Characteristics of Water Environments in Yong-Won Bay of Korea

Abstract

The characteristics of water environment of Yong-won Bay in Korea, where the coastal area has been largely reclaimed to construct Busan New Port, were investigated by means of field observation and numerical simulation. Low sea water exchange rate and stratification due to the residence of fresh water are found to be main causes of anoxic water in the western part of Yong-won Bay. Observed sediment which contains a lot of fresh organic matter, is possibly concerned with weak tidal current in the western part. Water-holding capability of organic sediment correlates with maximum current velocity. It seems possible to predict the sediment property by simulated current velocity.
