Variability of Bed Drag on Cohesive Beds under Wave Action
Abstract: Drag force at the bed acting on water flow is a major control on water circulation and sediment transport. Bed drag has been thoroughly studied in sandy waters, but less so in muddy coastal waters. The variation of bed drag on a muddy shelf is investigated here using field observations of currents, waves, and sediment concentration collected during moderate wind and wave events. To es...
متن کاملConservation of wave action under multisymplectic discretizations
In this paper we discuss the conservation of wave action under numerical discretization by variational and multisymplectic methods. Both the general wave action conservation defined with respect to a smooth, periodic, one-parameter ensemble of flow realizations and the specific wave action based on an approximated and averaged Lagrangian are addressed in the numerical context. It is found that ...
متن کاملAn Interference Effect of Observed Biological Movement on Action
It has been proposed that actions are intrinsically linked to perception and that imagining, observing, preparing, or in any way representing an action excites the motor programs used to execute that same action. There is neurophysiological evidence that certain brain regions involved in executing actions are activated by the mere observation of action (the so-called "mirror system;" ). However...
متن کاملThe role of biophysical cohesion on subaqueous bed form size.
Biologically active, fine-grained sediment forms abundant sedimentary deposits on Earth's surface, and mixed mud-sand dominates many coasts, deltas, and estuaries. Our predictions of sediment transport and bed roughness in these environments presently rely on empirically based bed form predictors that are based exclusively on biologically inactive cohesionless silt, sand, and gravel. This appro...
متن کاملThe psychiatrist as archaeologist and architect
A colleague and I recently proposed a model to guide the description and reform of mental health services and to clarify service evaluation (Tansella & Thornicroft, 1998). The model, which we call the ‘mental health matrix’, consists of two dimensions, one temporal and one geographical. The temporal dimension comprises three phases: input (phase A), process (phase B) and outcome (phase C). The ...
