Boussinesq Modeling of Alongshore Swash Zone Currents
The study involves theoretical formulation, model development and verification, and integration with field observations of swash motions. The starting point of the theoretical formulation is the Euler equation of motion for waves and currents above the permeable seabed and the locally-averaged Navier-Stokes equations for the flow inside the porous layer. A complete set of fully nonlinear Boussi...
متن کاملModulation of wave forces on kelp canopies by alongshore currents
The predominant view of the canopy-forming kelp’s mechanical response to water motion is that they sway passively under waves such that they are only rarely stretched out in flow, which reduces relative fluid velocities and decreases the applied force. Such a view is an appropriate first-order approximation but becomes conceptually problematic in the face of the net surface velocities (Stokes d...
متن کاملShelfbreak upwelling induced by alongshore currents: analytical and numerical results
Alongshore flow in the direction of propagation of coastal trapped waves can result in upwelling at the shelfbreak. The intensity of this upwelling can be comparable in magnitude to wind-driven coastal upwelling, with its associated ecological features. Recent numerical experiments by Matano & Palma indicate that this upwelling results from convergence of Ekman transport at the shelfbreak. The ...
متن کاملConsequences of Non-Uniform Active Currents in Dendrites
Thalamocortical (TC) neurons lead double lives: In a depolarized state near threshold excitatory synaptic input evokes regular spiking that faithfully " relays " information to the cortex, but when the cell is hyperpo-larized, the same excitatory input can lead to a low-threshold spike (LTS), triggered by low the threshold calcium T-currents (Figure 1). LTSs in TC cells occur during sleep, when...
متن کاملProposal for a Domain Wall Nano-Oscillator driven by Non-uniform Spin Currents
We propose a new mechanism and a related device concept for a robust, magnetic field tunable radio-frequency (rf) oscillator using the self oscillation of a magnetic domain wall subject to a uniform static magnetic field and a spatially non-uniform vertical dc spin current. The self oscillation of the domain wall is created as it translates periodically between two unstable positions, one being...
