Vertical distribution characteristics and concentration predictive equation of suspended sediment driven by pneumatic desilting
Localized sediment siltation presents a significant engineering hurdle for critical water-related infrastructure. Recent research addresses this challenge by investigating pneumatic jet desilting technology, identifying four dynamic stages of sediment suspension and quantifying vertical distribution characteristics. A predictive equation for suspended sediment concentration, derived from multiphase kinetic energy dissipation, reveals spatial distribution laws governed by turbulent entrainment and gravity.
Numerical simulation of sediment transport characteristics under tidal action in the Qiantang estuary
Understanding sediment dynamics in high-energy estuaries is critical for effective disaster prevention and resource management. This study introduces a validated, unstructured triangular-mesh numerical model specifically designed to simulate sediment transport within the Qiantang River Estuary (QRE), accounting for density variations and riverbed evolution. Empirical calibration and validation against field data demonstrate reliable representation of hydrodynamic and sedimentary conditions, revealing significant intra-tidal fluctuations and a distinct turbidity maximum zone.
