NON REFLECTING BOUNDARY-CONDITIONS FOR A 2-DIMENSIONAL LINEARIZED BAROTROPIC SHALLOW-WATER MODEL

We propose a new method to deal with the open boundary conditions prob lem in a barotropic linearized Shallow-Water model. It uses both the s plitting technique and the newtonian relaxation method. We present the oretical solutions and illustrate with numerical examples the efficien cy of the proposed method: outgoing waves are evacuated without distur bing the flow in the physical domain.
