This study focuses on the use of computational model in the design of a breakwater structure, which aims to determine the propagation pattern of the long-term ocean waves, in order to understand their propagation from the deep waters, and to determine the distribution of their energy around a proposed breakwater construction site. The method used is computational simulation of the wave model using the 2D Boussinesq Wave (BW) Module of MIKE21 software. The simulation used an incoming wave of 4.6 m high, which corresponds to the 100 years return-period value. The results show that the existing breakwater layout can protect the harbour by reducing the incoming waveheight by up to 75%. At the proposed design condition, the propagation pattern of the incoming wave slightly differs from the existing condition. The presence of the slopes on both sides of the channel changes the wave direction outwards due to shoaling effects, and consequently, larger concentration of wave energy occurs at some parts of the proposed breakwater design. Results from the model are useful for the design of the new breakwater structures, which is designed according to the predicted wave energy distribution.

东爪哇图班工业区可持续沿海基础设施设计的波浪模型

本研究侧重于计算模型在防波堤结构设计中的应用,旨在确定长期海浪的传播模式,以了解其在深水区的传播,并确定其分布。拟建防波堤施工现场周围的能源。使用的方法是使用 MIKE21 软件的 2D Boussinesq Wave (BW) 模块对波浪模型进行计算模拟。模拟使用了 4.6 m 高的入射波,对应于 100 年的回归期值。结果表明,现有的防波堤布局可以通过将来波高度降低多达 75% 来保护港口。在建议的设计条件下,入射波的传播模式与现有条件略有不同。由于浅滩效应,通道两侧斜坡的存在使波浪的方向向外改变,因此,在拟议的防波堤设计的某些部分会出现较大的波浪能集中。该模型的结果可用于设计新的防波堤结构,该结构是根据预测的波浪能量分布进行设计的。
