<Li> incompressible, inviscid water and wind </Li> <Li> slope of the displacement of the water surface is small </Li> <P> Generally these wave formation mechanisms occur together on the water surface and eventually produce fully developed waves . </P> <P> For example, if we assume a flat sea surface (Beaufort state 0), and a sudden wind flow blows steadily across the sea surface, the physical wave generation process follows the sequence: </P>

Which value is the best estimate for the depth of the water in the open ocean
