Seabed roughness due to wave ripples is a key factor in controlling sediment transport processes the nearshore zone. Roughness commonly considered function of ripple geometry, which turn, can be predicted from and hydrodynamic parameters. Existing predictors consider bed morphology equilibrium with hydrodynamics, whereas recent laboratory measurements show that time scale for development order tens minutes hours. Here we on tidal beaches are significantly affected by relaxation effects,...
Austin, M.J.; Scott, T.M.; Russell, P.E., and Masselink, G., 2013. Rip current prediction: development, validation, evaluation of an operational tool. This contribution details the rip prediction Field measurements dynamics from a macrotidal beach in southwest U.K. collected over 87 tidal cycles indicate that currents are highly dynamic range temporal spatial scales. The morphology lower intertidal face provides primary control currents, whereas variation pattern wave dissipation due to...
Abstract. Tidal flow past offshore wind farm (OWF) infrastructure generates a turbulent vortex wake. The wake is hypothesised to enhance seabed stress and water column turbulence mixing, thereby affecting mobility, stratification the transport of nutrients oxygen resulting in ecological impacts. We collect novel hydrodynamic data 40 m from an OWF monopile over spring–neap cycle use high-frequency velocity measurements quantify turbulence. Outside wake, we observe classical depth-limited...
The UN Agenda 2030 promotes safe access to green spaces, and the Ocean Decade aims enhance humanity’s preparedness for ocean hazards its relationship with ocean. tide is not considered an hazard, yet half of world’s coastline susceptible tides rising more than two meters in a single tidal cycle globally >300,000 people per annum lose their lives drowning. We undertook first nationally representative survey public understanding tide, revealing that over quarter British Irish struggled...
Abstract We present for the first time observations and model simulations of wave transformation across sloping (Type A) rock shore platforms. Pressure measurements water surface elevation using up to 15 sensors five platforms with contrasting roughness, gradient, climate represent most extensive collected, both in terms range environmental conditions, temporal spatial resolution. Platforms are shown dissipate incident infragravity energy as skewness asymmetry develop and, line previous...
Extensive measurements of ripple characteristics and dynamics along with associated suspended sediment fluxes hydrodynamic conditions were made in the shoaling surf zones a macrotidal coarse grained beach at Sennen Cove, Cornwall, England (median grain diameter 0.69 mm). Suborbital vortex ripples observed during majority study period height ∼5 cm length ∼35 cm. The scale shape did not vary significantly as bed shear stress increased wave breaking. However, migration rates (onshore directed)...
Field measurements and numerical modelling have been used to investigate the water-level control of rip current dynamics on a macro-tidal beach. data collected over 32 complete tidal cycles, spanning range wave tide conditions, demonstrate that strength behaviour is modulated at semi-diurnal frequency by tide-induced changes in bar/rip morphology. Peak flow speeds neck 〈uv〉 correspond time maximum breaking 1.5 h before after low water. Alongshore-directed water surface gradients ∂η/∂y were...
The world's shallow continental shelves are currently experiencing a rapid pace of development from the growth offshore renewable energy. emplacement infrastructure on seabed can change morphology bed, nature flow above it transport sediment, and so complicate assessment stability for planning designing infrastructure. To ascertain how much an impact these natural processes have cables, we present first field observations made directly over section subsea cable, two deployments in Eastern...
