Investigation the mechanism of changes in the coastal landscapes of southeastern Iran based on geomorphological studies

The southeast coasts of Iran as a part of the coasts of Makran are always changing. Since the southeastern coast of Iran is one of the most important strategic regions of the country and even the Middle East, it is obvious that the information related to geomorphology and other earth sciences can be an important factor both in organizing planning plans and policies and in evaluating private demands. The most important goal of the research is to introduce the factors affecting the change of landscape and coastal geomorphology phenomena and the state of erosion and sedimentation along these coasts. Library and documentary studies, field operations, laboratory studies, combining findings and conclusions have been the main methods of conducting research. In this research, the principles of catastrophism, uniform materialism, gradualism, and Davis's theory have been used. The coastal area of Makran is under the influence of three tectonic, erosion and sedimentation activities and human activities (industrial, fishing and construction) are not effective. Two general models include the dominance of erosive and tectonic processes over sedimentation processes, causing the formation of landscapes such as erosion columns, sea stacks, sea arches, sea caves, headlands, Islands and raised beaches (Cliff) are found in the coastal areas of Pasabandar, Beris, Lipar, Tis, and Konarak, and the other is the dominance of sedimentation processes over other activities, which are landscapes such as Spit, Bar, Tombolo, Lagoon, Delta, Tidal Flat, Bay Barrier, Islands and Mud Flat in the coastal areas of Ramin, Chabahar Bay and Govatr.
