The study of arvand delta changes by use of RS, GIS and fuzzy logic since 1989 to 2007

Sea-level changes are a complex function of global, regional and local influences. These changes affect coastlines, form deltas and develop characteristic of it. Deltas are influencing by marine and fluvial currents where intersection point between them on costs show different type of changes. In this paper by using of satellite images (TM, ETM+ and LISSIII), GIS layers, RS techniques, field studies and fuzzy logic the changes of northwest delta of Persian golf has been survived. The study area has been formed by fluvial sediments of the Karoon, Euphrates and Tigris rivers. During the late decades because of physical and artificial parameters the study area are showing a lot of changes that are important in many fields. The purpose of this paper is recognizing the most important changes of arvand delta and determining amount of changes since 1989 to 2007. The results made will be discussed in the text paper.
