The hybrid system of wave energy converters (WECs) using coastal structures is an attractive issue in terms of a decrease in construction costs and an improvement of the ability to capture wave energy. Most studies on the utilization of reflected waves from structures, which is one of the hybrid systems, are limited to mathematical analysis based on linear theories. Therefore, this paper presents fundamental experimental results in the presence of a reflection wall simplified as a coastal structure behind a bottom-hinged flap-type WEC under unidirectional regular waves. The behavioral characteristics and the power generation efficiency ke of the flap were investigated, focusing on wave steepness, initial water depth, and distance from the reflection wall. The results show that the condition of the initial water depth being smaller than the flap height is more effective in terms of avoiding unstable rotating of the flap. The maximum ke appeared slightly far from the node position of the standing waves because the flap shape and the power take-off (PTO) damping induce the phase difference between the reciprocating behavior of the flap and the period of the standing wave. The results imply that the optimum position of a WEC is dependent on WEC shape, PTO damping, and installation water depth.

This study presents the characteristics of morphological evolution of clay/sand mixture and pure sand focusing on the clay loss on the surface layers under regular wave conditions. Hydraulic experiments were carried out using two-dimensional wave flume. Two different wave heights, 0.04 m and 0.07 m, with a wave period of 1.0 s were adopted. The movable beds consisted of silica sand (d50 = 0.439 mm) and kaolin (d50 = 8.0 µm) with the three different clay fractions, 0.0, 0.05 and 0.20. Regular waves were generated for more than 40 hours. Initial and final topography were measured with laser displacement meter and topographic change during experiments was estimated using the video taken with the camera on the side of the wave flume by means of image processing. In each case, the sediments were collected at the locations where the noticeable topographic changes occurred, and the change in clay fractions was examined. As a result, the higher the clay fraction, the smaller the initial topographic change. Over time, however, the similar morphological evolution of pure sand, such as sand ripples, was observed in the clay/sand mixture. The layer separation near the surface due to clay loss contributes to making the sand easier to move, thus separating surface layers into the clay-free layer (sand layer) over time implies an important factor in evaluating mixed soil transport.

<p> Climate change effects have become global concern through decades due to its emerging hazards. Sea Level Rise (SLR) is one of the effects which may cause harm to the coastal communities due to the risk of damages, such as shoreline retreat and beach erosion. There are many previous studies regarding the effect of SLR on sandy beaches. However, the study regarding gravel beach response under SLR is still rare. Therefore, this study is conducted to investigate the effect of SLR on the past shoreline change by using Bruun rule on currently eroded gravel beach, Ida beach in Shichiri-mihama coast, Mie Prefecture. By comparing the calculation result with the past shoreline change data obtained from network camera system, the proportion of SLR contribution in shoreline change can be assessed. Results shows that SLR contribution is ranging between 5.1 – 8.7% of the actual shoreline retreat from November 2017 to November 2019. This indicates that there are other factors such as extreme waves playing more dominant role in the shoreline change compared to SLR in this gravel beach.</p>

<p> We conducted numerical analysis on changes in dry bulk density, hydraulic experiments on changes in fine particle fraction under uniform flow. The effect of the change in density on the change characteristics of the topography consisting of mixed sediment was investigated. As a result, when considering the total suspended amount, in sandy mixed earth and sand, it was suggested that it is necessary to consider the increase in the total suspended amount due to the increase in the proportion of fine particles and the decrease in the suspended amount due to the increase in the adhesive strength in the adhesive mixed sediment and sand.</p>

<p> Two-dimensional hydraulic experiments were conducted using a reversed triangular bottom-hinged flap with the reflection wall behind it. Electricity generation performance when the power take-off system is installed was evaluated from the experimental result based on linear theory. Efficiency is lowest near the antinodes of the standing waves. There are some cases in which D/L when efficiency is highest is slightly different from nodes depends on wave period. Efficiency is high when the wave period is short and the water depth is small. There is a possibility that there is a specific wave period in which efficiency is extremely high. The increasing ratio of efficiency by installing the wall reached 6 at most and 2 at least.</p>

<p> The effectiveness and mechanism of flume-type anti-oscillation tanks against the motion of a floating caisson under regular waves was investigated from hydraulic experiments. From experimental results, it was found that the amplitude of heave was little affected by free water filled in the anti-oscillation tanks. In contrast, the maximum value of the amplitude of pitch tended to decrease with an increase in the mass of free water. From anti-oscillation moment due to free water estimated from image analysis, it was revealed that gravitational force due to the free water accounted for a substantial fraction of the anti-oscillation moment, while horizontal inertia force had an effect of increasing the amplitude of the anti-oscillation moment. Furthermore, analytical solutions of the amplitude of pitch estimated from the anti-oscillation moment agreed reasonably well with experimental results. This suggested that the mechanism of anti-oscillation tanks can be explained in the same way as in the field of naval architecture.</p>

<p> Tsunami-induced force acting on an inland building located at the landward side of a coastal protection facility with resilient structure combined with a coastal dike and an embankment was investigated numerically. Numerical results showed that the relationship between the tsunami force considering the erosion of the embankment and that assuming the constant profile of the embankment was affected by the scale of the erosion. This suggested that it is essential to take into account the erosion process of an embankment in assessing tsunami force acting on inland buildings.</p>

<p> This study describes the improvement of the image analysis of network camera using the orthomosaic created from UAV-SfM/MVS survey and the morphological characteristics of Shichiri-Mihama Ida beach based on the estimated shoreline positions extracted by a network camera and DEM obtained by UAV-SfM/MVS survey. The estimated shoreline extracted from the network camera image denotes the position in the range of 1~2 m above sea level by comparison with the DEM so that it was located on the land side from the actual shoreline. The application of the network camera including UAV-SfM/MVS survey makes it possible to identify the waves that caused the beach deformation between observations.</p>

<p> Numerical analyses of 1/55.8-scale small experiments and 1/4-scale large experiments on sand erosion under the rubble mound of a composite breakwater were conducted to investigate the effect of wave field on the time scale of the erosion. Numerical results showed that the time for the averaged flow inside the mound to be offshore throughout the mound and the time for the wave field around the breakwater to be equilibrium were longer in the small-scale experiments than in the large-scale experiments, and consequently the erosion observed in the large-scale experiments was underestimated in the small-scale experiments. This suggested that the time for the erosion to reach the same depth as that of the large-scale experiments was longer than that estimated according to the Froude similarity law.</p>

<p> The paper presents power generation characteristics of the proposed wave energy converter based on the bottom-hinged pendulum. The pendulum behavior becomes unstable and the power generation efficiency decreases when the wave energy is small, and the pendulum is installed at the position of <i>D/L</i> ≈ 0.5, which is the antinode of the standing wave. When the initial water depth was deeper than the pendulum, it was found that larger wave energy was required to rotate the pendulum stably. The maximum power generation efficiency (<i>k_e</i> = 0.77) was obtained at the position of <i>D/L</i> ≈ 0.32.</p>

<p> A temporary floating breakwater has been proposed to keep calm wave conditions in an offshore construction site. In this study, its wave damping mechanism was investigated from numerical simulations. Numerical results showed that the trend of the transmission coefficient can be predicted reasonably well. Furthermore, an energy damping coefficient of the breakwater changed depending on the breakwater width relative to the wavelength, and the change was explained in terms of vortices formed inside and under the breakwater. From numerical experiments, it was found that the barrier height of the breakwater and the free water depth poured inside the breakwater for most effectively reducing transmitted waves were dependence on the breakwater width relative to the wavelength.</p>

<p> In order to reduce the motion of a floating caisson, the effectiveness of a footing was investigated in terms of its width. Free oscillation experiments showed that the natural period of the pitch and the nonlinear extinction coefficients of the heave and pitch increased with the relative footing width. Forced oscillation experiments showed that the amplitude of the heave became large when the wave period was the same as the natural period of the heave. Similarly, the amplitude of the pitch increased when the wave period was one or two times larger than the natural period of the pitch. These suggested that it is essential to determine footing width considering the findings of this study.</p>

<p> In this study, to evaluate the effectiveness of the FS3M for assessing the countermeasures of beach erosion, the model was applied to the real-scale domain. We used the FS3M, which is a computational fluid dynamic model using the Navier-Stokes equation, and the survey data provided by Mie Prefecture. To address the problem of calculation cost, the numerical method called long-term estimation was used to calculate the evolution of the beach profile on the gravel beach. The validity of FS3M was investigated by applying the parameters used in the reflective type beach to the step type beach. The model reproduced well the position of the berm but shows a problem in the profile change under the water. However, in the process of wave propagation to the rear of the artificial reef, the reduction of the wave energy decreases the wave steepness, and the beach profile change for reflective type occurs predominantly. This fact shows that FS3M can be used to reproduce the beach profile change and evaluate the effects of artificial reef.</p>

<p> As a part of elucidation of the dynamic characteristics of fine particles considered to be an important factor in maintenance for tidal flat, we carried out a hydraulic model experiment focusing on the change of topography consisting of sand-clay mixed sediments by wave conditions and clay content. The characteristics of the topography and the influence of the spatial distribution of clay on the sediment characteristics of the mixed sediment were investigated. As a result, in the case of sediment consisted of clay and sand, the effect of the cohesion of clay was effective in delaying the topographic change. Mixed sediment was eroded by the movement of sand after clay particle is washed out. Moved sand covered mixed sediment and reduced the erosion.</p>

Furthermore, the FS3M was improved to compute unsaturated seepage flow more accurately. From comparison with experimental data, the predictive capability of the improved FS3M was demonstrated for unsaturated seepage in a dike and overflow-induced erosion of an unsaturated dike. This suggested the usefulness of the improved FS3M in assessing such phenomena related to unsaturated soil.</p>

From experimental and numerical results, it was found that the resilience of a trapezoidal caisson was higher than that of a rectangular caisson and an L-shaped caisson because the configuration of the trapezoidal caisson prevented the separation of the overflow and the formation of a vortex reducing an increase in wave pressure acting on the landward surface of the caisson.</p>

<p> The effectiveness of gabions against tsunami-induced scour at the landward toe of a coastal dike was investigated from hydraulic experiments. Experimental results showed that the installation of gabions moved a scour hole landward and reduced its maximum depth. This effect was reconfirmed from the hydraulic experiments in addition to existing numerical analyses not considering the leakage of sand and the displacement of gabions. Furthermore, it was found that a scour hole grew rapidly due to sand leakage after the gabions were displaced largely. This suggested that connected gabions could be more effective to reduce the displacement of the gabions and the gaps between the gabions.</p>

<p> The effectiveness of flume-type anti-oscillation tanks installed on a floating caisson in the pitch and roll directions under regular waves and multi-directional irregular waves was investigated from hydraulic experiments, and a simple numerical method for estimating the effect of the anti-oscillation tanks was developed and applied to the hydraulic experiments. From experimental results, it was revealed that the anti-oscillation tanks can reduce the pitch of the caisson increased at around the natural frequency and its double frequency under the regular waves. Furthermore, the anti-oscillation tanks were found to be effective against not only the pitch but also the roll under the multi-directional irregular waves. From numerical results, it was found that the effect of the anti-oscillation tanks can be estimated reasonably well in terms of the amplitude of the pitch. This suggested the usefulness of the developed method in estimating the most effective water volume in anti-oscillation tanks.</p>

Experimental results showed that the transmission coefficient decreased with an increase in the wave steepness and relative breakwater width. Furthermore, the time from the peak of the heave to that of the sway increased with the relative breakwater width and the temporal changes in the heave and sway had a nearly opposite phase for large relative breakwater widths, resulting in the abovementioned decrease in the transmission coefficient.</p>

<p> A three-dimensional coupled fluid-structure-sediment-seabed interaction model (FS3M) was applied to hydraulic experiments on the effectiveness of gabions against tsunami scour at the landward toe of a coastal dike. Numerical results showed that the predictive capability of the FS3M was demonstrated in terms of temporal change in the maximum scour depth for all conditions without the gabions and a small discharge condition with the gabions. From numerical results for a large discharge condition with the gabions, which subsided due to sand leakage in the hydraulic experiments, it was suggested that it was essential to take into account the subsidence of the gabions in accurately assessing the effectiveness of gabions.</p>

<p> This paper describes the method to calculate sediment transport in the mixed soil condition composed of sand and clay considering the change of clay contents due to clay loss. The concepts of the four-phase soil model and the maximum clay contents classifying mixed soil status were introduced into the method. The model incorporating the proposed method was tested under the experimental conditions. From the numerical results, when all the clay in the clay activation layer where clay loss can occur was flowed out, the suspended concentration of clay decreased with time similar to the experimental results. The suspended concentration of clay was remarkable at the offshore and onshore of the movable bed consisting of sand and clay, and the decrease of the clay content on the surface of the bed was confirmed in the same locations due to clay loss. Therefore, the proposed model suggests the possibility to improve the accuracy of sediment calculation in mixed soil condition and to clarify the mechanism of clay loss from the surface of mixed soil.</p>

Similar with the large-scale hydraulic experiments, sand seabed benearth the seaward part of the mound was eroded. However, the time at which this eroded depth reached to that for the large-scale hydraulic experiments needed to be longer than the time determined according to the Froude similarity law. This suggested that further studies are required for the time scale of the erosion of the sand seabed benearth the mound.</p>
