Geomorphic Changes in Morphometric Significance for the Stream of the Euphrates River between Fallujah Dam and Bzeibiz Bridge

Abstract

The study showed by comparing the stream of the Euphrates River with three time periods (1972-1997-2022) to highlight and analyze the geomorphic changes that there were changes in the dimensions of the main course (the width and length of the course), as the length of the course of the Euphrates River from the Fallujah Dam to the Bzeibiz Bridge reached (52.78 km). In 1972, while its length decreased in 1997, reaching (51.92 km) with a decrease in capacity (0.86 km), while the length of the stream increased in 2022, reaching (52.47 km), with an increase of (0.55) over 1997. The reason for these changes is due to natural and human factors.

          The study also showed a change in the numbers and dimensions of river bends and turns, as it revealed the presence of (6) bends and (4) bends in 1972 and (5) bends (5) bends for the years 1997 and 2022. Detour The width and length of the stream in the bend and twist.

           It became clear through the study a change in the dimensions, numbers, characteristics and area of the islands during the study periods. The number of riverine islands reached (11) in 1972, then the number increased to (22) riverine islands in 1997, then the number decreased to (14) in 2022.
