Monitoring coastline changes in Amirabad Port by surveying coastline and sea level

Abstract

The process of erosion and desertification affects social communities, agricultural lands and natural resources in coastal areas. The rapid coastline changes would cause social and economic issues in the coastal areas. In this study, Miankaleh coasts and the eastern coastlines of Amirabad port have been surveyed due to existing benchmarks since June 2013 until December 2015 in order to analyze the coastline changes in Amirabad port. Then the surveyed lines were compared with sea levels at the time of surveying. The sea level data has been used (to calculate the beach slope) in order to monitor the sedimentation and erosion processes in the coastlines movements. The results of this comparison show that coastline changes are irregular and they may not follow the seal level changes. Therefore the coastline changes in these areas are influenced by erosion and sedimentation units. <strong> </strong>
