Abstract
Many investigations on groundwater impact reveal that 10–50% of nutrient loading in coastal waters comes from the submarine ground water, particularly in the macro-tidal flat as in the west coast of Korea.In this study, we analyze the long-term observed data of groundwater and surface water quality, then material budeget has been investigated using a box model to quantify the contribution of groundwater effect to coastal water mass. The additional source of loading by submarine groundwater has been accounted for simulation of long-term prediction of coastal water quality by using the fully three-dimensional water quality model ROMS-ICM IKim and Lim, 2009; Kim et al., 2011). Long-term monitoring data set of coastal water quality indicates a possible signal of groundwater influence on the salinity reversal and the excess mass outbalancing the normal budget in Saemangeum tidal lake in Korea. In the present study, we analyze the observed data to examine the influence of submarine groundwater, and then a box model has been demonstrated to quantify the influx and efflux into/from. A three-dimensional numerical model has been applied to reproduce the process of groundwater dispersal and its effect on water quality of Saemangeum tidal lake. The water quality model (ROMS-ICM) consists of hydrodynamic model of ROMS and eutrophication model of CE-QUAL-ICM (Kim et al., 2011). The ROMS-ICM hasze the long-term observed data of groundwater and surface water quality, then material budeget has been investigated using a box model to quantify the contribution of groundwater effect to coastal water mass. The additional source of loading by submarine groundwater has been accounted for simulation of long-term prediction of coastal water quality by using the fully three-dimensional water quality model ROMS-ICM IKim and Lim, 2009; Kim et al., 2011).
