TIME AND BED AVERAGED CONCENTRATIONS UNDER WAVES

Jan J. Bosman, Henk J. Steetzel

Abstract


Four types of sediment concentration under waves are discussed: (a) instantaneous, local, (b) time-averaged, local, (c) instantaneous, bed-averaged and (d) time and bed averaged. The first three mentioned are either hard to interpret or difficult to obtain experimentally. The time and bed averaged concentration is discussed in particular, both its interpretation and its measurement. Two features are discussed: the vertical concentration distribution and the bottom concentration.

Keywords
