The contribution to tidal asymmetry by different combinations of tidal constituents

Numerical simulation of the Adriatic Sea principal tidal constituents

The primary goal of this study was to incorporate data-derived harmonic constants into a complex dynamic model using a form of variational data assimilation, with a view to improve the prediction of 7 dominant tidal constituents in the Adriatic Sea. Firstly, harmonic-constant data for 6 Adriatic stations were fed into a steady-state, 3-D, forward/inverse model to furnish optimal boundary condit...

Tidal Turbines’ Layout in a Stream with Asymmetry and Misalignment

Abstract: A refined assessment of tidal currents variability is a prerequisite for successful turbine deployment in the marine environment. However, the numerical evaluation of the tidal kinetic energy resource relies, most of the time, on integrated parameters, such as the averaged or maximum stream powers. Predictions from a high resolution three-dimensional model are exploited here to charac...

Tidal Friction and Tidal Lagging. Applicability Limitations of a Popular Formula for the Tidal Torque

Tidal torques play a key role in rotational dynamics of celestial bodies. They govern these bodies’ tidal despinning and also participate in the subtle process of entrapment of these bodies into spin–orbit resonances. This makes tidal torques directly relevant to the studies of habitability of planets and their moons. Our work begins with an explanation of how friction and lagging should be bui...

Modeling the tidal and sub-tidal hydrodynamics in a shallow, micro-tidal estuary

Tidal Conversion by Subcritical Topography

Analytical estimates of the rate at which energy is extracted from the barotropic tide at topography and converted into internal gravity waves are given. The ocean is idealized as an inviscid, vertically unbounded fluid on the f plane. The gravity waves are treated by linear theory and freely escape to z 5 `. Several topographies are investigated: a sinusoidal ripple, a set of Gaussian bumps, a...
