An integrated mass approach to the measurement of longshore transport is provided to overcome the limitations of the kinematic method. A data set (N-60) for longshore sediment transport at Sandy Hook, New Jersey, USA, developed from a multi-elevational sediment trap, indicates that the transport can be best predicted by the energy flux factor using solitary wave theory with a coefficient of proportionality equal to 0.77. The energetics approach to longshore transport is found to be less accurate unless exceptionally large non-wave driven currents are present The long- term predictive relationship is shown to be nearly exact for the essentially unidirectional oceanside transport system although the instantaneous relationship may be in error by an order of magnitude.
