Accurate modelling of instantaneous sediment transport processes in coastal environments has been a great challenge for many decades. One of the difficulties comes from the existence of time lag between flow and sediment transport, termed as “the non-equilibrium transport effect”. To better understand and simulate the sediment transport processes, field observations were conducted on the middle intertidal flats of Jiangsu coast. Water depths, current velocity profiles, wave parameters, stratified suspended sediment concentrations (SSC), as well as grain sizes of both suspended sediment and bed ...
