부산주변해역의 해수유동 및 수질환경 특성에 관한 연구

Abstract

It is very important to quantitatively assess the movement of sea water before or after constructing shore structures such as breackwaters considering marine environment. This assesment 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 the port of Pusan. The computational models adopting ADI Method(Alternating Direction Implicit Method) was already verified from the previous studies, was used here.

And the numerical calculations of pollutant transport in the sea water area were carried out to asses the effect of river inflow.

To achieve this purpose, 4 cases were set as follows

1. case 0 : the present condition of river inflow into the sea area,

2. case 1 : 70% of the present condition,

3. case 2 : 50% of the present condition,

4. case 3 : be equipped with sewage treatment works(inflow concentration

20 mg/l of COD)

In each case, we could get the result of quantitative analysis. If the sewage treatment works for river discharge is equipped, the sea quality of the area will be more than the present condition.

As a result of this study, much of tidal data around the area could be gained to use the future study and to give the basic materials for the new city plans including the sea area around the city.
