&nbsp;&nbsp;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<BR>&nbsp;&nbsp;1. In case of proposal 1, if an invaded wave is H&lt;SUB&gt;1/3&lt;/SUB&gt; = 8.46m, T&lt;SUB&gt;1/3&lt;/SUB&gt; = 13.0sec of an each wave direction the harbor calmness is as follows.<BR>&nbsp;&nbsp;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(H&lt;SUB&gt;1/3&lt;/SUB&gt;=2.0m) is invaded as usual.<BR>&nbsp;&nbsp;2. The calmness effect is more favorable by breakwater extension as proposal 2 &amp; 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.<BR>&nbsp;&nbsp;3. In case of proposal 4 the harbor calmness is considerable satisfactory at all direction and the wave height ratio of harbor under 0.1 when the high wave is invaded.<BR>&nbsp;&nbsp;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.
