Answer:
A coast with river channels, as well as narrow bays and coves.
Explanation:
Tidal bore is the term used to describe the violent encounter between the waters of a river and the waves of the high tide. Usually this encounter occurs in relation to the phase changes on the moon, mainly between the full and new moons. The result of this is the rise in the level of oceanic waters, which can invade rivers, or form giant waves.
A tidal bore can easily happen on coasts that have river channels, as well as narrow bays and inlets.
