Predicting Changes in Tidal Regime：The Open Boundary Problem
Tidal Regime The Open Boundary Problem Predicting Changes
2009/3/7
Attempts to predict the impact on a tidal regime of large engineering structures are generally based on the use of a numerical model which is calibrated to reproduce the natural tidal regime and then ...
Response of suspended sediment concentration to tidal dynamics at a site inside the mouth of an inlet: Jiaozhou Bay (China)
sediment concentration suspension advection currents shoalling effect Jiaozhou Bay China
2009/3/4
Observations of fair weather currents and suspended sediment concentrations (SSC) were made using an acoustic Doppler current profiler and two YSI turbidity sensors over a neap to spring time cycle at...
The Modeling of Tidal Flow in a Channel Using a Turbulence Energy Closure Scheme
Turbulence Energy Closure Scheme Tidal Flow
2009/2/23
A parameterization scheme is developed that is suitable for the modeling of turbulence in marine systems and an application is made to the determination of the tidal structure in an elongated channel....
Non-Tidal Variability in the Chesapeake Bay and Potomac River：Evidence for Non-Local Forcing
Non-Tidal Variability Chesapeake Bay Potomac River Non-Local Forcing
2009/2/23
Non-tidal variability in the Chesapeake Bay and Potomac River, and its relation to atmospheric forcing, is examined from two-month sea level and bottom current measurements. The dominant sea level flu...
Some Effects of an Elliptic Ridge on Waves of Tidal Frequency
Elliptic Ridge Waves Tidal Frequency
2009/2/23
A numerical finite-difference model using the Laplace tidal equations on an f-plane was developed to predict how tidal motion is disturbed by an elliptic ridge. With the use of an open-ocean matching ...
A Study of Tidal Energy Dissipation and Bottom Stress in an Estuary
Tidal Energy Dissipation Bottom Stress Estuary
2009/2/19
A Method for inferring an area-averaged bottom stress and energy dissipation rate in a tidal estuarine channel is presented. The one-dimensional continuity and momentum relations are developed using s...
A new general theory has been developed to determine both the tidal response of estuaries and the effects of cross-channel tidal barriers on this response. The theory is shown to be widely applicable ...
Tidal Exchange through a Strait：A Numerical Experiment Using a Simple Model Basin
Tidal Exchange Simple Model Basin Strait
2009/2/19
In order to investigate the mechanism of tidal exchange through a strait, we numerically track the Lagrangian movement of water particles over a full cycle of the M2 tide. As a result, it is found tha...
Topographic Rectification of Tidal Currents on the Sides of Georges Bank
Topographic Rectification Georges Bank Tidal Currents
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...
The Relationship of Tidal and Low-Frequency Currents on the North Slope of Georges Bank
Tidal Low-Frequency Currents North Slope of Georges Bank
2009/2/18
Measured currents at the steeply sloping north edge of Georges Bank show an unusually strong correlation between tidal and lower frequency components. The dominant current constituents are the rotary ...
Observed and Computed M2 Tidal Currents in the North Sea
Computed M2 Tidal Currents North Sea
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
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...
Study of Tides, Setup and Bottom Friction in a Shallow Semi-Enclosed Basin. Part II：Tidal Model and Comparison with Data
Tides Setup Bottom Friction Shallow Semi-Enclosed Basin
2009/2/11
This is the second in a series of papers reporting the results of a study of tides, setup and bottom friction in the Bight of Abace, Bahamas. The extensive field data reported in Part I of the series ...
Open Ocean Modeling as an Inverse Problem：Tidal Theory
Open Ocean Modeling Inverse Problem Tidal Theory
2009/2/8
Classical models of tides in open coastal regions employ ad hoc conditions on the open boundaries instead of reliable sea level data on the coastline in order to achieve a well-posed problem. A weight...
The Generation of Diurnal Period Shelf Waves by Tidal Currents
Diurnal Period Shelf Waves Tidal Currents
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, ...
