In the present study, we investigated the physical characteristics of ground water behaviors and sediment properties in intertidal flat of Nakdong River Estuary. Variations in level and temperature of the groundwater depended on tides. And increase of river discharge led to increase in groundwater level and decrease in ground salinity at a depth of several ten cm. Difference in permeability of the intertidal flat sediments due to content of fine fraction affect velocity of groundwtaer level decrease at low tide. Furthermore, enhancement of groundwater flow due to the increase in permeability leaded to decrease of fine fraction in the intertidal flat sediments.
