Predicting seabed mobility is hampered by the limited accuracy of sediment transport models when bed composed mixed sediments. The hiding-exposure (HE) effect modifies threshold motion individual grain classes in mixtures and its strength dependent on size distribution. However, an appropriate method predicting this for bimodal remains to be developed. prototypical example a mixture that consisting well-sorted sand gravel fine coarse fractions respectively. Through comprehensive series...
<p>Coarse and bimodal sediment mixtures like sand gravel are common in palaeo-glaciated shelf seas coastal environments. Their presence leads to more complex transport morphodynamic processes, depending on the ratio of bed. With increased pressure our near-and offshore sea beds, there is a growing need accurately model bedform dynamics with an increasing focus sand-gravel mixtures. Revisiting quantification hiding-exposure (HE) effect highlighted how differently sized grains...
