Evaluation of coastal geomorphologic change in northern coast of Persian Gulf from Kangan Port to Ziyarat Estuary using remote sensing and GIS

Coastal geomorphological changes in the short-term and long-term are observable in all coastal areas. The changes occur to reach the balance in this region. Aware of these changes is very important to geomorphologists, environmental planners to help them to solve coastal problems. The purpose of this study is to assess the geomorphologic changes occurring in the region of coastal Bushehr Port Kangan place within the Ziarat estuary. In this study multi-temporal satellite images of Landsat were selected as the data base. The principal component analysis and fuzzy logic are used for monitoring and evaluating the geomorphological changes. Results of this research show that during the 21 year research period from 1986 to 2006 most important factor changing landforms and coastline in the region are changes water level of the Persian Gulf that cause to submerged about 46 square kilometers of the region's coastal zone land. The important part of this area is containing spits and low slope and delta. The result of this research can be used for infrastructure projects, port facilities, commercial and military activities.
