چکیده
Background and Objectives: Coastal physical vulnerability studies were first conducted by Gornitz in 1991 on the west coast of Atlantic Ocean, have since been studied extensively other parts world. In this article, determining severity Sefidrood delta coast, identifying coastal landforms how they deform over time are main objectives research. Methods: By using results field monitoring, interpreting remote sensing digital changes coastlines GIS environment, studying effective criteria coasts such as: slope, type sediments, landforms, rates line changes, calculated. Findings: The show that degree varies different regions. Areas leading to western eastern estuaries Sefidrud River highest with increasing distance from estuary east, gradually decreases. Erosive area adjacent formed as erosive terraces sand spits extremities delta. Conclusion: is affected forces Caspian Sea, high volume sedimentation sandy materials produced under influence currents has ability create sedimentary area. Achieving a map White Delta provides conditions for making right decisions integrated zone management, method can be used areas.
