Numerical simulation of water waves generation due to deformable granular landslides
Water waves generated by deformable granular landslides in enclosed water bodies are very hazardous.The complicated phenomena occurred in this highly unsteady process are difficult to model because three interacting phases: air, water and deformable granular are involved.Solutions currently available are mostly based on the shallow water approximation.However,neglecting vertical accelerations is inaccurate in the generation zone where depth change rapidly,and on the shore, where run-up and wave-breaking occur.In this work, we modeling the generation of water waves owing to deformable granular landslides by solving the Navier-Stokes equations coupling with the Volume of Fluid (VOF) method tracking of the interfaces between the phases and describing the rheology of the granular landslides using a non-Newtonian fluid model.The comparison between the numerical results and experimental data reported in the literature confirms the accuracy of the proposed method.
