Abstract
Korea has a terrain vulnerable to drought due to the concentration of precipitation in summer and the large amount of groundwater discharge. Quantified drought indices are used to determine these droughts. Among these, drought index is mainly used for analysis of precipitation, and recently, researches have been conducted to monitor drought using satellite images. In this study, we used the KOMPSAT-2/3 image to calculate the water surface area and compare with the drought index in order to monitor the drought in the Upper Soyang River. As a result, it was confirmed that the tendency of the water surface area change and the trend of the drought index were similar in the satellite images. Future research could be used as a basis for judging drought.
