Brief description

Ripple height, length and sediment composition were measured in the nearshore of several low-energy beaches with concurrent measurements of incident waves. The distribution of sediment sizes over individual ripples was investigated, and the performance of several models of ripple geometry prediction was tested both spatially and temporally.
