INVESTIGATION OF MEASURES AGAINST SAND DEPOSITION INSIDE OHTSU FISHING PORT USING BG MODEL

Abstract

 A large amount of sand was deposited in the wave shelter zone of Ohtsu fishing port, resulting in difficulty of the navigation at the port entrance. The BG model (a model for predicting three-dimensional model for beach changes based on Bagnold's concept) was applied to this problem. Measures against sand deposition inside the port were investigated and most appropriate measure was the extension of the jetty with a 100 m length at the tip of the west breakwater.
