Abstract

Using monthly rainfalls, this study investigated outliers of annual and/or seasonal rainfall for quantitative assessment of historical droughts in Korea. Based on the analysis of annual rainfall, Icheon, Geochang, Jeongeup, Suncheon and Jangheung gaging stations were selected to represent the major river basins, because they had most frequent dry years. The overall results indicated that the years of 1988 and 1994 were the worst dry years. Although the 2001 drought was not severe, it resulted in typical agricultural drought damage mainly in Seomjin and Yeongsan river basin due to the lack of agricultural water. On the other hand, the droughts of 1981-1982 and 1994-1995 were long term nation wide droughts that lasted more than two years resulting in extensive drought damages to parts of the country.

본 연구에서는 우리나라에서 발생했던 과거 가뭄사상을 정량적으로 평가하기 위해 우리나라의 59개 기상관측소의 월강수량 자료를 이용하여 연강수량 및 계절별(봄철) 강수량에 대한 이상치($-1{\sigma}$)를 분석하였다. 연강수량을 통해 이상치 발생 빈도를 구하여 그 중 가장 유역별로 과우해($-1{\sigma}$) 발생빈도가 높은 이천, 거창, 정읍, 순천, 장흥 관측소를 선정하여 이상치를 분석한 결과 1988, 1994년이 동일하게 심한 과우해로 나타났다. 전체 이상치 기간 분석결과와 봄철 이상치 분석결과를 통해 2001년 가뭄은 심한 과우해로 분류되지는 않았지만 주로 섬진강 및 영산강 유역을 중심으로 심한 봄 가뭄이 발생하였으며, 농업용수 부족으로 인한 농작물 피해를 발생시킨 대표적인 농업적 가뭄연도로 분석되었다. 반면에 1981-1982년 및 1994-1995년과 같이 2년 이상 지속된 전국적 장기가뭄은 국가적으로 큰 가뭄피해를 야기하였다.
