INTRODUCTION The latest 2014-2015 drought in Korea caused water scarcity of multipurpose dams that supply living and industrial water and led to difficulty with water management. This drought was so severe that it was recorded as an unprecedented event. Drought affects more people than other natural disasters and results in an enormous social, economic and environmental cost ([1]). Sheffield et al.
