Abstract
Large scale laboratory measurements of sediment dynamics in the swash zone are presented. Two bichromatic wave group conditions were generated, having the same energy content but different wave group period (Tg = 15.0 s and 27.7s). For the shortest wave group, due to bore focusing, the shoreline fluctuates predominantly at the time scale, showing a large runup and the presence of wave–swash interactions with strong momentum exchange. In contrast, for the longer wave groups, the swash excursion...
