Abstract

This paper evaluates a number of widely used predictive transport equations and the use of tracers and GPS in the measurement of longshore transport for the validation of such equations. It also addresses the inconsistencies which can sometimes be introduced as a result of these techniques. The analysis shows that most of the equations examined tend to over-predict the expected transport by a factor of 1.5 to 4. The use of tracers on macro-tidal coarse grained beaches is found to be a viable method for obtaining reliable transport rate measurements of which the confidence levels are expected to increase as present day calculation techniques are adapted for use on macro-tidal shingle and mixed beaches. DGPS appears to be an economical way of data collection but needs to be used with the highest possible accuracy level settings if it is to be used in quantifiable sediment transport calculations.
