Geomorphic changes of Karoon River Course, Using RS and GIS Data(The Reach of Shoushtar to Arvandrod)

The Existence of important agricultural structure, civil, industrial and urban projects, needs of the sides of Karoon river, damages of geomorphologic changes, wide change of the meander in rout of the river and the role of them in natural Changes as well as the economical and social ones are the theories of survive of the intensity, type and amount of changes on Karoon river. The case study area is a part of Karoon river located in Khuzestan province in southwest of Iran. The length of this reach is about 364 km from the north of Shoshtar to the Arvandrod. In this research by using of satellite images (Land sat, IRS, Terra), GIS layers, Arial photos and field studies of the changes in Karoonriver have been survived. In this reach the geomorphologic changes have been analyzed during a period of 52 years from 1955 to 2007. The purpose of this research is ecognizing the most important geomorphologic land forms of the Karoon river sides and determining the amount of the changes during the study. The results show that the rate of changes and the length of river channel have been increased.
