증발산량과 강수량을 변수로 하는 SPEI (Standardized Precipitation Evapotranspiration Index)는 보편적으로 기상학적 가뭄심도를 정량화하는데 이용되고 있다. 또한 RDI (Reconnaissance Drought Index)는 가뭄의 피해를 받고 있는 지역에 활용도가 높은 가뭄지수이지만 이를 이용한 국내 적용사례는 부족한 실정이다. 따라서 본 연구에서는 Thornthwatie, Hargreaves, Blaney-Criddle 증발산량 산정 방법을 이용하여 증발산량과 강수량을 변수로 하는 SPEI와 RDI를 비교하였다. 1992년부터 2015년까지 한강 유역에 대한 가뭄 정량화 및 특징 비교를 위해 기상청 관할 16개 지점의 기상자료를 이용하였다. 연구결과, 한강유역의 경우 최근 들어 급격히 극한 가뭄이 발생하고 있는 지점들이 증가하였다. 두 가뭄지수 사이에 상관정도는 비교적 높았으나 가뭄의 심도 및 극한가뭄의 발생 연도 사이에는 일부 차이를 보였다. 따라서 가뭄 심도와 발생 시기의 정량화를 위해 RDI 또한 활용이 필요함을 확인하였다.
