Numerical Modeling of Water Waves Interaction With Soft Mud Beds: Based on an Empirical Rheology Model

Qi Peng,Hou Yijun

Strategic Study of CAE 2006, Volume 8, Issue 4,   Pages 39-45

Abstract:

On the basis of the semi-empirical rheology model of soft mud under such oscillatory external forcesas water waves, a vertical 2-D numerical model is developed for simulating the interaction between surfacewater waves and underlying soft mud beds.A logarithmic grid from the water-mud interface in the vertical direction is employed for numerical treatmentModel verifications are given through comparisons between the calculated and the measured bed mud mass
