INTERACTION OF A PLANE SOLITARY WAVE WITH A RIGID VERTICAL CYLINDER

The diffraction of a plane solitary wave by a rigid vertical circular cylinder and the resulting wave loading on the cylindrical surface are investigated. Based on the higher-order Boussinesq equations, the sec ond order approximation Sor the solitary wave equation is derived. The analytical solution is obtained by means of a Fourier transformation technique. Investigation of the wave action on the vertical cylinder i s of importance in harbor - and offshore engineering and, in combinati on with the wave imaging technique, in the design of ''cylindrical'' a rch-dams with radial extending plane walls.
