(eds.), Integrating Biophysical Components in Coastal Engineering Practices. Journal of Coastal Research, Special Issue No. 92, pp. 121–127. Coconut Creek (Florida), ISSN 0749-0208.Rip currents are seaward directed flows responsible for drownings and lifeguard rescues efforts all over the world. However, these currents have not yet received the proper attention from society and decision makers. A significant dataset was gathered during 25 field surveys at Reserva Beach, which is a microtidal intermediate beach in Rio de Janeiro city (Brazil). The data established a correlation among rip currents (magnitude and direction), tides (range and phase), and wave parameters (height, period, and angle of incidence). The most intense rip currents were typically observed during large wave height and shore-normal incidence. These were the two parameters that most influenced the intensity of the currents. Even though the area is characterized by a microtidal regime, tidal modulation was observed. The Reserva beach could be divided into three areas, regarding the frequency and intensity of rip currents. Two lateral areas were classified as “hazardous areas”, and a central region was classified as a “safe area”.

To develop beach engineering, the submerged structure’s primary physical functions have to be understood. This study focuses on submerged structures in order to understand the strategy of reduced wave energy, stabilizing the shoreline and not generating erosion or adversely modifying coastal processes. Important developments have been made since the 1990s, taking into account the functions of recreational amenity. However, non-dimensional models cannot explain the physical mechanisms that generate accretion or erosion morphological features in the lee of the submerged structure. The present study aims to collaborate with the understanding of the mechanism of beach response to a submerged structure. For this, 26 surveys were made using topographic, Lagrangian, and Eulerian hydrodynamic measures during one seasonal cycle of a beach system from Rio de Janeiro (Brazil) with a natural submerged reef or rocky bank V-shape in the plan. This beach system is energetic and intermediate when referring to wave energy conditions and beach states, respectively. The wave breaking vector system on the rocky bank’s geometry was examined in the intermediate and dissipative beach morphodynamic organization. The variability of the wave breaking vector system determines the establishment, deformation, and erosion features in the lee of the structure. During high-energy waves, the submerged structure’s hydrodynamic and morphodynamic processes are transparent. When the submerged structure combines with the dissipative beach state, the surfing wave conditions are improved. These results provide the dimensional and positional references for an engineering proposal for a beach system.
