Abstract : The wind-disturbed water surface consists of waves of various lengths moving at various speeds. There is increasing interest in determining the statistical properties of the microstructure of such a surface. Measurement of the curvature distributions of wind waves viewed from different angles is helpful for understanding nonlinear interaction between ripples and carrier waves, and is important for interpreting reflection and back-scattering from the sea surface. In the present study, both slope and curvature distributions of the disturbed water surface under various wind conditions in a laboratory tank are simultaneously and systematically measured from all inclinations to the mean water surface, but in a plane containing the wind direction and perpendicular to the water surface.
