| tidal force | fuerza de marea |
| tidal marine life | biota marina de la zona litoral |

| tidal mudflat | zona inundable |

| tidal power | energía de las mareas |
| tidal power Mechanical power, which may be converted to electrical power, generated by the rise and fall of ocean tides. The possibilities of utilizing tidal power have been studied for many generations, but the only feasible schemes devised so far are based on the use of one or more tidal basins, separated from the sea by dams (known as barrages), and of hydraulic turbines through which water passes on its way between the basins and the sea | energía de las mareas |
| tidal power station | centrales maremotrices |
| tidal power station Power station where the generation of power is provided by the ebb and flow of the tides. The principle is that water collected at high tide behind a barrage is released at low tide to turn a turbine that, in turn, drives a generator | centrales maremotrices |
| tidal range | carrera de marea |
| tidal water | agua de marea |
| tidal water Any water whose level changes periodically due to tidal action | agua de marea |
| tidal waterways | ríos de mareas |
