In coastal oceanography there is interest in problems modeled by the shallow water equations, where variations in channel depth are accounted for by the presence of source terms. A numerical treatment for the solution of such problems is presented here, in terms of a hybrid approach, which combines

โฆ Synopsis
The dynamics of shallow water has been studied and an algorithm for this dynamics has been developed. Results have been obtained with data of the Venice lagoon using a model made expressively by a semi-implicit method based on a ยฎnite element method in space. Comparison has been made between ยฎeld data and the results of the simulation. Very good agreement is shown over a long period of simulation.

A multidimensional discretisation of the shallow water equations governing unsteady free-surface flow is proposed. The method, based on a residual distribution discretisation, relies on a characteristic eigenvector decomposition of each cell residual, and the use of appropriate distribution schemes.
A multigrid semi-implicit ยฎnite difference method is presented to solve the two-dimensional shallow water equations which describe the behaviour of basin water under the inยฏuence of the Coriolis force, atmospheric pressure gradients and tides. The semi-implicit ยฎnite difference method discretizes im
In this paper, adaptive algorithms for time and space discretizations are added to an existing solution method previously applied to the Venice Lagoon Tidal Circulation problem. An analysis of the interactions between space and time discretizations adaptation algorithms is presented. In particular,
A convergence proof is given for an abstract parabolic equation using general space decomposition techniques. The space decomposition technique may be a domain decomposition method, a multilevel method, or a multigrid method. It is shown that if the Euler or Crank-Nicolson scheme is used for the par
