Abstract

Sedimentary geomorphological features are formed as a result of the process of erosion and river sedimentation of the valley of Euphrates River are formed within the study area extending within the sedimentary plain in Anbar Governorate, as the sedimentary features are formed as a result of the slow water current of the Euphrates River. The reason for this is the low slope of the river course and the variation in the amount of water drainage between the months and seasons of the year, as the river load is deposited in the shallow areas of the river course and in different forms and extensions. When plants grow on it, especially reeds and papyrus plants, which are characterized by their rapid growth, in addition to other plants that have strong roots contribute to the stabilization of the nucleus of the river islands within the course of the river. While the archetypes begin to form in conjunction with the decrease in the slope of the Euphrates River, which represents the beginning of the approach of the Euphrates River from the level of its base, as the vertical erosion is reduced and the lateral erosion plays a more important role in the formation of some land features such as river bends and torsions, which are formed as a result of the nature of the gradual slope of the river, which begins with the sculpting of these sides forming bends along the stream. Among the most sedimentary forms, the most important of which are within the stream of the river are the phenomenon of meandering river and turns, the phenomenon of river islands and plain lands. The number of meandering river reached six river torsions,  while the number of river bends reached three river bends
