摘要

This report describes the use and operation of the tethered float breakwater system. This system is composed of a very large number of independently operating floats,each of which is quite small compared with a wave length. In a typical configuration,the floats are spherical,with high buoyancy,and are tethered just below the surface in a depth of water many times the float diameter. There is at least one diameter clear space between floats in all directions. The width parallel to the shore of this array or patch of floats is determined in the normal fashion by local topography and the requirements for width of wave shadow. The length of the array,or the number of rows of floats past which the wave field must advance,is determined by the desired level of wave energy attenuation. The general appearance of the breakwater is shown in this report. This breakwater system differs from other floating concepts in that the principal modification of the waves neither ensues from wave reflection nor from simple opposition to the wave particle motion. Rather the system is driven by pressure gradient forces into an opposition to the particle motion.
