Geomorphological Modeling of the Cross-Sections of the Tigris River Course between Two bridges (Al-Muthanna - Al-Sarafiah) using Remote Sensing Data and Geographic Information Systems

Abstract

This research dealt with the study of cross-sections through the use of a device that analyzes the cross-sections of the Tigris River, a device ((Eight effective cross-sections were measured for a distance) (Son Tak M9)2) km for each section and the width of the stream, the depth of the stream, and the actual amount of water drainage for each section were measured, in addition to extracting the amount of the bottom load in the river course, and after making those measurements, it became clear that the river is approaching the stage of early aging, through the decline in the rates of The velocity of the water current in all sections with the widening in the width of the stream and the emergence of clear sedimentation forms represented by the river islands, which numbered 12 islands in 2022, and differ in terms of their breadth and distance from the banks of the river and take different forms, including round or longitudinal Including what is irregular in shape or stripe. The research aims to show the extent of the impact of the river sections on the different sedimentation processes of the Tigris River in the studied area.
