An effective and efficient prediction of hydrodynamic performance of curtainwall-pile breakwaters .

This paper describes hydrodynamic characteristics of a curtainwall-pile breakwater (CPB), the upper part of which is a vertical wall, and the lower part consisting of an array of vertical piles. For regular waves, using eigenfunction expansion method, a numerical method have been developed that can compute wave transmission, reflection, and other hydrodynamic characteristics of the breakwater. To achieve effective prediction of hydrodynamic performance of curtainwall-pile breakwaters and overcome problem of underestimation of energy loss evanescent wave are considered. Then optimum number of necessary evanescent waves for an effective and efficient prediction is discussed for various hydrodynamicquantities of interest
