Wave Forces Acting on a Submerged Semi-circular Jetty

According to the results of design and test of a semi-circular jetty at estuary of Yangtze river, it has been shown that the cross section of a submerged jetty structure will be unsafe when the general empirical wave force formula for semi-circular breakwater is used in design. Therefore, a new calculation method for the wave forces acting on a submerged semi-circular structure is given in the present paper.
