Abstract
Tidal currents over the sill of Knight Inlet, a fjord on the western Canadian coast, are frequently in excess of 1 m · s−2. This shallow sill (65 m) is composed of cobble‐ to boulder‐sized sediments that support extensive growths of large gorgonian corals. Although current‐generated shear stresses are normally far from sufficient to initiate boulder movement, drag forces due to the attached corals do cause a significant rearrangement of the boulders on the sill.This publication has 0 references indexed in Scilit:
