Abstract : A linear array of wave sensors was used in a laboratory wave basin to measure the direction of waves approaching from one and two directions. The basin is 18 meters x 15 meters x 1 meter. Two plunger type wave generators were used; one was on the 18-meter wall, the other on the 15-meter wall, so that the wave trains were normal to each other. The linear array was placed so that waves would approach at angles of 50 degrees from one generator and 40 degrees from the other. Three 1-millimeter minidigital staffs were used to measure waves. The staffs were connected by cable to a computer. Results are presented graphically and in tables. It appears that when used with full knowledge of its limitations, the linear array supplies the simplicity and accuracy needed for many nearshore wave array applications. (Author)
