- It is very important to quantitatively assess the movement of sea water before or after constructing sea dike. The assessment is possible through the use of simulation models designed to predict water movement in a certain area.
In this study, the numerical computations were carried out to predict the sea water movement and quality around Seamangeum developing area. The computational models adopting ADI Method(Altering Direction Implicit Method) that was already verified from the previous studies, was used here.
In Seamangeum developing area, the major water masses are offshore water, Keum River diluted water, Mankyung River Diluted water and Gomso bay diluted water. The diluted waters are characterized by lower salinity in all seasons, and higher temperature from the end of Feb. to summer and lower temperature in November.
Tidal water movements various. Slack waters occur at high and low tides, and maximum current speeds at 2-3 hrs after high and low tides. And the seasonal variations of water quality are more dominant than spatial variations, while the salinity inside of the Dike is usually lower than the outside salinity.
To test the model performance of simulating the pollutant transport, the field data of the other research was used in comparing the result of modelling computation. The model results showed a relatively good agreement with observations.
