“…Creating a reservoir at the top crest of structure which serves to capture the over-topping discharge through the wave run-up is the idea behind the SSG structures. 15 The SSG mechanism produces differential water level between reservoir and still sea water level as a pressure head, 15 which is responsible for creating energy.…”

The applicability of Sea-wave Slot-cone Generator breakwater as a system of energy converter in the southern coasts of Iran is investigated. Several efficient factors simultaneously have been considered, including the period and the significant height of wave, the effective depth, and the hydraulic efficiency. The field data used in this study are those derived from the stationary buoys. Findings reveal that Asaluyeh and Shahid-Beheshti ports are the only places, which might satisfy the required needs. The percentage of hydraulic efficiency achieved, however, is less than what is suggested in the literature as the minimum acceptable level. In other words, the use of Sea-wave Slot-cone Generator breakwater is not financially affordable in the southern coasts of Iran.

“…Figure 3 shows that the rate of q (overtopping discharge) in the regular wave condition is much larger than the Van Der Meer rate in the irregular wave conditions. Thaha et al [7] also estimated the wave power that can be captured by the model is about 34% on average. The graph shown in Figure 4.…”

“…Thaha et al in previous research [7] was conducted by physical model simulations under regular wave conditions compared to the Van Der Mer result in irregular wave conditions. The results showed an over-topping discharge (q) is significantly influenced by the parameters of the breakwater free-board relative to the wave height (Rc/Hi).…”

“…4. The wave power availability and potentially mobilized [7] The research result in Figure 4 shows that the waves are a huge potential energy source in the field. Not only because the wave power estimation that can be captured from the model is quite high, but the model has also a high economic and financial feasibility, because the model is made possible from the breakwater or coastal protection structure, so it can have multiple function as coastal defense and also wave energy converter.…”

Single Slope Shore Protection as a Wave Energy Catcher

et al. 2018

Wave energy is being increasingly regarded in many countries as a major, promising and renewable resource. This paper presents the development of slope coastal protection as a wave energy converter by capturing sea water into the reservoir through overtopping process. Physical models simulation were conducted at The Laboratory of Coastal Engineering, Hasanuddin University. A model of 30 cm x 90 cm in the 30° degree of slope made from acrylic material equipped with a reservoir at the top surface of the structures to catch seawater through run up and overtopping. Models were simulated with various wave high and periods as well as high of freeboard. The results showed that the overtopping discharge (Q) much influenced by relative freeboard height (Fb/d), wave steepness (Hi/L), reflected waves (Kr) and the number of standing waves (Nsw). The increasing Fb, the decreasing Q; the increasing wave steepness, the increasing overtopping discharge. It was found that the larger the reflection coefficient, the greater the discharge overtopping. Standing waves in front of the structure due to the superposition of the incident wave and reflection waves also contribute to enlarge the overtopping discharge.
