An Experimental Field Study Using a Flexible
High-Strength Net Breakwater for Shore Protection


Shorelines are subjected to severe erosion because of the action of perennial waves. Although traditional rigid structures have historically been constructed as coastline protection devices, they do not always work effectively, and certain coastal areas such as Shuang-Chun beach in Tainan, Taiwan, continue to experience serious erosion due to damaged and ineffective structures. The necessity of shore protection has been recognized in recent years, and alternative solutions are being sought. In this paper, we present a high-strength-net device that acts as a flexible breakwater to reduce wave energy, induce sediment deposition, and offer a more economic and innovative method for coastline protection. The device is composed of concrete posts, high-strength nets, and triangular gabions filled with stones and covered with recycled vehicle tires. Three high-strength-net breakwaters have been installed at Shuang-Chun beach since 2009 as an experimental field study to investigate both the effect of sediment deposition and the stability of the proposed breakwaters. Results show that these devices have the strength and stability to withstand the impact of severe wave action, and that they act effectively as sediment retainers, thereby preventing coastal erosion. © 2015, National Taiwan Ocean University.

Derosion Lattice Performance and Optimization in Solving an End Effect Assessed by CFD: A Case Study in Thailand’s Beach


Thailand’s beach had a severe coastal erosion problem at the end of rock dams called the “end effect”. One of the innovative solutions to solve this problem is to use the derosion lattice (DL). However, since the DL performance depends on installing conditions such as angle of attack, placement position, terrain, and climate, computational fluid dynamics (CFD) was applied to assess the end effect’s occurrence and optimize the performance of DL’s installation. Based on Khao Rup Chang’s condition, a suffered beach in Thailand was used as a case study, and a free surface flow simulation was performed in the transient state using ANSYS Fluent, a CFD software, which revealed water waves flow through the beach with and without the DL installation cases. Furthermore, the CFD-assessed results indicated that the angle of attack and placement position affected the DL performance as expected. In optimization, the 15° angle of attack with the DL placement adjacent to the rock dam was the proper condition. After being applied at the actual site, the DL can help reduce erosion, increase sedimentation, and solve the end effect with excellent performance.
