  • Abstract In this thesis,I discuss the wave pass on submerged bweakwater,and theheight of submerged breakwater,different slope of submerged breakwater
    with breaking wave relations.I do experiment to find the regular between breaking wave and the design of submerged breakwater.I use different submerged breakwater,there are two slope.There are 1/2 and 1/5.The height of submerged breakwater is 45 cm,the wide of submerged breakwater is 75 cm.the water deep is from 50cm to 90 cm,Wave cyclical is from 1.2 sec to 2.7 sec,I use H L to choose wave height,and save the data of incident wave.and then I analysis the data to get t K and energy.I also memorize the site of breaking wave and breaking type. From the experiment ,we know that wave do not be broken, be broken, and the regular of breaking wave and breaking type ,so we can use the regular to design the height of submerged breakwater, the slope of submerged breakwater. So we can use the least costs to protect the seacoast. When we know local wave condition, we can design the height of submerged breakwater to break wave that is dangerous for seacoast ,or we want to break wave when the wave height at 1 m or 2 m or others design the height of submerged breakwater. When σ^2h/g is between 0.3 and 2.5,we can find that when R/H0’ is smaller than 1,the wave will break。When wave break bysubmerged breakwater ,we can find the slope of 1/5 is better than the slope of 1/2 to reduce the wave.Both slope of 1/2 and slope of 1/5 are effective to reduce wave energy at Hi/R=2.
