Posidonia oceanica, the most abundant seagrass species in Mediterranean, supports a highly bio-diverse habitat and is crucial protecting against coastal erosion. In this work, experiments large-scale facility have been performed, for measurement of wave attenuation, transmission energy dissipation over artificial oceanica. The effects submergence ratio corresponding to height divided by water depth, density as number stems per square metre on above characteristics are investigated....
Coastal restoration is often distrusted and, at best, implemented small scales, which hampers its potential for coastal adaptation. Present technical, economic and management barriers stem from sectoral poorly coordinated local interventions, are insufficiently monitored maintained, precluding the upscaling required to build up confidence in ecosystem restoration. The paper posits that there enough knowledge, technology, financial governance capabilities increasing pace scale of restoration,...
Wave breaking plays a crucial role in several areas of interest coastal engineering, such as flooding, wave loading on structures and morphodynamics. In the present study, Smoothed Particle Hydrodynamics (SPH) simulations monochromatic waves over rigid barred beach profile are presented. The numerical results comprise heights, phase average velocities, time-averaged vorticity dynamics, radiation stress, validated versus detailed water surface velocity measurements carried out large-scale...
Two computational models, Simulating WAve till SHore (SWASH) and DualSPHysics, with different costs capabilities have been hybridized in this work. SWASH is a time-domain wave model based on finite difference method for simulating nonhydrostatic, free-surface rotational flow while DualSPHysics Lagrangian mesh-less the Smoothed Particle Hydrodynamics (SPH) technique. reliable to generate propagate waves large domains, whereas normally used areas close coastline provide detailed description of...
Abstract A large‐scale wave flume experiment has been carried out involving a T = 4 s regular with H 0.85 m height plunging over fixed barred beach profile. Velocity profiles were measured at 12 locations along the breaker bar using LDA and ADV. strong undertow is generated reaching magnitudes of 0.8 m/s on shoreward side bar. circulation pattern occurs between breaking area inner surf zone. Time‐averaged turbulent kinetic energy (TKE) largest in where jet penetrates water column. At this...
Abstract Detailed measurements are presented of velocities and turbulence under a large‐scale regular plunging breaking wave in flume. Measurements were obtained at 12 cross‐shore locations around mobile medium‐sand breaker bar. They focused particularly on the dynamics bottom boundary layer (WBL) near‐bed turbulent kinetic energy (TKE), measured with an Acoustic Concentration Velocity Profiler (ACVP). The process outer flow hydrodynamics agreement previous laboratory field observations...
Coastal systems are experiencing increasing pressures and degradation due to climatic anthropic factors, projected escalate under future scenarios. Such an increase will require more natural economic resources maintain coastal zones the way we know them, leading competing often incompatible uses for scant fresh water, sand volumes or accommodation space. Without proactive measures, current protection strategies face exacerbating vulnerabilities, resulting in unsustainable risk levels...
A novel flume experiment was conducted to compare the sheltering effect of surrogate seagrass meadows two different lengths against a bare beach (benchmark). The analyses focused on assessing impact meadow cross-shore extent wave height attenuation, behaviour orbital velocity components, sediment transport, and shoreline erosion. Throughout tests in large-scale CIEM at LIM/UPC Barcelona, density submergence ratio remained constant, while irregular waves were run over an initial 1:15 sand...
Abstract Large‐scale wave flume experiments are conducted in the ripple vortex regime to study near bed coarse sand transport processes below asymmetric surface waves typical of coastal nearshore region. For this purpose, a set complementary acoustic instruments were deployed under regular conditions. Time‐resolved velocity, concentration and flux profiles measured across both dense bedload dilute suspension layers with an Acoustic Concentration Velocity Profiler. The equilibrium 2D...
Abstract This study presents novel insights into hydrodynamics and sediment fluxes in large‐scale laboratory experiments with bichromatic wave groups on a relatively steep initial beach slope (1:15). An Acoustic Concentration Velocity Profiler provided detailed information of velocity sand concentration near the bed from shoaling up to outer breaking zone including suspended sheet flow transport. The morphological evolution was characterized by offshore migration breaker bar. Decomposition...
