In addition to moving water toward and away from shore, tidal currents often cause a parallel flow of water along the shoreline. For example, in waters off Honolulu, Hawai‘i, the rising tide tends …

Tidal currents are defined as the periodic movement of water primarily driven by head differences created by out-of-phase ocean tides, influenced by local weather, ocean characteristics, and …

When tidal currents are directed toward the land, water levels rise in harbors and rivers; these are called flood tides. Tidal currents flowing seaward with falling sea levels are called ebb tides. …
