More Book Details

Description of the Book:

To evaluate hydrodynamics and waves, investigate sediment movement, and alleviate channel shoaling at Port Orford, numerical modeling simulations are conducted under various hydrodynamic and wave conditions, and different configurations of the breakwater. The channel infilling is examined by identifying the sources and pathways of sediment particles deposited in the ports navigation channel. The current fields show the wind driven flow pattern. Extreme winter storms induce stronger longshore current and can have direct impact on the harbor with incident waves propagating from south-southwest. Particle tracking results indicate that the winter transport regime can motivate rapid channel infilling at Port of Port Orford due to the establishment of sustained sediment transport pathways during storms. Wave actions in coastal areas are more likely to enhance the transport of sediment due to wave-induced sediment resuspension
