Application of laser anemometry for measuring critical bed shear stress of sediment core samples

Sediment resuspension mechanisms and their contributions to high‐turbidity events in a large lake

“…The lack of consolidation and presence of cohesive material between the non‐cohesive material may explain the proposed relationship in Fig. a (e.g., Araújo et al ; Mier and Garcia ), because τ cr required to lift the sediments has to be sufficiently strong (increasing ϴ cr ) to overcome the cohesive forces.…”

Erosion of glacial till from the St. Clair River (Great Lakes basin)

“…More recently, Araujo et al (2008) tested cohesive sediment samples in a small circular flume. Velocity profiles were measured with a laser Doppler velocimetry (LDV) system, similar to the one presented in this work.…”

Numerical modelling of tsunami propagation with implications for sedimentation in ancient epicontinental seas: The Lower Jurassic Laurasian Seaway

“…The range of bed shear stress values required to entrain cohesive sediments is more difficult to generalise as it depends on parameters such as grain size, sand to mud ratio, water content, mineralogical composition and even biological activity in the bed. Whilst flocculation means that muds typically have a higher critical threshold bed shear stress than the finest sands, various studies have shown that they usually have threshold values ≪0.5 Nm − 2 (Whitehouse et al, 2000;Araújo et al, 2008).…”
