Study on Volume of Wave Overtopping Gained Effectively by a 3-D Structure and Water Purification

对于海洋能源的利用，我们正在演示如何通过越浪来获得水头差，以及如何利用水头差来排放海水。设计的人工结构由两部分组成。一种是堤坝，用来激活越浪，有效地获得水头差。另一种是用来汇聚广泛分布的波能的墙。不仅在规则波上进行了一系列越浪试验，还在不规则波上进行了越浪试验。对有效利用结构获得的越浪体积进行了评价。此外，在已知单向电流所需体积的情况下，可以在此研究的基础上给出结构的最佳设计。

For the utilization of ocean energy, we are demonstrating how to gain the difference of water head by wave overtopping and how to discharge the sea water by using the head difference. The devised artificial structure is composed of two parts. One is dam to activate the wave overtopping and to gain effectively the head difference. The other is the walls to converge the widely distribute wave-energy. A series of experiments of wave overtopping were carried out not only on regular waves but also on irregular waves. The evaluation has been given for the volume of wave overtopping gained effectively using structure. In addition when the required volume is known to make a one-directional current, the best design of the structure can be given on the basis of this study.
