Coastline changes are the most important and common processes in coastal zone. These changes were occurred in coastline of Hormozgan province in the Persian Gulf and Oman sea coasts in which terrestrial processes directly affect oceanic processes and vice versa. Coastline changes in Hormozgan province contain sedimentary and geomorphologic unit's transformation, subversion, erosion and substitutions to each other, sedimentation and occurrence of other ones. The main scopes of this project are determination of the rate of coastline changes in short period (27 years) and long period (quaternary) and determination of effective factors in these phenomena. This research is based on GIS investigations, field operations and laboratory Studies, Preparation of orthophotos for two periods of aerial photo (1967, 1993), GIS studies. Initial recognition of coastal features, investigation of maps exactness, sampling of fossils from paleoshorelines and borehole were done by field operations. Fossil samples were tested by 14C method at Jaber-Ebn-Hian laboratory in Iran. As the results of this research, 76 maps, 46 tables, 36 Pictures and then aproximatly 220 pages in the final report were presented. The main achievements are as follow: 1- Sedimentary unit's polygon maps 2- coastal sedimentary unit maps 3- erosion and sedimentation maps 4- paleoshorelines maps 6- superficial and vertical coastal changes rates and amounts 7- effective factors in coastline changes 8- coastal sedimentary sequences. Other achievements of this research were obtaining the best method for investigation of coastline changes in the Iran coastal zones, and late quaternary history of coastal Makran zone and coastal Zagros folded zone and areas of Hornozgan province, which need coastal protection.
