A Lagrangian-Eulerian procedure for the coupled solution of the Navier-Stokes and shallow water equations for landslide-generated waves

Abstract: This work presents a partitioned method for landslide-generated wave events. The proposed strategy combines a Lagrangian Navier Stokes multi-fluid solver with an Eulerian method based on the Boussinesq shallow water equations. The Lagrangian solver uses the Particle Finite Element Method to model the landslide runout, its impact against the water body and the consequent wave generation. The results of this fully-resolved analysis are stored at selected interfaces and then used as input for the shallow water so… Show more

“…The aim of this chapter is to explore the possibilities of coupling the presented shallow water models with the Navier-Stokes equations. In this research, the developments of chapters 3 and 4 are combined with a NS solver, and have been presented in [118]. Having all the formulations within the same framework -FEM and implementation-ease the strategy.…”
