Special Issue Information

Dear Colleagues,

Coastal and Offshore structures and applications must be designed to endure the harsh marine environment from multiple points of view. Either due to the extreme loading caused by waves and oceanic currents or related to marine phenomena such as corrosion and severe scour occurrence, among other aspects, applications in marine environmental conditions need to be simultaneously safe and efficient. Based on the design, installation and maintenance operations for these cases, properly considering the effects of extreme sea states is crucial. This Special Issue covers a broad set of contributions focused on methodologies to predict extreme sea states and other environmental conditions at sea, as well as research performed on the analysis, design, monitoring and behavior of coastal and offshore structures, energy harvesting devices, defense infrastructures, nature-based solutions, among others. From physical to numerical studies and in situ applications, all contributions to the importance of extreme sea states for maritime engineering are welcome in this Special Issue.

To analyze the impacts of groins, sandbars, and channels on the three-dimensional features of rip currents, we conducted experimental investigations on the vertical distribution of rip currents under intersecting waves along barred beaches with channels. This study employed ADV flow velocity measurements at two distinct locations: within channel and on a sandbar. The results indicate that in nodal sections within channel and on a sandbar, the rip head region manifests surface flow characteristics, characterized by high velocities near water surface. In a rip neck location, the vertical distribution of rip currents on a sandbar exhibits greater variability, whereas within channel, the distribution is more homogeneous. The vertical distribution of rip currents in nodal sections within channel aligns with the logarithmic distribution law. The vertical distributions of the alongshore velocity of rip currents display a consistent pattern of higher at the top and lower at the bottom. However, this pattern varies slightly depending on the wave period. The presence of groins influences the fluctuation characteristics of the alongshore velocity of rip currents by regulating the nearshore circulation system. This results in the alongshore velocity of rip currents in channel pointing towards the groin. In contrast, the alongshore velocity of rip currents on sandbar, situated farther away from groin, exerts a weaker effect on the alongshore velocity of a rip current. Full article
