Morphotactic analysis of Tayat Anah and its impact on the variation in the shape of the Euphrates River channel in western Iraq

Abstract

It is evident from a review of satellite images that the course of the Euphrates River was affected within the confined area between the Iraqi-Syrian border in the west and Haditha Lake in the east by a number of geological structures, the most important of which is the growth of a sub-surface fold, which worked to change the features of the riverbed and led to the presence of severe anomalies in it. A fold of it based on some morphological and geomorphological indicators through which it is possible to detect the presence of tectonic activity affecting the straightness of the river course within the studied section between the Iraqi-Syrian border and a modern lake, so this study aims to clarify the effect of the growth and aggravation of a fold about it, whose presence indicates the activity of neotectonic. which led to a change in the course of the Euphrates River from the direction (northwest - southeast) to (east northeast - west southwest), relying on the digital elevation model. DEM)) and the information systems program (Arc Gis10.8) in applying these indicators. The study showed a tectonic effect on the river section through the morphological anomaly of the main waterway.
