| Abstract | ||
| The overflow fans are one of the forms that formed in the northwestern and southeastern parts of the Sulaibiyat Depression area. It is located administratively in the southwestern part of Dhi Qar Governorate and the northeastern part of Al Muthanna Governorate, confined between two latitudes (53'' 36' 30o - 35'' 07' 31o) north and arc. Longitude (17'' 28' 45o- 53'' 12' 46o) E. This research relied on geographic information systems programs such as ArcMap 10.6 and on the digital elevation model DEM for the year 2021, and a satellite view of the American satellite Landsat 8, and the most important findings of the research are that there are four river valleys that formed flood fans in the Sulaibiyat Depression area, which is (Al-Ashaali Al-Qusayr, Abu Ghuwair, and Al-Sudair) These valleys originate and run inside Iraqi territory and descend towards the northeast towards the depression, except for Wadi al-Kaseer, which originates from within the Saudi region and flows from the southwest towards the northeast towards the depression. Wadi Al-Kaseer, which is the largest of the valleys, has an area of about (17340.98 km2), Wadi Abu Ghuwair, which is about (216.12 km2), which is the smallest valley in area, and Wadi Al-Sudair, which is about (1286.85 km2), and this means that the larger the area of the valley, the larger the area of its fan. | ||
