Definitions and Key Parameters
Sediment transport in coastal environments is driven by the combined motions of waves and currents. Due to the orbital nature of wave motion, methods developed for measuring sediment transport in unidirectional flow field may not be directly applicable in measuring coastal sediment transport. Furthermore, wave breaking and associated intense turbulence play a significant role in nearshore sediment transport . In the following, the term nearshore is used in a general sense, representing various coastal environments with shallow water.
Generally, sediment transport rate is calculated as
where x and z = horizontal and vertical coordinates, t = time, x n = width of a certain nearshore zone over which the transport is computed, U s = particle velocity, and C s = sediment...
