study of physical vulnerability mapping of the coastal areas of north - east aceh

The coastal physical vulnerability study conducted in the north-east coast region of aceh, whichwas focused on the calculation of the physical vulnerability index based on the coastal vulnerabilityindex (cvi) method which was integrated with the geographic information system (gis) to determinethe most dominant contribution to coastal vulnerability. the index is calculated based on six variables:geomorphology, coastal erosion, slope, changes in sea level, wave height and tidal range. basically, theemphasis on methodological aspects is related to: (i) the use of gis techniques to construct, interpolate,filter, and sample data for shoreline networks, (ii) physical vulnerability calculations using the cvimethod approach, and (iii) values cvi is applied in vulnerability maps using the gis program byproviding cvi ratings to three levels, namely low, medium, and high. the results of this study indicatethat the coastal physical vulnerability of the north east aceh region is dominated by a moderate level ofvulnerability of 83.61% with 51 sub-districts, and then a low vulnerability of 9.84% with 6 sub-districts,and a high vulnerability of 6.56% with 4 sub-districts out of a total of 61 districts in 10 regencies / citieson the north-east coast of aceh. according to physical conditions, each variable has the same weight, sothat each variable has the same contribution to the vulnerability index of the north-east coastal region of
