“…Seawater nearly simultaneously enters Gamak Bay through the east and south channels during the flood tide and recedes through the opposite side during the ebb tide (Lee and Park, 2004). In Fig.5, the Eulerian residual currents for each season with and without wind forcing are shown.…”

The flow and seawater exchange rates have been predicted using a two-dimensional numerical model and a Lagrangian method for a semi-enclosed shallow bay where reclaiming and dredging works are scheduled. The wind effect on the flow and material transport has been emphasized, and a thirty-year mean value of wind has been considered in the numerical simulation. As a whole, even after the reclaiming and dredging arc conducted, the flow pattern looks similar to the original state. However, velocity variations up to 20% to 100% appear in the vicinity of the construction area. In the case of summer wind forcing, the seawater exchange rate increases from 71.6% to 82.9% after the reclaiming and dredging, as indicated by a particle-tracking method. On the contrary, in the case of winter wind forcing, the seawater exchange rate appears to be 97.2% under natural conditions but decreases slightly to 93.2% after the reclaiming and dredging. Thus, the wind forcing plays an important role in controlling the seawater exchange rates. The seawater exchange rate is further improved by 15% if the dredging is simultaneously carried out with the reclaiming. This suggests that the dredging can be an effective means to mitigate the variation of flow.

In order to understand temperature and salinity variations, and the characteristics of the seawater exchange through two channels of Gamak Bay, we conducted measurements of water temperature, salinity and current for fifteen days in the summer and winter. Based on the observational data, the current seemed to have a close relation with wind. In addition, a correlation analysis result proved that water temperature is likely to be more influenced by air temperature rather than tide. Moreover, water temperatures at the south channel varied more sensitively with the season rather than at the east channel because of its shallow depth. Seawater exchange rates were estimated to be 0.5~29.9% (mean: 11.6%) at the east channel but 1.3~62.6% (mean: 18.6%) at the south channel in summer. On the contrary, they were estimated to be 0.3~28.5% (mean: 8.9%) at the east channel but 0.1~97.9% (mean: 31.2%) at the south channel in winter. Thus, the rates of seawater exchange in Gamak Bay turned out that the south mouth is approximately three times higher than the east mouth, and it also suggested that seasonal winds affect the rates of seawater exchange in Gamak Bay.
