Change Detection of Wetland Development with Satellite Data and GIS

Water resources in compare to other matters have a key role in infrastructure development as one of the main physical and land use plans, which has been known. Hurol Azim wetland that is located in southwestern Khuzestan province, bordering Iran and Iraq has about two thirds of its land in Iraq, and one third in the Iranian territory. Wetland water supply sources include: Karkheh River and its tributaries, Mime, Doiraj subsets of Iran and the Tigris in Iraq that are Mashah and Kahla. Landsat satellite images taken by the users in the past years reveal the fact that Hurol Azim wetland area has been smaller in recent decades. The purpose of this study is the wetland changes of TM and ETM + sensor of Landsat imagery in 1990 and 2005. The principal components analysis method was used to determine the aim. Finally, this paper presents changes of wetland by landsat TM and ETM+ in May 1990 and 2000. The result showed that the wetland area of Hurol Azim has been smaller of 515.4 km in 1990 to 230.59 km in 2000. The main reasons for wetland reduced water levels are dam of Karkheh and drought.
