| Abstract | ||||
| The seabed changes around the pile breakwater were examined experimentally. The breakwater consists of vertical double rows of closely spaced circular piles. This is for determining the additional embedded length of the pile in the soil due to scour caused by the wave action. The seabed hydrography was recorded and the maximum scour and maximum deposition were determined for different wave conditions. Intermediate and shallow water waves were applied. It is concluded that the seabed scour reaches the maximum value when the dimensionless wave number ranged between 0.5 and 1.0 under the experiment conditions. The relative maximum scour depths around the seaward and shoreward rows arc 0.29 and 0.20 respectively. Also, the breakwater is more effective for reducing the sediment transports normal to the shore-line when the dimensionless wave number is greater than or equal 1.0. | ||||
