沖縄本島海岸の実態調査(第1報)
Survey of Northern Coast of Okinawa Island

In this paper, the author treats data of waves characteristics which were obtained by his survey of the Northern coast of Okinawa Isl. under normal weather conditions, and also he discusses the conditions of the coast in the view of Coastal Engineering. The following results were derived. 1) The wave heights on the sites were found somewhat higher than the normals for the wave periods, and as a result the wave steepness values of those waves were larger than the critical value of 0.025, prsented by J. W. Johnson. The fact maybe signs that on the sites, beach erosive actions of waves are progressive. 2) Presently beach defence works are built only partly along the coast. However, to prevent coast defect by the sea water and the disaster due to Typhoon it is necessary to add more defence works along the coast.
