Sand Sealing of Coastal Structures
DISCUSSION: Rubblemound coastal structures contain voids between individual armor units. Structure voids maximize turbulent wave energy dissipation, but also allow passage of water and sediment. The volume of sediment passing through some jetties and terminal groins can be substantial, resulting in increased channel shoaling, higher maintenance costs, and significant loss of beach material. Mos...
متن کاملSimulation of Wave Propagation over Coastal Structures Using WCSPH Method
In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with th...
متن کاملSide-scan Sonar for Inspecting Coastal Structures
INTRODUCTION: SSS has been used to map the sea bottom and search for submerged objects since the 1960's (Fleming, 1976). Recent experiments by CERC and the Buffalo District have shown SSS to be useful for inspecting both sloping coastal structures (i.e., rubble-mound jetties and breakwaters) and vertical-wall structures (i.e., concrete caissons and timber cribs). SSS is an adaptation of high-fr...
متن کاملinvestigating the ancient siraf’s coastal architectural structures by underwater archaeology
some researchers believe that because of the severe earthquake and tsunami in the fourth century h., a large part of siraf submerged by the persian gulf water fluctuations. based on the available evidence and also by the archaeological survey of the siraf coastal surrounding areas, the author argues that despite the devastating earthquake occurred to destroy much of the coastal architectural st...
متن کاملEffect of Seawater on Micro-Nano Air Bubbles Concrete for Repair of Coastal Structures
This paper investigated the effects of seawater curing of concrete made by Micro-Nano Air Bubbles (MNAB) on compressive, flexural and tensile strengths of the concrete. This product will be applicable for rehabilitation or repair of coastal RC structures. In this research, the effect of different combinations of concrete ingredients including 0-100, 25-75, 50-50, 75-25, and 100-0 percent ...
