Marine Denudation and Tidal Currents

Modeling of tidal currents effect on PersianGulf density using MIKE model

General circulation of Persian Gulf has a cyclonic pattern that affected by tide, wind stress and thermohaline force. Although tidal force is very effective in values of current speed, but thermohaline force is dominant in long time because tidal forcing has a short period and returning nature. Tide and density parameters are important in navigating and shipping, especially when ships approachi...

Prediction and Analysis of Tides and Tidal Currents

An efficient algorithm of tidal harmonic analysis and prediction is presented in this paper. The analysis is strengthened by utilising known relationships between tidal constituents found at a neighbouring reference site. The system of linear equations of the least-squares solution is enhanced with included constraint equations. In the case of inadequate data, ill-conditioning in the system of ...

Tidal currents of global tidal models tested using estimates from ocean acoustic tomography

High-resolution frequency determination of tidal components in coastal currents

The ability to resolve closely spaced frequencies of two high-resolution AR spectral methods, the Burg's and Marple's approaches, is examined by using time series of coastal currents measured in waters of Canary Islands. We emphasise their usefulness to resolve tidal harmonic components with close frequencies and low frequency components.

Cross-shore suspended sediment transport under tidal currents

The transport of sediment over an intertidal mudflat by a cross-shore tidal current is investigated analytically by formulating a mathematical model of the fluid and particulate motion. The model exploits the low gradient of the intertidal flats and is based upon a shallow-layer approximation. It is found that the sediment transport comprises advection with the mean flow, deposition and erosion...
