Implication

Numerical modeling reveals flocculation influences sediment transport and ecology in wave bottom layers, suggesting improved modeling for better predictions.

Key Points

This research aims to develop a cohesive sediment transport modeling framework that incorporates flocculation effects.
Developed a modeling framework based on a Population Balance Equation (PBE)
Used Direct Numerical Simulation to generate baseline sediment concentration profiles
Analyzed flocculation effects across different sediment concentration conditions
Flocculation significantly influences sediment concentration profiles, leading to distinct stages of sediment structure
At low concentrations, turbulence drives flocculation; as concentration increases, cohesive floc properties become critical
Depth-averaged settling velocity fails to accurately parameterize well-developed lutoclines, requiring enhanced formulations
