Numerical Modelling of High-frequency Internal Waves Generated by River Discharge in Coastal Ocean

I. Marchevsky, A. Osadchiev, A. Popov

Abstract

A method for numerical simulation of internal waves generation by discharges of small and rapid rivers flowing into a coastal sea is proposed. The method is based on PFEM-2 (Particle Finite Element Method, 2nd version) and utilizes particles to simulate convection as well as transfer salinity. Main simplifying assumptions and the mathematical model are presented for this problem. The numerical scheme is split into predictor (particles motion) and corrector (finite element method solution) steps. The resulting method is expected to be efficient in terms of mesh fineness and length of simulation time.
