| dc.description.abstractEn | A hydrological perspective to the recent sedimentary analysis conducted at Lake Yoa (Ounianga region, NE Chad) is proposed. The complex hydrological and hydrogeological situation alters the climatic stress. The potential paleo-water network and lake levels have been computed based on SRTM elevation information and ArcGis software. Results show that Lake Yoa is situated in a favorable location, and in addition to continuous input from the Nubian Sandstone Aquifer System (NSAS), it could benefit from river input from distant recharge areas, including the Tibesti Mountains and a large catchment area in the Erdis. Water budgets for 6000 cal yr BP reconstructed conditions show that the maximum lake level (40m above its present level) was probably maintained relatively easily by surface and subsurface water. | |
