Mapping of Coastal Vulnerability using the Coastal Vulnerability Index and Geographic Information System

Frida Aprilia Loinenak, Agus Hartoko, Max Rudolf Muskananfola

 

Abstract: The mapping of coastal vulnerability using the Coastal
Vulnerability Index (CVI) and the Geographic Information System (GIS) at Doreri Bay, Manokwari
Regency, West Papua Province was carried out from September 2013 to March 2014. The aims of this study are to analyze
and map the coastal vulnerability of Doreri Bay. The study was conducted using a combination of the CVI and GIS
methods to assess the geological and physical parameters of the coastal region.
The geological parameters consisted of geomorphology, coastline changes
(accretion/erosion), the coastline slope, and physical processes. The physical
parameters consisted of the relative changes in the sea surface height, the
average wave height, and the average tidal height. The results of this research
show that the CVI values were within the range of 6.7–43.3, and there were five
class categories of coastal vulnerability: (1) very low vulnerability with an
area of 6,635.4 Ha or 47.8%, (2) low vulnerability with an area of 2,654.1
Ha or 19.1%, (3)
medium vulnerability with an area of 1,692.8 Ha or 12.2%, (4) high vulnerability with
an area of 992.7
Ha or 7.2%, and
(5) very high vulnerability with an area of 1,904.2 Ha or 13.7%.



Keywords: Class ranks; Coastal vulnerability index; Doreri Bay; Geographic information systems; Spatial analysis
