A METHOD TO PREDICT DISTRIBUTION OF MARINE DEBRIS DEPOSITED ON A BEACH

Abstract

 In the previous study, a method of observing both beach topography and the distribution of marine debris deposited on a coast was developed based on field observations before and after a storm at the Onuki coast south of Oharai Port. In this study, field observation of the deposition of marine debris was carried out on the Shichiri-Mihama coast in Mie Prefecture. A method to predict the distribution of marine debris deposited on a coast was newly developed, taking the effect of wave run-up to the deposition of marine debris on the beach into account. The observed and predicted distributions of marine debris were considerably in good agreement.
