UNIFORM LONGSHORE CURRENT MEASUREMENTS AND CALCULATIONS

Abstract

A description is given of laboratory experiments on uniform longshore currents and the comparison of the data with longshore current profiles predicted by a mathematical model. For the mathematical model it is assumed that longshore current generation takes place between the plunge line and the shoreline (instead of shoreward of the breaker line) and Battjes' (2,3) lateral friction model is applied. Good agreement between theory and laboratory data is achieved with realistic values of the bottom roughness.
