Abstract

The interaction of pipe and soil under hydrodynamic flow becomes one of the concern in coastal engineering. Scoured seabed beneath sub-marine pipeline could develop the pipe instability and affect to its safety. The pressure difference between upstream and downstream of pipe will induce a seepage flow in the seabed underneath the pipe. When the velocity increased then the critical point reached, a mixture of sand and water divert to the gap below the pipe and leading to a large velocities in the gap. It generates a larger shear stress on the bed and increase the amount of sediment transport. Due to the complexity of the scour problem, there are many factors affecting the scour depth. Some of them are the pipe position and the wave angle of attack. This study evaluates the bed morphological evolution around pipeline, performed with variation of pipe positions and wave angles of attack.
