INTERACTION BETWEEN TWO CIRCULAR SANDY ISLANDS ON FLAT SHALLOW SEABED OWING TO WAVES

High-Order Interaction of Solitary Waves on Shallow Water

The interaction of solitary waves on shallow water is examined to fourth order. At first order the interaction is governed by the Korteweg–de Vries (KdV) equation, and it is shown that the unidirectional assumption, of right-moving waves only, is incompatible with mass conservation at third order. To resolve this, a mass conserving system of KdV equations, involving both rightand left-moving wa...

Interaction between periodic elastic waves and two contact nonlinearities

Interaction of surface waves with vorticity in shallow water.

Vortical flows in shallow water interact with long surface waves by virtue of the nonlinear terms of the fluid equations. Analytical formulae are derived that quantify the spontaneous generation of such waves by unsteady vorticity as well as the scattering of surface waves by vorticity. In a first Born approximation the radiated surface elevation is linearly related to the Fourier transform of ...

Numerical Analysis of Dynamic Interaction Between Non-Linear Waves and Permeable Toe Over Sand Seabed in Front of a Seawall

A combined BEM-FEM model has been developed to simulate the dynamic interaction between non-linear waves and an impermeable seawall with a submerged rubble toe over a sand seabed. A poro-elastic finite element model has been developed and used under the surface pressure computed by the BEM-FEM model. Modified Navier-Stokes equations are used to solve the flow inside the porous media and Biot's ...

Steel Catenary Riser-Seabed Interaction Due to Caspian Sea Environmental Conditions

This paper investigates the integrated riser/vessel system which is subjected to random waves. Riser pipelines are the main components of the oil and gas offshore platforms. Whereas Iran country has been located on the fringes of Caspian Sea deep water, therefore study and research in this area is increasingly essential. The fluctuation of floating production causes the severe response and grea...
