The research aims to detect changes in the characteristics of landforms for the Euphrates Valley within the boundaries of the search area and the factors the causative her to found and atherzlk on population and economic their activities
‎ The sinuosity ratio of the stream was 1.51 in 1990 and increased in to 1.53 in 2010. The number of ‎islands in the area under study was 29 island for both years 1990 and 2010 .

In the 2010 the number of oxbow lakes ‎decreased in to two, by disappearance of Sarat Alyehoodi .
These changes in landforms influenced ‎ on human activities ‎including irrigation, agriculture and roads as well as environmental impacts
