ABSTRACT:
Apparatus and method are provided for regulating shoreline change in cases where the magnitude of the longshore transport rate varies along a shoreline and is subject to periodic reversals. The method operates by selectively restricting the longshore sediment transport in one of the two possible shore-parallel directions. Some versions of the directional groin operate by changing the effective height of a low profile structure, while in others segments of the structure are selectively opened or restricted to sediment transport. The transport-obstructing portions of the groin may be positioned by flowing water, or may be moved by an electromechanical actuator acting under control of a microprocessor-based control system that also measures the direction of water flow.
