Making use of the explicit nonlinear formulation derived in this paper and the mild slope equation with weak non-linearity calculations are conducted for wave transformation in the compound shoals.

The Computational Mass Transfer(CMT) model is composed of the basic differential mass transfer equation, closing with auxiliary equations and the appropriate accompanying CFD formulation.

A formulation for the equivalent circuit parameters of the discontinuities with superior convergency is derived by the transverse resonance method with the singular integral equation technique.
