tidal+currents

TIDAL CURRENT: when the water goes to the continents coast and away from the continents coast due to the rise and fall of tides.

//**flood tide: when the tidal current goes to the land.**// //**ebb tide: when the tide goes away from the land (into the ocean).**// //**slack water: when there are no tidal currents.**//

Tidal currents are strongest between two adjacent coastal regions that differ in height of the tides. They are smaller in the open ocean. In bays and in coastlines they create their own strong fast currents.

When a river runs off into the ocean through a long bay the tide creates a tidal bore. //**tidal bore: a surge of water that runs upstream.**// It can start off as a large wave that then loses energy as it travels.
