Abstract

Recently in Japan, there are some projects of constructing very large float- ing structures (VLFS) such as ocean airports. The exchange ratio of sea water can be an important index in evaluating influences of VLFS on ma- rine environment. The main purpose of the present study is to investigate the influences of large-scale ocean structures on exchange of sea water by means of numerical experiments. At first, the results of numerical calcula- tions were compared with field observation and hydraulic model experiments in order to validate the numerical model. The exchange ratio obtained by the calculation agreed well with the observation, and the calculation could also reproduce the influences of breakwater appeared in
