COASTAL VULNERABILITY MAPPING OF KALIANDA COAST, SOUTH LAMPUNG, USING COASTAL VULNERABILITY INDEX (CVI) METHOD

Abstract

The coastal region is a strategic area that has enormous potential. Kalianda is one of the coastal areas in South Lampung which has great potential with the main activities are fisheries and marine tourism, but it is also vulnerable to physical effects. The purpose of this study was to assess the vulnerability of physical parameters and to analyze the level of Coastal Vulnerability Index (CVI) in Kalianda, South Lampung. The results showed that the vulnerability level of the Kalianda Coast based on the rate of shoreline change  and geomorphological parameters were at a very high level of vulnerability. Whereas based on the parameters of the mean significant wave height, the average tidal tides and beach slope, the Kalianda Coast was at a low level of vulnerability. Overall, the results of the analysis indicated that CVI value ranged from 3.10 to 9.94, which categorized as low and medium vulnerability levels. Distribution of Kalianda coastal vulnerability level along  3.30 km (11.29%) was at low vulnerability level and along 25.98 km (88.71%) was categorized as medium vulnerability level.
