A technique for the generation of short crested waves in wave basins

This paper describes a technique for generating short crested waves in a laboratory using a multi element array of paddles. The control signal applied to each paddle in order to create a realistic sea is developed by using the technique of filtering white noise, building upon the preferred method previously used for wave generation in flumes. By using the side walls of the wave basin as reflectors a larger working area can be achieved than by using other techniques, and the need to calculate correlations between paddles in the array avoided.
