Simulating offshore sand waves
Sand waves form a prominent regular pattern in the offshore seabeds of sandy shallow seas and pose a threat to a range of offshore activities. A two-dimensional vertical (2DV) flow and morphological simulation model describing the behaviour of these sand waves has been developed. The simulation model contains the 2DV shallow water equations, with a free water surface and a general bed load form...
متن کاملModelling offshore sand waves
Offshore activities often encounter large scale sand patterns, such as sand waves. Sand waves are offshore bed forms occurring at water depths of 10 to 50 m. Their wavelengths can lead up to 500 m and their heights are typically several metres. Furthermore, sand waves have been shown to migrate, with typical velocities of up to metres per year. These dynamic sand waves decrease the least naviga...
متن کاملModelling offshore sand wave evolution
We present a two-dimensional vertical (2DV) flow and morphological numerical model describing the behaviour of offshore sand waves. The model contains the 2DV shallow water equations, with a free water surface and a general bed load formula. The water movement is coupled to the sediment transport equation by a seabed evolution equation. Using this model, we investigate the evolution of sand wav...
متن کاملMORPHODYNAMIC ANLYSIS OF WIND FACES USING SPATIAL SAND ROSE MODEL IN ZABOL AND ZAHAK REGION, IRAN
The majority of Iran’s area is covered by arid and semiarid climates. In these areas, wind causes more erosion compared to water. Therefore, determination of wind characteristics especially its velocity is very important. One of the simplest methods that can supply researchers with the origin of wind erosion in the shortest time is synthesizing sand rose model and interpretation of aerial photo...
متن کاملA coastal morphodynamic model for cross-shore sediment transport
A numerical model to represent the mechanisms of cross-shore sediment transport induced by wave and storm events has been established. The model consists of three sub-models (wave transformation, morphodynamic movement, and sedimentation) capable of representing the transport and redistribution of four grain sizes over a coastal area. It is designed to simulate the morphological evolution cause...
