Numerical Modeling of Breaking Waves and Cross-Shore Currents on Barred …
Web24 Jul 2014 · More specifically, the wave-induced cross-shore current, called undertow, represents one of the dominant forces behind sandbar formation, offshore sediment transport, and beach erosion (Dally 1987; Larson and Kraus 1989; Ruessink et al. 2007; Kuriyama 2012; Abreu et al. 2013; Dubarbier et al. 2013 ). WebThe spatial distribution of the mean cross-shore flow (undertow) over a barred beach is examined with field data obtained on three energetic wave days during the Duck94 experiment. The vertical structure of the undertow is modeled using a turbulent eddy viscosity closure and includes the important effects of wave breaking (described using … figs and olives natick
Wave Transformation and Undertow Over a Barred Beach
Web3.04.3.3.1 Undertow. Ideally, undertow is a two-dimensional (2D) return flow that occurs uniformly alongshore and is manifested as an offshore-directed net flow below the level of the wave troughs (Figure 14 ). Because flow occurs uniformly alongshore the current speeds are relatively low, usually on the order of a 3–10 cm s −1 under ... WebWave Transformation and Undertow Over a Barred Beach Fujii, E. ; Özkan-Haller, H. ; Long, J. The mean cross-shore flow (undertow) over a barred beach is examined by calibrating an … Webundertow and sawtooth-shaped nonlinear wave motion over the cross-shore evolution of barred (storm) and nonbarred (normal) beach profiles. The bottom elevations, free-surface motion, and flow velocity were measured under regular wave conditions, excluding infragravity waves, over a movable bed. The observations were conducted in the surf zone … figs and olives menu
