파랑에너지를 이용한 항내 해수순환증진에 대한 연구

Abstract

In the present paper, a method which enhances the circulation of harbor waters by using waveenergy was investigated. The overflow leve was selected as a coastal structure helping the harbor circulation,and was aplied to Jeju-outer-port site so as to estimate its effectivenes quantitatively in probabilistic point ofview. It was asumed that sea water influx rate through the overflow leve into the harbor depended upon waveheight and tidal level and a functional relationship among them was calculated using the results of hydraulicexperiment. The probability distribution of water influx could be obtained from hindcasted wave data andmeasured tidal elevations at Jeju harbor. The Gamma distribution was appeared to best fit the estimated influxdistribution, and the optimal location of the levee was discused. Finally, water quality purification effect wasinvestigated by computing the contaminant material dispersion acording to whether the levee was or not.
