AbstractThe different values of bifurcation ratios of the six basinal ranks reflect the effect of structural geology and the shape of mam shivan located in( dohuk governorate north east Iraq ). The drainage density of the basin attains a value of (7.28 km/km2). Geomorphological analysis revealed that there are five drainage patterns which are the result of structural and climatic effects. On the other hands the opening phenomenon in the south of the valley is most likely due to structural pattern. Type of the rocks , base level change and vertical incision at (450m) level. The longitudinal valley profile reveals the existence of the four kink point which reflect the adjustment of the valley to the new tectonic activity.
