Measurement of shallow water wave direction for longshore sediment transport

  • J. Hardisty
Article

Abstract

Formulae which predict the longshore transport of sand under the action of oblique waves are shown to be very sensitive to the angle of incidence of the waves. A simple, computerized wave recorder and pattern-matching technique is described which measures the angle of incidence by determining the phase difference between signals from a pair of closely spaced sensors. Data from field trials suggest that a resolution of better than 4° is possible with this system, but problems of mixed frequency waves remain in both the longshore transport functions and the field equipment.
