Definition of rip current in English English dictionary: A strong flow of surface water, away from the shore, that returns water from incoming waves; A current formed on the surface of a body of water by the convergence of currents flowing in opposite directions Rip currents are common along coasts where longshore currents move in opposite directions; A strong, rapid, and brief current that flows out to sea, moving perpendicular to the shoreline; A narrow seaward return flow caused by waves breaking in the surf zone and piling up water against the coast This establishes a hydraulic head which, combined with bathymetric irregularities along the coast, causes the narrow seaward flow See Komar (1976); A narrow intense current setting seaward through the surf zone It removes the excess water brought to the zone by the small net mass transport of waves It is fed by long shore currents Rip currents usually occur at points, groins, jetties, etc , of irregular beaches, and at regular intervals along straight, uninterrupted beaches; A strong, narrow surface current that flows rapidly away from the shore, returning the water carried landward by waves. Also called rip tide, tiderip. or riptide Narrow, jetlike stream of water that flows sporadically seaward for several minutes, in a direction perpendicular to a beach. The term riptide is a misnomer because the currents are in no way related to tides. Rip currents form at long coasts that are approached by wave trains that are nearly parallel to the shoreline. In shallow water, normal wave motion displaces the water small distances shoreward with each passing wave. During periods of large waves, water builds up at the beach and cannot escape as longshore currents, which require oblique wave approach. The buildup continues until water can escape by surging for several minutes through a low point in a breaker, creating an undertow that can be dangerous for swimmers; a strong surface current flowing outwards from a shore; A strong surface current of short duration flowing seaward from the SHORE It usually appears as a visible band of agitated water and is the return movement of water piled up on the SHORE by incoming WAVES and wind A rip current consists of three parts: the FEEDER CURRENT flowing parallel to the shore inside the BREAKERS; the NECK, where the FEEDER CURRENTS converge and flow through the breakers in a narrow band or "rip"; and the HEAD, where the current widens and slackens outside the breaker line See Figure 7; A strong water-surface current of short duration flowing seaward from the shore; the return movement of water piled up on the shore by incoming waves and wind It usually appears as a visible band of agitated water; and, with the outward movement concentrated in a limited band, its velocity is increased A rip current is often miscalled a "rip tide" To swimmers, the phenomenon is known as "undertow"; A strong seaward flowing current, that forms part of the horizontal nearshore circulation and can be considered as the return movement of water moved onshore by incoming waves and wind; It is formed by a strong surface water movement, or current, of a short duration that flows seaward from the shore The return flow is piled up onshore by the incoming waves and wind It is localized, of narrow width, and its position relative to the beach can change as the wave condition changes Therefore, the higher the waves, the stronger the current
