Abstract
In this work a mode parabolic equation method for resonantly interacting modes accounting for the weak elasticity in the bottom is developed. The proposed method is tested numerically. The test calculations carried out for the ASA wedge benchmark prove an excellent agreement with the source images method for sufficiently small values of shear waves speed that are typical for soft sediments of the sea bottom.
