Coastlines are one of the most important phenomenon in the surface of the earth, with a dynamic nature. Monitoring of coastal area is an important parameter for sustainable development and environmental protection. Coastal area monitoring requires the extraction of coastlines at different times. Today, data collection is considered as the most efficient source of information for the study of coastal landforms, tidal levels, coastline variation, and depth of the water. The purpose of this study was to estimate the changes in the coastline of the Miankaleh gulf area that is located on the southeast coast of the Caspian Sea, using remote sensing techniques. This study examines the qualitative and quantitative interpretation of coastline changes in the 44 years period. The main research tool is the MSS, TM, RVB, OLI and ETM+ Land Rover satellite images. The results of net changes show that, a deramatic rise was occurred in the gulf of Miankaleh. But after year of 1977, this trend was reversed. The coastal variation line with estimation of mean weighted suggests that, the study area was appears to be moderately antecedent, in the period of 44-year.
