Abstract

The curvature distribution of the wind-disturbed water surface in a laboratory tank is observed from different angles with an optical instrument. The distribution is generally skewed with greater radius of curvature at steeper viewing angles from the normal to the mean water surface. As the wind velocity increases, the average radius of curvature decreases: rapidly at low wind velocities when waves are effectively excited by wind, and gradually at high wind velocities when waves approach saturated state.
