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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
