Some of the previously formed folds deformed by the Sarvestan fault (~78 km length) with dominant strike-slip movements, which is cutting across the Zagros fold-thrust belt
The river is located in the Zagros fold-thrust belt
and Karkheh basin is divided to 35 sub- basin(Figure 2).
The Zagros fold-thrust belt covers most of the Iraqi Kurdistan Region; it contains fold structures with Cretaceous limestone outcropping in the anticlinal cores and Tertiary limestones and clastics on its flanks (Jassim and Buday, 2006) (Figure 3).
The Zagros fold-thrust belt involve gigantic anticlinal traps, with fracturing producing well connected hydrocarbon reservoirs and groundwater aquifers (Beydoun et al., 1992).

On the basis of lateral facies variations, the Iranian Zagros fold-thrust belt
is divided into different tectonostratigraphic domains that are from SE to NW: the Fars Province or eastern Zagros, the Khuzestan province or Central Zagros and finally the Lurestan Province or Western Zagros [44.45] (Fig.
