...Megaripples and dunes are assumed to be absent for silt and clay beds. van Rijn 1984c, 1993 has shown that megaripples and dunes are related to the flow depth h and to the flow regime mobility parameter ....

...Historical overviews of the complicated sediment transport and bed roughness problem are given by Graf 1971 , Vanoni 1975 , and Yalin 1977 for the river regime and by Sleath 1984 , Nielsen 1992 , Fredsøe and Deigaard 1992 , Soulsby 1997 , and van Rijn 1993, 2007 for the coastal regime....

...The experimental results of Einstein and Chien 1955 and those of Winterwerp et al. 1990 suggest that the overall roughness is somewhat larger due to the presence of a large sediment load van Rijn 1993 compared to the roughness in a similar clear water flow....

...41 (Van Rijn, 2000a). However, analysis of the field data shows that the wave height distribution was bimodal rather than Rayleigh-distributed. Fig. 4.7.

...The CROSMOR model also uses this approach based on the Van Rijn (1993) method applied to individual waves (wave by wave approach); the high-frequency suspended load transport is included....

...Results of Area models (Van Rijn, 2000a) show that circulation cell effects are absent during storm events, but these circulation effects are rather pronounced at depressions in the inner bar during low tide (ebb) in combination with low-wave energy conditions (offshore wave heights of 1 to 2 m).
