영문 초록

This paper has examined about the effect of the flow and pollutant dispersion by the discharge control at the estuary weir in Mokpo Bay, using a field survey data and results of numerical experiment. For this paper, using the numerical model is constructed two-dimensional simple layer model, and its analysed the implicit finite difference method(ADI). The results of the paper is clarified, 1) The flow pattern of the numerical experiments is similar to the others. 2) When the flow is the maximum discharge, the variation of velocity has a 2 ㎝/sec rise at the front of th estuary on spring tide. 3) It’s showed that the tide level is 2㎝ rise at T1, T2, T3 of 8㎞ around from the entrance. 4) The variation of COD is distributed 1.5㎎/ℓ~1.0㎎/ℓ in 1㎞ from the estuary entrance, it is showed 1.0 ~0.5㎎/ℓ at Kohado around.
