Research on major natural disasters and related technologies has become an important subject in geography and its application. The complexity analysis of the issue is possible in a system approach to theoretical and applied geography also in the integrity of physical and human geography.
Due to the Caspian Sea water-level fluctuation in coastal zone of Mahmoudabad which happens very quickly in decade scale, the observance of safety element will be possible in light of the integrated coastal zone management with determine of sea frontage. In this context, geography and especially geomorphology is a main basic in this kind of coastal management.
Detection of sea level fluctuations causing morphological changes in the earth surface and damage to facilities, clarifies the necessary of the present research to study the role of geomorphological indices in Mahmoudabad coast zone constructions. The Coastal Vulnerability Index (CVI) is one of the most commonly used and simple methods to assess coastal vulnerability to sea level rise, in particular due to erosion and/or inundation. The CVI provides a simple numerical basis for ranking sections of coastline in terms of their potential for change that can be used by managers to identify regions where risks may be relatively high. The CVI results can be displayed on maps to highlight regions where the factors that contribute to shoreline changes may have the greatest potential to contribute to changes to shoreline retreat.
