Morphometrics of the river bends between the two bridges (Al-Muthanna and Sarafiya) of the Tigris River

Abstract

     This research deals with the study of the dimensions of the river bends of the Tigris River and the measurements of those dimensions by comparing the stages of the years (1980-2000-2022) between the two bridges (Al-Muthanna - Al-Sarafia) as the river approaches in the early stage of maturity.  The activity of the process of erosion and sedimentation during those time stages, which led to a morphometric change in the criterion of meandering ratio and an increase in the activity of the process (sculpting) of the turns that differ in terms of their breadth and distance from the banks of the river.  The banks retreated, in addition to measuring the criterion of range and direction, knowing the direction and the degree of deviation, by measuring the straight distance between the bend and the middle of the length of the bend.  And the nature of the slope of the surface, in addition to the speed of the current, which determines the activity of geomorphological processes, including (sculpting and sedimentation).
