“…This force, being steady rather than oscillatory in nature, is very important in the design of offshore structures. Extensive calculations of mean drift forces on arrays of cylinders in channel can be found in Mclver and Linton [20]. A very simple and powerful approximate method for the determination of these second-order forces based II I II II II II II II I I II I I II I I II I I II I I II I I II p I I II I I I I on the plane-wave approximation is also given there.…”

The full linear problem of the scattering of water waves by an array of N bottom-mounted vertical circular cylinders situated in a channel of constant depth and width is solved using the method of multipoles. A simple formula is derived for the velocity potential in the vicinity of a cylinder, and in particular on the cylinder surfaces, which allows hydrodynamic quantities such as forces to be easily evaluated. The simplicity of the solution makes the evaluation of quantities of interest straightforward and extensive results are given. An approximate solution for the forces on the cylinders, based on the assumption that the wavelength of the incident wave is long compared with the cylinder radii, is also given, and this is compared with results from the 'exact' linear solution.

“…Such a formula was derived by Thomas [4] by considering the conservation of momentum flux down the channel. A more direct derivation can be obtained by applying Green's theorem to ¢ and O¢/Ox and this can be found in McIver and Linton [20]. The resulting identity is…”
