SAND WAVE EVOLUTION IN KANMON ROUTE

Modelling 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...

Non-linear sand wave evolution

Modelling Sand Wave Variation

In this chapter we present a detailed comparison between the Golden Gate sand wave field and the results of the non-linear sand wave model. As the Golden Gate sand waves show large variation in their characteristics and in their environmental physics, this area gives us the opportunity to study sand wave variation between locations, within one well measured, large area. The nonlinear model used...

Wave Evolution in Water Bodies using Turbulent MPS Simulation

Moving Particle Semi-implicit (MPS) which is a meshless and full Lagrangian method is employed to simulate nonlinear hydrodynamic behavior in a wide variety of engineering application including free surface water waves. In the present study, a numerical particle-based model is developed by the authors using MPS method to simulate different wave problems in the coastal waters. In this model flui...

Wave Propagation in Water‐saturated Sand and Grain Contact Physics

Measurements in sandy ocean sediments over a broad range of frequencies show that the sound speed dispersion is significantly greater than that predicted by the Biot-Stoll model with constant coefficients, and the observed sound attenuation does not seem to follow a consistent power law. The observations may be explained in terms of the Biot-Stoll model with frequency-dependent complex frame bu...
