Popis:	Shallow-water equations in a domain representing a strait are transformed into curvilinear coordinates concordant with the domain configuration and mapping the domain onto a rectangle with two opposite open boundaries. The initial boundary value problem for the equations in the form of contravariant fluxes is considered and compared with a reduced formulation of boundary conditions for equations linearized near the boundary. A method for numerical integration of the transformed boundary value problem is discussed. Particular attention is given to modification ensuring stable computation in the case of strong nonlinearity and variability of domain metric.
