    Sammanfattning : A modal Perfectly Matched Layer (PML) is constructed for the two-dimensional, non-linear, Shallow Water Equations (SWEs) in conservative variables. The result is an analytical continuation of the original equations where absorption is applied to the outgoing wave modes which are damped exponentially fast in the direction of propagation. LÄS MER
