A study on the Varying Current with the Dredging Depth in Sachǒn-Bay

&nbsp;&nbsp;This study on the characteristics of the tidal current at the half closed bay selected Sach？n Bay located in the western Kyung-nam area as the object location of the study.<BR>&nbsp;&nbsp;Then, I analyzed the current with the varying dredging depth after the depth integral of the three Dimensional continuous equation and Navier-stokes equation.<BR>&nbsp;&nbsp;The study would get the follwing results, and the results could be used meamingfully as the analysis material about the dredging depth"s influnce on the surrounding ocean when developing the coastal port.<BR>&nbsp;&nbsp;1. When measuring the tidal current, there is a bit dispersion in the current direction of the observed object, but it is the wind effect at the bay. Considering that the calculated result is the shallow-water equation integranted in depth, the results can be concluded to in accored with my expectancy.<BR>&nbsp;&nbsp;2. In case of reclaiming and dredging, the flow velocity and direciton change constantly, compared with the present condition.<BR>&nbsp;&nbsp;3. At the wide bay dredge depth does not arrect the level of the ocean, but in case of inflow from the flood, the increase of the inflow of the river water affects the level of the ocean.<BR>&nbsp;&nbsp;4. As the dredge depth grows deep, the maximum flood tidal current and obb tidal current at the front coast of the reclaimed decreases a little. However, the wide area Pc-7 ～ Pc-9 doesn"t show any change.<BR>&nbsp;&nbsp;As we saw in the above result, feacturcs of the tidal current as the level of the ocean and the current velocity don"t change in the aspect of the ocean engineering, even if we increase the degree of the dredge depth up to 6m in Sach？n Bay.
