Abstract

In this study, sub-indicators, and thematic mid-indexes to evaluate the water use characteristics were selected through historical data analysis and factor analysis, and consisted of the subject approach framework. And the integrated index was developed to evaluate water use characteristics of the watershed. Using developed index, the water use characteristics were assessed for 812 standard basins with the exception for North Korea using data of 1990 to 2007 from the relevant agencies. A sensitivity analysis is conducted for this study to determine the proper way through various normalization and weighting methods. To increase the objectivity of developed index, the history of the damage indicators are excluded in the analysis. In addition, in order to ensure its reliability, results from index with and without consideration of the damage history were compared. Also, the index is also applied to real data for 2008 Gangwon region to verify its field applicability. Through the validation process this index confirmed the adequacy for the indicators selection and calculation method. The results of this study were analyzed based on the spatial and time vulnerability of the basin's water use, which can be applied to various parts such as priority decision-making for water business or policy, mitigations for the vulnerable components of the basin, and supporting measures to establishment by providing relevant information about it.

본 연구에서는 물이용특성을 평가할 수 있는 세부지표 및 주제별 중간지수를 과거자료 분석과 요인분석을 통하여 선정하고 주제접근방식의 구성체계로 구성하였다. 또한 이를 종합하여 유역의 물이용 특성을 평가할 수 있는 통합지수(이수취약성지수)를 개발하였다. 개발된 지수를 이용하여 1990년부터 2007년까지의 유관기관의 자료를 활용하여 북한을 제외한 812개의 표준유역에 대해 물이용 특성을 평가하였다. 지표산정에 있어 여러 표준화 및 가중치부여 방법 중 타당한 방법을 찾고자 민감도 분석을 실시하였으며 개발된 지표의 객관성을 높이고자 물이용 특성을 평가하기 위해 개발된 다른 지표와는 달리 피해이력을 세부지표에서 제외하였다. 또한 실증적인 지표 및 지수 개발과 신뢰성을 확보하기 위하여 피해이력 유무에 따른 결과 비교 분석과 2008년 강원지역에 현장 적용성 검토를 수행하였다. 이와 같은 지수의 검증 과정을 통하여 세부지표의 선정과 지수 산정 방법 및 산정식의 타당성을 확인하였다. 본 연구의 결과는 유역의 물이용 관련 취약성을 시 공간적으로 분석하고 이에 대한 관련 정보를 다양하게 제공함으로써 물이용 관련 사업이나 정책의 우선순위 결정, 취약부분에 대한 보완책 마련 등의 대책 및 수립을 지원하는 등 다양한 부분에 적용할 수 있을 것으로 판단된다.
