A simplified model for tidal flow in a basin is presented. The model is based on the assumption of a flat water surface oscillating synchronously in the tidal basin. Under this hypothesis the depth‐averaged continuity equation becomes a Poisson equation that can be easily resolved at each instant of the tidal cycle. This formulation, which is particularly valid for small, deep basins, provides a simplified solution of the depth‐integrated shallow water equations and suggests a possible approach to model long‐term morphodynamic evolution of tidal basins. The model is tested in San Diego Bay, California, and the results are briefly discussed.
