Abstract

In this study, the Euphrates river bed was studied using a geomorphological indicator in terms of its length and capacity. The changes that occurred in the natural phenomena from the course, which included the turns, the river islands and the flow velocity between 1985 and 2017, This was done using (Arc GIS 10.3) and satellite imagery .In the study, the following results were obtained: the curves were characterized by the zigzag and the change of the length of the riverbed from 2,179 to 16,181. In terms of capacity, after selecting 15 sites, some sites were reached towards widening and the other narrow. In addition to the islands, the number of islands increased to 42 after 31 during the time period mentioned above. The changes in the flood plain increase the area on the left side and decrease it on the right side.
