The classical system of shallow-water (Saint--Venant) equations describes long surface waves in an inviscid incompressible fluid of a variable depth. Although shock waves are expected in this quasilinear hyperbolic system for a wide class of initial data, we find a sufficient condition on the initial data that guarantees existence of a global classical solution continued from a local solution. The sufficient conditions can be easily satisfied for the fluid flow propagating in one direction with…

Long surface wave dynamics along a convex bottom

[1] Long linear wave transformation in a basin of varying depth is studied for a case of a convex bottom profile h(x) ∼ x4/3. This bottom geometry provides the “nonreflecting” wave propagation at

Rogue waves in nonlinear hyperbolic systems (shallow-water framework)

The formation of rogue waves is studied in the framework of nonlinear hyperbolic systems with an application to nonlinear shallow-water waves. It is shown that the nonlinearity in the random Riemann

Nonlinear wave run-up in bays of arbitrary cross-section: generalization of the Carrier–Greenspan approach

Abstract We present an exact analytical solution of the nonlinear shallow water theory for wave run-up in inclined channels of arbitrary cross-section, which generalizes previous studies on wave

The Water Waves Problem: Mathematical Analysis and Asymptotics

This monograph provides a comprehensive and self-contained study on the theory of water waves equations, a research area that has been very active in recent years. The vast literature devoted to the

Wave Breaking in the Ostrovsky-Hunter Equation

The Ostrovsky--Hunter equation governs evolution of shallow water waves on a rotating fluid in the limit of small high-frequency dispersion and the method of characteristics specifies the blow-up rate at which the waves break.

Global existence of small-norm solutions in the reduced Ostrovsky equation

We use a novel transformation of the reduced Ostrovsky equation to the integrable Tzitz\'eica equation and prove global existence of small-norm solutions in Sobolev space $H^3(R)$. This scenario is
