“… 23 The majority of Terengganu's beaches consist of both natural and man-made beach dunes, serving as protective barriers over sandy coastlines against high waves and water levels during severe storms. However, the monsoonal regime in this region, particularly during the northeast monsoon, 24 combined with various topographic conditions, has led to the loss of many parts of the beaches in Terengganu, disrupting the natural equilibrium of sediment balance and the longshore sediment drift circulation. The impact of the monsoon on Terengganu coastal erosion has also been investigated by incorporating the rainfall variable into the CVI.…”

“…They possibly force the sea turtles to stay away and lay eggs in a lower section of beach berm, which is more susceptible to erosion and inundation [ [82] , [83] , [84] , [85] ]. Revetments and seawalls were shown to have adverse effects on sea turtle nesting, where fewer turtles emerged onto beaches in front of revetments and returned to the water without nesting when compared to adjacent beaches [ 86 , 87 ]. It was further explained that the presence of the revetments impeded the turtles from accessing an upper part of the beach, thereby encroaching sea turtles and degrading suitable nesting habitats.…”

“…The solutions that have been proposed to address these problems have been totally dependent on traditional structures, such as seawalls, breakwaters, and other structures [10][11][12][13][14]. While these structures have solved specific problems of coastal protection in the short (several years) and medium term (one decade), they have been incapable of addressing issues such as the sea level rise in the long term (several decades) [15,16].…”

An analysis of the interactions between wave-induced velocities and seagrass meadows has been conducted based on the large-scale CIEM wave flume data. Incident irregular wave trains act on an initial 1:15 sand beach profile with measurement stations from the offshore of a surrogate meadow until the outer breaking zone, after crossing the seagrass meadow. The analysis considers variability and peaks of velocities, together with their skewness and asymmetry, to determine the effects of the seagrass meadow on the near bed sediment transport. Velocity variability was characterized by the standard deviation, and the greatest changes were found in the area right behind the meadow. In this zone, the negative peak velocities decreased by up to 20.3%, and the positive peak velocities increased by up to 11.7%. For more onshore positions, the negative and positive peak velocities similarly decreased and increased in most of the studied stations. A progressive increase in skewness as the waves passed through the meadow, together with a slight decrease in asymmetry, was observed and associated with the meadow effect. Moving shoreward along the profile, the values of skewness and asymmetry increased progressively relative to the position of the main sandbar. The megaripple-like bedforms appeared earlier when the meadow was present due to the higher skewness, showing a belated development in the layout without the meadow, when skewness increased further offshore due to the proximity of the breaker sandbar. To assess the sediment transport capacity of a submerged meadow, the SANTOSS formula was applied, showing that in front of the meadow, there was a higher sediment transport capacity, whereas behind the meadow, that capacity could be reduced by up to 41.3%. In addition, this formula was able to produce a suitable estimate of sediment transport across the profile, although it could not properly estimate the sediment volumes associated with the bedforms generated in the profile.
