  abstract = {{I}n the 2,500,000 km(2) {L}ake {C}had {B}asin in central {A}frica, the 2000 {S}huttle {R}adar {T}opographic {M}ission ({SRTM}) data have been used to supplement the existing topographic data. {SRTM} data produce much sharper images of the region's topography and provide new insights into debates about the nature and extent of late {Q}uaternary {L}ake {C}had. {T}his paper shows that the accuracy of {SRTM}30, the recently released 30 arc seconds topographic data from {SRTM}, largely surpasses that of previous global {D}igital {E}levation {M}odels ({DEM}s) available in the region. {U}sing a {GIS} we identified from {SRTM}30 elevation data key features in the landscape topography providing further evidence for the existence of a {M}egalake {C}had. {T}he {SRTM}30 data corroborate the presence of two ancient shorelines associated with stillstands of the paleolake at the elevation of the {M}ayo {K}ebbi and {B}ahr el {G}hazal spillovers. {W}e found a general flattening of the topography in the region covered by {M}egalake {C}had which is most likely the result of wave-cut action. {T}he {SRTM}30 data show that the remains of the highest paleoshoreline have a constant elevation of 325 +/- 5 in amsl. {A}t its maximum extent, {M}egalake {C}had had an area of about 340 000 km(2) (only 8% less than the present-day world's largest lake, the {C}aspian {S}ea). {T}he {SRTM}30 data also revealed ancient drainage networks in the {S}ahara that lead to {M}egalake {C}had. {W}e compiled available 14 {C} dates to constrain {H}olocene {M}egalake {C}had events. {T}he results presented in this paper have significant consequences for improving our knowledge of regional paleohydrology and continental climate change. {T}his study is also the first step for a {GIS}-based reconstruction of late {Q}uaternary paleohydrology in tropical {A}frica.
