'''Khatt Atui''' is a [wadi](/source/wadi) in [North Africa](/source/North_Africa). This dry riverbed begins near [Aousserd](/source/Aousserd) in the disputed territory of [Western Sahara](/source/Western_Sahara) and runs southwest through the [Dakhlet Nouadhibou](/source/Dakhlet_Nouadhibou_Region) and [Inchiri](/source/Inchiri_Region) [Regions of Mauritania](/source/Regions_of_Mauritania),<ref>{{cite map |url=http://legacy.lib.utexas.edu/maps/tpc/txu-pclmaps-oclc-22834566_j-1b.jpg |title=TPC J-1B: El Memrhar, Mauritania |series=Tactical Pilotage Chart |scale=1:500,000 |publisher=Defense Mapping Agency Aerospace Center |date=1985}}</ref> ending at the Baie d'Aouati on the Atlantic coast east of [Iouik](/source/Iouik), [Mauritania](/source/Mauritania) in [Banc d'Arguin National Park](/source/Banc_d'Arguin_National_Park).<ref>{{cite map |url=http://legacy.lib.utexas.edu/maps/ams/west_africa/txu-oclc-6595921-ne28-2.jpg |title=NE 28-2: El Memrhar, Mauritania |series=Series G504 |scale=1:250,000 |publisher=U.S. Army Map Service |date=1963}}</ref>

Khatt Atui has been suggested as the location of the lower reaches of a major ancient river, dubbed the [Tamanrasett paleoriver](/source/Tamanrasset_River), that flowed through the Sahara to the [Arguin Basin](/source/Bay_of_Arguin) during humid episodes in the late [Quaternary](/source/Quaternary).<ref>{{cite journal |date=2015 |title=African humid periods triggered the reactivation of a large river system in Western Sahara |doi=10.1038/ncomms9751 |journal=[Nature Communications](/source/Nature_Communications)|pmc=4659928 |pmid=26556052 |volume=6 |page=8751  | last1 = Skonieczny | first1 = C | last2 = Paillou | first2 = P | last3 = Bory | first3 = A | last4 = Bayon | first4 = G | last5 = Biscara | first5 = L | last6 = Crosta | first6 = X | last7 = Eynaud | first7 = F | last8 = Malaizé | first8 = B | last9 = Revel | first9 = M | last10 = Aleman | first10 = N | last11 = Barusseau | first11 = JP | last12 = Vernet | first12 = R | last13 = Lopez | first13 = S | last14 = Grousset | first14 = F}}</ref> Early [Neolithic](/source/Neolithic) archaeological sites have been found along the Mauritanian portion of the wadi.<ref>{{cite web |title=Tasiast Gold Mine Expansion Project: Phase 1b Environmental Impact Assessment |url=https://www.miga.org/Documents/SPGDisclosures/Phase%201b%20Environmental%20Impact%20Assessment%20Supporting%20Infrastructure%20and%20Preliminary%20Upgrades%20-%20URS%20Scott%20Wilson%20-%20July%202011.pdf |publisher=[URS Scott Wilson](/source/URS_Corporation) |page=122 |date=31 July 2011 |accessdate=4 February 2018}}</ref>
