ANALYSES OF BOUNDARY-VALUE PROBLEMS BY MEANS OF GREEN'S IDENTITY FORMULA FOR TWO-DIMENSIONAL WAVES OF FINITE WATER DEPTH

A method of numerical analysis which is simplified by means of Green's identity formula is proposed for the analyses of two-dimensional boundary-value problems of small amplitude waves in finite water depth. As examples of application, this paper presents the formulation and numerical results for wave transformation by permeable breakwater, seawall and submerged breakwater of arbitrary cross sections, by linearizing the fluid resistance in porous material so as to be proportional to the fluid velocities. The problems for those structures with vertical faces were solved by a method of continuation of velocity potentials.
