Numerical solutions of the Korteweg–de Vries (KdV) and extended Korteweg–de Vries (eKdV) equations are used to model the transformation of a sinusoidal internal tide as it propagates across the continental shelf. The ocean is idealized as being a two-layer fluid. justified by the fact that most of the oceanic internal wave signal is contained in the gravest mode. The model... https://storeanimalwiz.shop/product-category/gravel/
