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.

Chad’s waterways consist primarily of three main bodies of water: the Logone and Chari rivers, and Lake Chad. Despite the importance of Chadian waterways to economic activity and cross-border trade, there is no organized river and or lake transportation network.

It is the main source of water of Lake Chad, which is located at the junction of four countries: Nigeria, Niger, Chad, and Cameroon. [2] The Chari River flows from the Central African Republic through Chad into Lake Chad, following the Cameroon border from N'Djamena, where it is joined by its western and principal tributary, the Logone River.

During the wet season, the Chadian waterway transport system consists of two rivers in the south, the Chari and Logone. The Chari runs about 1200 Km from the southeast to the Lake Chad region. While the Logone runs about 1000 km from north to south where it meets the Mbere river and enters Cameroon.

Lake Chad is a terminal depression with the seven basin countries grouped around it, of which four are in direct contact with the lake: Nigeria, Niger, Chad and Cameroon. In Nigeria, two sub-basins drain into the lake: • the Yedseram/Ngadda sub-basin to the south; • the Hadejia/Jama'are-Komadougou/Yobe sub-basin to the north.

2004年11月10日 · Chad's major rivers are the Chari and the Logone and their tributaries, which flow from the southeast into Lake Chad. Both river systems rise in the highlands of Central African Republic and Cameroon, regions that receive more than 1,250 millimeters of rainfall annually.

The Lake Chad Basin in southern Chad is one of the largest sedimentary groundwater basins in Africa. It includes three main aquifers: an upper, unconsolidated Quaternary/Pliocene aquifer of lacustrine and deltaic deposits (the Chad Formation); a Tertiary sequence underlying this (the Continental Terminal formation); and a basal aquifer of ...

The Lake Chad basin, located in Northern Central Africa, covers almost 8% of the continent and spreads over seven countries. It is shared among the countries of Algeria, Cameroon, Central African Republic (CAR), Chad, Libya, Niger, Nigeria, Sudan, Algeria and Libya.
