“…52 Over the sloping beds, the Goda and Suzuki’s method has been applied by several investigators. 53–57 Most of them utilized different simplifications to consider wave shoaling and phase shift effects. The water depths studied herein included the deep to medium water depth conditions, thereby this method applies on our measurements.…”

A submerged flexible mound breakwater can be employed for wave control in shallow water as an advanced alternative to the conventional rigid submerged designs. This study presents a flexible breakwater with an innovative geometry based on model experimentation. Experimental studies were performed to compare the wave energy dissipation by the flexible mound and rigid structures, over a range of test conditions, for example, three different diameters of structure, three water depths, and different regular wave heights for three different beach slopes. Results indicate that the present submerged flexible mound breakwater is stable, being appropriate for most operational sea conditions. Large amplitude waves can induce significant motions of the structure; therefore, the interaction between radiating and scattering waves is highly contributing to the wave energy dissipation. The wave energy dissipation at breaking zone of the present submerged flexible mound breakwater is significantly greater than that of the other types of flexible and rigid formerly investigated structures.

“…Wang et al [17] proposed a three-point method for estimating wave reflection to account for monochromatic oblique incident waves propagating over a sloping beach. The submerged obstacles with different shapes, solids and porous solids have been studied extensively in order to determine the reflection and transmission of ocean waves, and representative works can be found elsewhere (see [18][19][20][21]). …”

“…Consequently, these methods are very inconvenient to carry out in the field, and the requirements on the bottom state of the material are too high in terms of the shape of the free bottom surface. In this paper, from industrial applicability, the surface reflection method (SRM) is used instead of the traditional bottom reflection method (BRM) [14,15]. Based on the theory of elasticity and viscosity, the theory of the viscoelasticity evaluation method is researched.…”

The reflected waves received from ultrasonic waves propagating in materials contain information that constitutes the physical properties, material composition, defects, and degradation states. When measuring the dynamic viscoelasticity, the traditional bottom reflection method (BRM) cannot be used to measure the bottom irregular samples. In this paper, the storage modulus, loss modulus, and loss tangent are extracted by the surface reflection method (SRM) to evaluate the elastomer sample viscoelasticity. A theoretical study on the phase change caused by multiple reflections in the case of non-thin layer coupling is conducted. Based on this research, the experimental system is built. The results show that considering the thickness of the coupling layer can optimize the determination of viscoelasticity and reduce the error of the viscoelastic evaluation results of an elastomer with the traditional BRM. Finally, based on the principle of the SRM, the density of the elastomers is measured, and the feasibility and overall efficiency of this method are verified by experiments.
