A NUMERICAL MODEL OF NEARSHORE CURRENTS DUE TO IRREGULAR WAVES

Solute Dispersion in the Nearshore Due to Oblique Waves

Radar Measurement of Waves and Currents in the Nearshore Zone

The objectives of this effort are to determine the extent to which Doppler radar techniques can be exploited for both qualitative and quantitative nearshore measurement applications. Of particular interest are estimates of surf zone location, extent, surface currents, and wave parameters. To date, optical (video) techniques have been the primary remote sensing technology for these applications....

Numerical and Empirical Investigation of Flow Separation Phenomenon around Semi-buried Pipelines due to Steady Currents

In this paper, in order to understand the flow-pipe interaction more clearly, the variations on flow pattern around semi-buried pipelines due to steady current have physically and numerically been investigated. In physical modeling section, the experiments have been carried out in a flume with 10 meter length, 0.3 meter width and 0.5 meter depth using a P.V.C pipe with 6.35 cm in diameter (for ...

Drag forces on vegetation due to waves and currents

The research focused on the variation trend of drag coefficient with Keulegan-Carpenter number in vegetation mimics in pure wave and combined current-wave flow conditions. Experiments were carried out in the Environmental Fluid Mechanics Laboratory at Delft university of Technology. Completion of this thesis was only made possible with the help of many people who graciously shared their time, e...

Numerical Simulation of Random Irregular Waves for Wave Generation in Laboratory Flumes

Understanding of wave hydrodynamics and its effects are important for engineers and scientists. Important insights may be gained from laboratory studies.  Often the waves are simulated in laboratory flumes do not have the full characteristics of real sea waves. It is then necessary to present reliable methods of wave generation in wave flumes.  In this paper, the results of numerically simulate...
