| Abstract | This thesis is about by using the glass cross-section tank we did a series of study and experiment about submerged breakwater. According to different conditions such as different heights of submerged breakwater, different amplitude and period of the wave, and in the forward or reverse flow field, we found out the reflectivity, penetration rate, the loss rate, and the mechanism of the model. Taiwan is an island country with vast coastal and extensive offshore waters. Because of the extreme climate worldwide, the rising sea level, the Typhoons during summer and fall, and the huge waves, those problems brought to the crisis of the coastline retrogression. The numerous man-made facilities at the coast reduced the amount of sands from the upstream, and led to the erosion of the coastline as well. As a result, the waves became random and irregular due to the changes of the flow field. In order to find out the mechanism of the waves in reality and to protect the marine, we used the irregular waves to do the experiments. We focused on the effect of waves and flow field on the reflectivity, penetration rate, and the loss rate of the step-type submerged breakwater. |
