Breakwaters have been built since antiquity to protect anchorages, helping isolate vessels from marine hazards such as wind-driven waves. [1] A breakwater, also known in some contexts as a jetty or a mole , may be connected to land or freestanding, and may contain a walkway or road for vehicle access.
Hence, the blocks easily find a position that fully utilizes the interlocking mechanism. This increases the efficiency of placing armour units on a slope. [ 9 ] Due to the random structure and high porosity of an Xbloc breakwater, an artificial reef habitat is created for marine fauna and flora.
A submarine pipeline (also known as marine, subsea or offshore pipeline) is a pipeline that is laid on the seabed or below it inside a trench. [ 1 ] [ 2 ] In some cases, the pipeline is mostly on-land but in places it crosses water expanses, such as small seas, straits and rivers. [ 3 ]
A dolos (plural: dolosse [1]: 10 ) is a wave-dissipating concrete block used in great numbers as a form of coastal management. It is a type of tetrapod. Weighing up to 8 tonnes (8.8 short tons), dolosse are used to build revetments for protection against the erosive force of waves from a body of water.
A tetrapod is a form of wave-dissipating concrete block used to prevent erosion caused by weather and longshore drift, primarily to enforce coastal structures such as seawalls and breakwaters. Tetrapods are made of concrete , and use a tetrahedral shape to dissipate the force of incoming waves by allowing water to flow around rather than ...
Marine construction is the process of building structures in or adjacent to large bodies of water, usually the sea. These structures can be built for a variety of purposes, including transportation, energy production, and recreation. Marine construction can involve the use of a variety of building materials, predominantly steel and concrete ...
Both types of water can circulate in marine sediments due to tidal pumping, waves, bottom currents or density driven transport processes. Meteoric freshwaters can discharge along confined and unconfined aquifers into the sea or the oppositional process of seawater intruding into groundwater charged aquifers can take place. [ 1 ]
Submarine groundwater discharge= meteoric water + freshwater from aquifers + recirculated seawater. Modified from Pacific Coastal and Marine Science Center (2021). [30] Submarine groundwater discharge (SGD) is the groundwater flows across the interface of the aquifer and the sea. It refers to the flow of water shifting towards the sea. [31]
