ABSTRACT

Agricultural water deficit and the effect of tide level occurred during 2014-2015 due to decrease in rainfall and runoff in downstream of Imjin River basin, including northern Gyeonggi-do. This paper analyzed the causes of the water deficit in Imjin River basin and proposed possible solutions. A trend analysis of precipitation and runoff revealed that runoff in the Imjin River has been decreased due to operation of dams in North Korea and the decrease in runoff from 2014 to 2015 was due largely to a reduction in precipitation. While there was no water deficit prior to the operation of the dams (an average low-flow of 46.84 ㎥/s), the average low-flow dropped to 27.99 ㎥/s after the dam operation which is less than water demand (29.88 ㎥/s). Based on the findings of the analyses, this paper proposed an alternative to meet the water demand by using Gunnam Dam and Hantangang Dam in the Imjin River basin during the dry season.
