Abstract

Drought has strong local characteristics, an objective definition or standard that can define the progress or severity of drought is needed and to date, many drought-related studies are being conducted around the world. In this study, Standardized Precipitation Index (SPI), which is a representative meteorological drought index, was calculated, and the drought risk index (DRI) that can consider actual drought was applied to the target area, Uiryeong-gun, by applying the drought vulnerability index (DVI) and the drought hazard index (DHI). A method for practical drought evaluation that can establish a water supply system is presented in this study.

가뭄은 지역적 특성이 강하게 나타나므로 가뭄이 진행하는 상태나 심한 정도를 정의할 수 있는 객관적인 정의나 기준이 필요하다. 이를 위해 가뭄지수(drought index)란 개념은 증발산량을 정량적으로 제시하면서 시작되었으며, 현재까지 전 세계적으로 많은 가뭄 관련 연구가 수행되고 있다. 본 연구에서는 대표적인 기상학적 가뭄지수인 표준 강수 지수(SPI)를 산정하였고, 실질적인 가뭄을 고려할 수 있는 가뭄 위험 지수(DRI)를 가뭄 취약성 지수(DVI)와 가뭄 위험요소 지수(DHI)를 대상지역인 의령군에 적용하여 안정적인 용수공급 체계를 마련할 수 있는 실제적인 가뭄의 평가에 대한 방법을 제시하였다.
