     studies carried out in the southern coast caspian sea reveal that some pairs of coastal zone has been severely and increasingly impacted by sea level rise in the last 25 years. therefore this work can be a start point that supports the coastal zone management program of the southern coast of caspian sea through the identification, assessment and classification of the coastal zone. this is achieved by using a geographic information system in order to create a so-called composite vulnerability index (cvi); the cvi includes 5 variables describing two dimensions (natural and human-induced dimensions). by means of gis (arc map 9) these variables are classified, weighted and combined to yield a single vulnerability indicator or cvi. the vulnerability index describes 4 classes, from low to very high vulnerability. the key results of this study are then presented in the three maps, showing the natural vulnerability, human-induced vulnerability and the total (=composite) vulnerability for gilan district. this index now provides a reliable, easily applicable tool for the measurement and description of the coastal susceptibility to sea level rise.
