Through a study as hydraulic model test that applied a calmness test to the coast of Hongdo harbor as an optimal surface arrangement we could reach the following conclusion
1. In case of proposal 1, if an invaded wave is H₁/₃=8.46m, T₁/₃=13.0sec of an each wave direction the harbor calmness is as follows.
The wave height ratio is about 0.6 at the entrance of a harbor 0.2∼0.3 anchor area in general and the value under 0.1 when the wave(H₁/₃=2.0m) is invaded as usual.
2. The calmness effect is more favorable by breakwater extension as proposal 2 & 3, but if the high wave is assaulted the wave height ratio of anchor area is 0.1∼0.2 owing to the diffraction wave at a SSE, SE direction.
3. In case of proposal 4 the harbor calmness is considerable satisfactory at ail direction and the wave height ratio of harbor under 0.1 when the high wave is invaded.
Thereafter, a study that analyze and compare with the hydraulic model test by numerical analysis about the problem of harbor calmness that a short period wave has superiority will be continued
