Tidal bores are a hydraulic phenomenon that is often not well explained and poorly documented. Herein, the writer explains what a tidal bore is, where it occurs, since when it has been observed, how it develops and why the occurrence of a bore has a significant impact on estuarine systems. In particular it is shown that a tidal bore results from a fragile balance between tidal and fluvial conditions, the estuary shape, and the meteorological conditions.
