Abstract

This study was carried out for verification of efficiency of seawater exchange breakwater which was installed in joomoongin harbor for the first time in our country. The joomoongin harbor, where seawater exchange breakwater has been constructed, shows typical for fishery and tourist port city specifics of greatest pollutants discharge volume in spring and summer, when tourist inflow and fishery activity is most vigorous. On the East Sea seawater flux through seawater exchange breakwater for the smallest waves (up to 0.5 m) was found out to be $1,526-3,052m^3/day$. After construction of seawater exchange breakwater, Zone 1 and Zone 2 of stagnant water inside the port were found to be a lot improved. Zone 3, adjacent to outport area, was found to be lower comparing with Zone 1 and Zone 2. The results of statistical analysis show that comparing with water quality improvement effect before and after seawater exchange, water quality after installation of seawater exchange breakwater became much better, primarily because of physical change around the harbour.
