On the Calculation of Tidal Currents in Homogeneous Estuaries
Tidal Currents Homogeneous Estuaries
font style='font-size:12px;'>
2009/3/7
This paper describes a new approach to the computation of tidal flow in homogeneous estuaries with irregular boundary configurations and of arbitrary depth. The governing equations are the standard ve...
Topographic Rectification of Tidal Currents on the Sides of Georges Bank
Topographic Rectification Georges Bank Tidal Currents
font style='font-size:12px;'>
2009/2/18
The rectification of M2 tidal currents on the sloping sides of Georges Bank is predicted to make an important year-round contribution to its observed mean clockwise circulation. A rectification mechan...
Observed and Computed M2 Tidal Currents in the North Sea
Computed M2 Tidal Currents North Sea
font style='font-size:12px;'>
2009/2/16
M2 tidal elevations and currents have been computed using a three-dimensional hydrodynamic numerical model of the northwest European shelf. These have been compared with observational data from tide g...
The Interaction of Wind-Generated Sea Waves with Tidal Currents
Wind-Generated Sea Waves Tidal Currents Interaction
font style='font-size:12px;'>
2009/2/13
The interaction between wind-generated surface waves and tidal currents ran be described in terms either of the energy balance of the system or of the conservation of wave action, assuming that the ti...
The Generation of Diurnal Period Shelf Waves by Tidal Currents
Diurnal Period Shelf Waves Tidal Currents
font style='font-size:12px;'>
2009/2/7
Continental shelf waves of diurnal period are shown to be generated by tidally induced Reynolds stresses within a bottom Stokes-scale boundary layer. The theory is applicable to a uniformly rotating, ...
A Simple Method for Estimating Barotropic Tidal Currents on Continental Margins with Specific Application to the M2 Tide off the Atlantic and Pacific Coasts of the United States
Barotropic Tidal Currents United States Continental Margins
font style='font-size:12px;'>
2009/2/7
Theory is developed to describe barotropic tidal currents on “smooth” continental shelves, that is, continental shelves with longshore scales much greater than the shelf width. Two models are consider...
Vertical Variations of Tidal Currents in Shallow Land Fast Ice-Covered Regions
Vertical Variations Ice-Covered Regions Tidal Currents
font style='font-size:12px;'>
2009/1/4
Arctic tidal currents with periods near the local inertial period are strongest and rotate clockwise at mid-depth, and decrease in amplitude towards the bottom and ice-cover, experiencing a change in ...
Examining the Influence of Wind and Wind Wave Turbulence on Tidal Currents, Using a Three-Dimensional Hydrodynamic Model Including Wave–Current Interaction
three-dimensional hydrodynamic model bottom friction flow-dependent eddy viscosity
font style='font-size:12px;'>
2008/12/17
This paper presents a very brief overview of the development of a three-dimensional hydrodynamic model involving a flow-dependent eddy viscosity and including enhancements of bottom friction due to wa...
Amplification of Tidal Currents by Overflow on the Iceland-Faeroe Ridge
Tidal Currents Iceland-Faeroe Ridge Overflow
font style='font-size:12px;'>
2008/12/15
During several days in July 1990, there was an abrupt increase in semidiurnal tidal current in the upper part of the water column seaward of the steep continental rise southeast of Iceland. This tidal...
Application of Turbulence Energy Models to the Computation of Tidal Currents and Mixing Intensities in Shelf Edge Regions
Tidal Currents Shelf Edge Regions Mixing Intensities
font style='font-size:12px;'>
2008/12/9
The major steps in the formulation of a three-dimensional shelf edge model using a sigma coordinate system in the vertical are briefly described. Vertical diffusion of momentum is parameterized using ...

Effects of turbulence-mediated larval behavior on larval supply and settlement in tidal currents
turbulence-mediated larval larval supply settlement in tidal currents
font style='font-size:12px;'>
2014/4/22
Intertidal gastropod larvae retract their vela and sink in strong turbulence, and this behavior potentially increases settlement in turbulent coastal habitats. We incorporated turbulence-induced sinki...
