The country's topography is generally flat,<ref name="Leonard 2005"/> with the elevation gradually rising as one moves north and east away from [[Lake Chad]]. The highest point in Chad is [[Emi Koussi]], a mountain that rises {{convert|3100|m|ft|0|abbr=on}} in the northern [[Tibesti Mountains]]. The [[Ennedi Plateau]] and the [[Ouaddaï highlands]] in the east complete the image of a gradually sloping basin, which descends towards Lake Chad. There are also central highlands in the Guera region rising to {{convert|1500|m|ft|0|abbr=on}}.

Bordered by Chad, [[Niger]], [[Nigeria]], and [[Cameroon]], Lake Chad currently covers only 1,350 square kilometers, down from 25,000 square kilometers in 1963. The Chari and Logone Rivers, both of which originate in the Central African Republic and flow northward, provide most of the surface water entering Lake Chad. Chad is also next to Niger.
