Abstract

THE INTERACTIONS BETWEEN WAVES AND CURRENTS WERE EVALUATED AND THEIR POTENTIAL INFLUENCE ON SEDIMENT TRANSPORT ASSESSED. TO CONSIDER WAVE-CURRENT INTERACTIONS, WAVE AND CURRENT FIELDS WERE INDIVIDUALLY EXAMINE AND THEN COMBINED. FLOW FIELDS WERE EXPLORED USING AN AVAILABLE HYDRODYNAMIC MODEL, THE ENVIRONMENTAL FLUID DYNAMICS CODE (HAMRICK, 1996; JIN ET AL. 2000). THREE FLOW FIELDS WERE CONSIDERED: A STRONG CURRENT (A RIVER), A MODERATE CURRENT (A BAY OR HARBOR), AND A WEAK CURRENT (SMALL LAKE WITH WIND-DRIVEN CIRCULATION). WAVE FIELDS WERE EXPLORED USING SMALL AMPLITUDE (LINEAR) WAVE THEORY. THE COMBINED EFFECT OF WAVE-CURRENT INTERACTIONS WAS EXPLORED USING THE APPROACH OF GRANT AND MADSEN (1979). THESE ANALYSES INDICATE THAT, IN THE PRESENCE OF CURRENTS, WAVES DRAMATICALLY ENHANCE SEDIMENT TRANSPORT. EVEN WHEN A CURRENT IS WEAK, THE COMBINED EFFECT OF WAVES AND CURRENTS CAN RESUSPEND AND TRANSPORT SEDIMENTS. FOR THE CONDITIONS EXPLORED, BOTTOM SHEAR STRESSES FROM WAVE-CURRENT INTERACTION WERE GREATER THAN THE SHEAR STRESSES FROM CURRENTS ALONE BY AN ORDER OF MAGNITUDE OR MORE.
