interaction entre la resuspension et la sédimentation. Cette étude est consacrée à la détermination des processus responsables de la resuspension des particules dans le lac de Guiers situé au nord du Sénégal. Des échantillons ont été collectés au cours d’un cycle annuel au niveau de trois stations prises dans la partie centrale du lac. Dans ce site, la resuspension des particules est liée à l’action des vents mais au… Show more

“…Wind-driven resuspension in shallow lakes has been reported in different areas [41], including the Sahel. Sané et al [42] pointed out its impact for the Guiers Lake in Senegal, which is 2 m deep on average. The maximum depth for the Agoufou Lake and other lakes in the Gourma area is typically a few meters and the depth regularly decreases toward the shoreline.…”
