This study analyzed the mechanism of groundwater discharge in coastal regions around Mt.Chokaisan using ALOS AVNIR-2 and PALSAR data. The following conclusions could be derived: (1) classification results using the ALOS AVNIR-2 and PALSAR data can be useful for detection of the groundwater discharge points and their analysis, (2) the differences in the timing of geological formation in the study area helps to understand the difference due to the amount and the spread of the submarine groundwater discharge, and (3) the relative salinity was one of the indicators that can detect the difference between seawater and groundwater (freshwater).
