Field measurement was carried out for the breakwater caisson newly built in Bose fishing port with the purpose of confirming the capability of water exchange resulting from incident waves. Because Bose is situated in inland-sea area, incident waves are as small as 0.15m in height, which are generated mainly by running ships. In spite of small waves net quantity of conductedw ater excludingw ater-currenct ontributionis obtaineda s mucha s 5m3p er one hour for lm caisson. Predicted values of conducted water based on the model experiment are roughly same as those of field measurement.
