A barrier island works as a buffer zone against wave and tidal forces, especially in river estuaries. To quantitatively analyze the buffer zone mechanism, understanding the wave, tide precipitation and groundwater-table by using long-term field observation is necessary. This study presents a coastal buffer zone mechanism in a barrier island (Jinudo) of the Nakdong river estuary in Busan, South Korea. For establishing a coastal buffer zone in a barrier island, we measured the groundwater at five observation points for 26 months from March 2012 and obtained wave and tidal data from a national o...
