Abstract : An important result of this research is a new model of periodic wavs of finite amplitude, propagating without change of form in shallow water. The model is analytic and deterministic, and it shows good agreement with laboratory experiments. A second important result is the development of a rigorous method to find exponentially small effects, which lie beyond all orders in conventional asymptotic expansion. Keywords: Nonlinear wave motion; Shallow water waves,; Kadomtsev-Petviashvili equation; Asymptotics beyond all orders; Integrable models.
