Comparative Radial Analysis of Philippines’ Local Flood Vulnerability Index

국문 초록 (Abstract)

오늘날 인명피해, 경제손실, 가축피해 등을 야기하는 홍수는 국제적 관심사이며, 피해를 저감시키기 위해 꾸준히 노력하고 있다. 또한, 필리핀에서도 홍수는 주요 관심사이며, 홍수취약성 분석을 위해 홍수취약도지수(FVI)분석 방법을 사용하여 취약성분석을 수행하고 있다. 그러나 광범위한 지역에 대해 FVI 분석을 수행하기 때문에 홍수취약지역이 정밀하게 분석되지 않고 있다. 본 연구에서는 소규모 지역에 FVI 방법을 적용하기 위하여 필리핀 Albay지방 다섯 개 지역(1개 도시와 4개 지방지치구)에 대해 취약성을 분석하고, 비교하였다. FVI분석의 요소와 지표를 평가하기 위해 전문가 대상의 설문을 이용한 방법인 AHP 방법을 사용하였다. 과거 10년(2006~2015) 동안의 홍수피해 자료를 수집하여 처음 5개년 자료는 보정, 나머지 5개년 자료는 검증을 위해 사용하였으며, 이를 통해 0에서 1의 범위로 홍수취약성을 표준화하여 ‘매우 낮음’, ‘낮음’, ‘보통’, ‘높음’, ‘매우 높음’으로 구분하였다.
각 구성요소(사회적, 경제적, 환경적, 물리적)에 대한 분석결과, 5개 지역 모두 환경적 요소 및 물리적 요소에 대한 취약성은 ‘매우 높음’으로 평가되었으며, 사회적 요소 및 경제적 요소에 대한 취약성은 ‘보통’에서 ‘높음’으로 평가되었다. 종합적인 FVI 분석결과 Manito 지역의 취약성이 0.632로 홍수에 가장 취약한 것으로 평가 되었으며, Guinobatan, Bacacay, Camalig, Legazpi 지역에서 각각 0.632, 0.576, 0.521, 0.509로 분석되었다. 위의 결과를 통해 소규모 지역에 FVI평가를 진행함으로서 구체적인 홍수취약성 분석이 가능한 것으로 확인되었다.

Flood has been a primary concern and one of the global issues today, because it has been knocking down lives, economy, live stocks which people has been striving to protect. In the Philippines, flood is also a big issue and although there is an existing flood vulnerability index (FVI) assessment, vulnerable areas are not accurately identified because it is done on a larger scale basis. In this research an FVI under a smaller scale was used to assess the vulnerability of five areas (one city and four municipalities) in the province of Albay, Philippines. A comparative analysis was also performed to identify which among these five areas are more vulnerable to flooding. Analytical Hierarchy Process (AHP) was used to weigh the indicators and components through the expert decision from surveys made by different professionals. A 10-year data from 2006 to 2015 was collected wherein the first 5 years was used for calibration and the succeeding years was for verification. The outcome is standardized with values ranging from 0 to 1 (extremely low, low, moderate, high and extremely high).
Finally, assessment of each components (social, economic, environmental and physical) showed that all five areas are identified to be extremely high vulnerable for both environmental and physical components. While for the social and economic component, the value ranges from moderate to high vulnerability. Manito has the highest overall FVI with a value of 0.655, followed by Guinobatan, Bacacay, Camalig and lastly, Legazpi with values of 0.632, 0.576, 0.521 and 0.509, respectively. Therefore, application of FVI assessment to smaller scale areas provides specific results in identifying the areas which are vulnerable to flooding.
