Explicit incipient motion of cohesive and non‐cohesive sediments using simple hydraulics

Existing dimensionless expressions that represent the incipient motion of sediments are based on studies of non‐cohesive sediments. Because of the complex behaviour of cohesive sediments, many simulators also assume non‐cohesiveness when simulating the erosion of cohesive sediments. However, studies show that the critical shear force needed for entrainment is much higher for consolidated cohesive sediments than for similarly sized non‐cohesive...
