Deposition Properties of Fine Sediment

Hydrodynamics and sedimentology of concave benches in a lowland river

“…For flows from benchfull to bankfull the hydrodynamic model replicates flows over the bench with extremely low velocities (V b 0.2 m s − 1 ) and shear stresses (τ b 0.5 N m − 2 ), well below thresholds commonly associated with erosion (Haralampides et al, 2003). Vertical velocities are extremely low throughout the water column (with a slight downward trend).…”

“…Shear stress thresholds are predicated on a number of empirical studies, described in Table 1, and in particular the flume study of Haralampides et al (2003). The representative maximum sediment size diameter is 'medium-sand' (b0.5 mm), as defined by Blott and Pye (2001).…”

The Fine‐Sediment Cascade

“…Thus, the process of flocculation and the transport of fine sediment as flocs and aggregates are clearly fundamental for understanding the dynamics of the fine-sediment cascade. For further details on the transport of cohesive sediment, the reader is referred to the excellent review in Krishnappan (2007) and the applications given in Haralampides, Corquodale and Krishnappan (2003) and Bungartz and Wanner (2004).…”

Developing an expert system for predicting alluvial channel geometry using ANN

“…Yen (2002), Chiu and Tung (2002), and Smart, Duncan, and Walsh (2002) analyzed flow resistance and maximum velocity in open channels. Guo and Jin (2002), Yang and Lim (2003), Abrahams (2003), and Haralampides, McCorquodale, and Krishnappan (2003) studied suspended-load, total-load, and bed-load sediment transport in alluvial streams. Buhman, Gates, and Watson (2002), Simon, Thomas, Curini, and Shields (2002), and Chitale (2003) studied the fluvial hydraulic geometry and channel stability of the Mississippi, Red, and Missouri rivers.…”
