The effects of flocculation on the entrainment of fluid mud layer

Evaluation of the Role of Silt Content on the Flocculation Behavior of Clay‐Silt Mixtures

“…These may have a significant impact on coastal morphology and hydrodynamics and thus influence ecosystems in coastal, riverine, and oceanic environments (Cuthbertson et al., 2010; Guo et al., 2017, 2018; Hu et al., 2020; Pan et al., 2022). In addition, its effect on sediment siltation, water turbidity and quality, and management and maintenance of navigation channels and harbor basins cannot be ignored (Ferguson & Church, 2004; Winterwerp, 2002; Xu et al., 2020; Zhu et al., 2014).…”

“…The added cohesion from clay sediment causes individual particles in a water column to stick together to form aggregates or flocs, which are very fragile (Guo et al., 2017; Mietta et al., 2009; Wang et al., 2018). Flocculation of natural mud has a great potential to alter flocs with sizes, densities, and shapes (and thus settling velocity) that are vastly different from original constitutive primary particles (Berlamont et al., 1993; Ducoste, 2002; Maggi, 2005), which will further influence sediment transport processes, including floc deposition or settling, sediment consolidation or perturbation, and erosion or initiation (Tran et al., 2018; Xu et al., 2020; Xu & Dong, 2017). These may have a significant impact on coastal morphology and hydrodynamics and thus influence ecosystems in coastal, riverine, and oceanic environments (Cuthbertson et al., 2010; Guo et al., 2017, 2018; Hu et al., 2020; Pan et al., 2022).…”

Influence of 2‐hydroxypropyltrimethyl ammonium chloride chitosan on sedimentation and volume change behavior of cohesive soil sediments

“…However, the sedimentation‐dewatering process is time‐consuming and difficult. Similar problems exist in waterways dredging and coastal engineering 20 …”

“…Similar problems exist in waterways dredging and coastal engineering. 20 Many researchers have studied treatment techniques for clay slurry, which is a significant challenge in soil problems. The sedimentation behavior of different soils with different pH and salinity solutions was continually reported.…”
