Abstract

In order to evaluate the effects of v ariations of the fresh-saltwater interface on SGD (Submarine Groundwater Discharge), continuous measurements of SGD rates, conductivity and temperature of SGD by automated seepage meters and CT sensors were conducted in the study area. As the results, different variations were found in SGD rates, temperature and conductivity of SGD at sea side and land side of the fresh-saltwater interface. SGD was simulated by groundwater discharge model based on the function of the distance from the coast. Variations of calculated SGD agreed with variations of observed SGD at land side of the interface, however not offshore of the fresh-saltwater interface.
