Development of Water Intake Works Utilizing Wind Wave for Increasing Seawater Exchange in Fishing Port

Abstract

Hydraulic experiments and some field surveys were conducted. Three types were developed by hydraulic experiments. They were found to have enough performance. But their performance was sensitive to tidal change because their principle was converting wave momentum near water surface into inflow. To maintain their performance well against large tidal range, the simple way was developed. Dissolved oxygen of generated inflow was found to be almost saturated every time because of mixing air and water at this facility. Generated inflow rate could be estimated by the developed numerical model and experimental formula.
