Preprints are manuscripts made publicly available before they have been submitted for formal peer review and publication. They might contain new research findings or data. Preprints can be a draft or final version of an author's research but must not have been accepted for publication at the time of submission.

Numerical simulations of the shallow water equations are used to study the effect
of topographic barriers on the tidal range in estuaries. The results show that the
nonlinear advection terms in the momentum equations play very little role, and that
the interaction between the tide and the topographic barriers is mostly due to the
bottom friction, which is represented by the usual quadratic Chezy law.
