Important ports with many economic activities are located along the sea coasts, therefor breakwaters are usually built to protect the beaches against waves and floods, especially if these coastal areas have a high population density. In this paper three models of coastal structures will be tested.
A new concept for wave dissipating & conversing energy are examined to proof the concept for generating electricity using three different Physical Models. Vertical Seawall with different porosities to analyze the preliminary efficiency of these devices.
For an Economic expansion continuously requires additional for construction Seawalls for protecting shore line and it could be possible to include some changes inside the body of the wall for proposed to generating energy.
Concrete blocks are usually used in breakwaters, which are placed in front of the vertical breakwater and dissipate part of the energy of the incoming wave. The energy dissipation efficiency of the perforated structure can be directly evaluated by reflecting and absorbing the wave from the breakwater.
Due to the complex properties that depend on the interaction between the waves and the porous medium of the breakwater body, three laboratory models were used to verify the reflection, absorption and crash of the wave on the tested breakwater body.
To explore the characteristics of wave interaction with the porous structure, many numerical models based on the Navier–Stokes equations were presented by using numerical techniques such as, Dalrymple et al. (1991).
For the interaction between the permeable structure and water waves, which is able to consider the wave breaking in three-dimensional wave field, Mizutani et al., (2000).
For investigation the field of flow caused by the movement of the waves and the movement of water molecules in and around the vertical permeable structure, which is affected by the interaction between the waves and the porous medium of the barrier body. Therefore, a fully non-linear three-dimensional numerical model has been developed to study these interactions between waves and wave barriers that have a percentage of permeability., Aliasghar Golsh; et al., (2002).
Describing how to apply a numerical model to a partially perforated-vertical wall caisson and irregular waves. By testing the performance of this model, existing experimental data are used for regular waves, while a laboratory experiment is conducted in this study for irregular waves, Kyung-Duck Suh et al. (2004).
The numerical results are validated with the experimental data of surface elevations and wave pressures acting on the caisson breakwater, Chiu, Y.F., et al., (2007).
Proposes a new concept for a system of wave energy conversion. The objective of this research was to create and test a new system for wave energy converter that can be integrated within a breakwater. In this new concept the primary function of this device will remain the protection of the harbor, Joris Schoolderman, et al. (2010).
The hydrodynamic efficiency of the seawall is presented as a function of the wave run-up, reflection, and energy dissipation coefficients. Different wave and structural parameters affecting the seawall efficiency are investigated, El-Sadek M. Heikal, et al., (2012).
A qualitative progress is introduced with three-dimensional models, these are not so limited because they reproduce full 3D wave transformation processes, as diffraction, which typically occur on breakwater heads. Del Jesus et al., 2012; Lara et al., 2012; Higuera et al., (2013).
Testing four different simple, single porous vertical blocks using regular waves. These additional tests represent slightly more complex configurations including double blocks, reflective boundaries, irregular waves and sloping structures, Jeroen et al., (2014).
Interaction between the wave and the partial perforated caisson in a 2D numerical wave flume is investigated by means of the renewed SPH algorithm, and the mathematical equations are in the
form of SPH numerical approximation based on Navier–Stokes equations, JIANG Fe., et al., (2015).
A review and validation of control strategies for massive wave energy conversion systems, briefly outlines the characteristics of ocean wave energy, and summarizes the principles of ocean and sea energy aggregation by studying the specific wave energy transformers and commercial devices deployed in the real sea between 2005 and 2016, Liguo et al., (2017).

For examiner of the process of advanced ocean environment replication starting from the sea and ending to the tank, and rather than an exhaustive overview of all approaches, it follows the rationale behind projects led, S. Draycott et al., (2019).
the generation of renewable energy in transition is energy and economic cost. Southeast Asia therefore has several enormous potentials for its sustainable energy sources. However, to date they have not yet performed globally ahead in renewable energy deployment due to various challenges, Erdiwansyah et al, (2019).
An innovative vertical breakwater cross-section integrating an overtopping wave energy converter, named OBREC-V, and the analysis of its hydraulic performance and stability response to hydraulic loading. The structure is consisting of a vertically-faced caisson with a sloping ramp on the top, a reservoir and a set-back crown-wall, Enrico Di Lauro, et al. (2020).
