The necessity to implement solutions that guarantee the protection and recovery of the coastal area makes that the submerged breakwater employment is evaluated as a viable variant of application because these works contribute to the conservation of the nat ural and aesthetic conditions of the beaches, which is part of the tourist product that...

... morphological variables. A non-equidistant working mesh was established using profiles measured on the Varadero beach to which the equilibrium profile was determined using the expression given by García (2005) for the sediment scale parameter, which presents a better fit for characterizing the conditions of Cuban biogenic beaches (Figure 1). The mesh covers an area of 492 000 m 2 comprised by 615 m in a perpendicular direction to the coast with a resolution of 5 m (123 nodes) and 800 m along the coast with a resolution of 10 m (80 nodes), with Open Access bajo la licencia CC BY-NC-SA 4.0 (https://creativecommons.org/licenses/by-nc-sa/4.0/) depths starting from the 8m isobath to reaching heights of 3 m above mean sea level in the dune area, which allowed us to visualize the processes that occurred in each simulation. ...

In Figure 11 these patterns are observed, with the retreat of the coastline for both the 10 m wide crest breakwater and the 20 m wide breakwater, with the latter being more pronounced, where the red line represents the init ial position of the coast. ...

When observing the behavior of Profile 41, which passes through the center of the 100 m long breakwater, the morphological evolution of the seabed is noted, where the coastline presents loss of sediment and retreat, as seen in Figure 13. ...

For the 20 m wide breakwater, there is marked erosion throughout the profile, which intensifies at its base due to increased flow velocities, which could cause the failure of the structure. ...

... effect of submergence is observed through the transmission coefficient in Figure 14, where for 0.00 m submergence breakwaters the values decrease until very close to zero while they increase with the increase in submergence until reaching values of 0.54 for breakwaters with the submergence of -1.00 m. ...

... 9 and Table 10 show the transmission coefficients and wave setup for breakwaters located 60 m from the coast with 100 m, 200 m, and 300 m in length under the oblique action of the waves, which can be compared with Tables 3 and 6 where the waves act perpendicular to the coast. The patterns of flow and circulation of the currents present a behavior similar to that observed for the waves acting normal to the coast, with the retreat of the coastline for the nearby locations, as shown in Figure 16. The morphological evolution of the seabed under the oblique incidence of the waves can be observed in Figure 17, where the coastline presents a behavior very similar to that obtained under the waves acting perpendicular to the coast, with loss of sediment and retreat, which shows that the obliquity of the waves does not exert significant influence in coastal response mode. ...

... analysis was carried out by varying the distances to the coastline, locating the breakwaters at 30, 60, 90, 120, 150, 180, 210, 240, 270, and 300 m apart. The effect of the breakwater placement distance on the mean square height of gravity waves and on the transmission, coefficient is shown in Figure 18, which decreases as the breakwater moves away from the coast, corresponding to the lowest values in all the cases to the 20 m wide breakwaters.

Mangroves and moored barges are used individually for coastal protection and beach restoration. This conceptual paper discusses about the integration of mangroves with moored floating barges for coastal protection. The concept involves towing of a barge to a particular location, mooring it to the seafloor and planting mangroves along the shore or b...
