PLUNGING WAVE PRESSURES ON A SEMI-CYLINDRICAL TUBE

Abstract

Laboratory tests were made on a 6-inch diameter semi-cylindrical tube simulating a prototype concrete structure designed to be placed parallel to the coastline in the surf zone to intercept offshore transport of beach materials and thus preserving the beach The model beach was of fixed bed type with a slope of 1 to 15 The crest elevation of the tube was set at the still water level for most of the test runs and the sloping beach intersected a flat channel bottom at a depth of 20 75".
