Chad Basin outline. The Chad Basin is the largest endorheic basin in Africa, centered approximately on Lake Chad.It has no outlet to the sea and contains large areas of semi-arid desert and savanna. The drainage basin is approximately coterminous with the sedimentary basin of the same name, but extends further to the northeast and east.. The . During the Holocene a giant lake, known as Lake Mega-Chad (LMC), extended over more than 350,000 km 2 in southern Sahara. Morphodynamic features of sedimentary systems outlining the LMC palaeoshorelines have been identified by the joint analyses of new topographic images (Digital Elevation Model) acquired by radar .
Lake Chad is regarded as the remainder of an inland sea, a paleolake referred to as Mega-Chad, which existed around 5,000 BC. With a surface area of 1,000 000 km2, it was the largest of the four existing paleolakes in the Saharan region. The African manatees which were discovered in the inflows of the lake support this theory. At its peak around 6,000 years ago, Palaeolake Mega-Chad was the largest freshwater lake on Earth, with an area of 360,000 km 2.Now today's Lake Chad is reduced to a fraction of that size, at only .
In the Chad Basin, several lacustrine episodes are identified during the Quaternary (Maley, 1977; Servant and Servant-Vildary, 1980).Based on the endoreic character of this intracratonic basin (Burke, 1976) and on the identification of long sandridges surrounding widespread lake deposits (Schneider, 1967), a Holocene Lake .
Relationships between Lake Mega-Chad level, lake surface and lake volume. Curves are given from 285 m, the level above which the northern and southern sub-basins are connected through the Bahr el Ghazal outlet. A clear inflexion between the 300 and 305 m lake levels is observed within the hachured area which represents the . Holocene Lake Mega-Chad (LMC) was the largest late Quaternary water-body in Africa. The development of this giant paleo-lake is related to a northward shift of the isohyetes interpreted as evidence for an enhanced Monsoon (African Humid Period). Numerous preserved coastal features have been described all around the LMC shore.About 7,000 years ago, a vast lake spread hundreds of square kilometers across north-central Africa. Known to scientists as Lake Mega Chad, it covered more than 400,000 square kilometers (150,000 square miles) at its peak, making it slightly larger than the Caspian Sea, the biggest lake on Earth today. Modern Lake Chad has shrunk to just a .Lake Chad is the remnant of a much vaster lake known as Mega-Chad which 22,000 years ago drained a greener Sahara and was three times the size of Lake Victoria, now Africa’s largest lake.

The Chad Basin is an intracratonic sag-basin located in North Central Africa (Burke, 1976, Hartley and Allen, 1994) (Fig. 1). The basement rocks of this basin are represented by crystalline rocks related to the Pan-African orogeny (ca. 750–550 Ma) (Kusnir and Moutaye, 1997). Above a Late . North Africa was wetter 15,000–5,000 years ago than today, with wetlands and lakes formed in the Sahara due to an enhanced monsoon. We reconstruct the lake-level history of Lake Mega-Chad, when it was the largest African lake, and demonstrate that this humid period ended abruptly 5,000 years ago, indicating that the African . The existence of Lake Mega-Chad has been debated for a long time (Tilho, 1925). However, today, this palaeolake is wrongly neglected in palaeoenvironmental reconstruction from the regional to the global scale. This study gives conclusive evidence for a Holocene Lake Mega-Chad and outlines its shoreline. Wave processes are proposed .
The Sahara was wetter and greener during multiple interglacial periods of the Quaternary, when some have suggested it featured very large (mega) lakes, ranging in surface area from 30,000 to 350,000 km 2.
