Understanding sediment dynamics and anthropogenic impacts in the land-sea interaction zone of the Abandoned Yellow River Delta is challenged by complex material sources. This study aims to reconstruct sedimentary environment evolution and evaluate human influences on silty-mud tidal flats. Sediment cores were collected from a bare flat (GT) and a Spartina alterniflora marsh (HM) in the Yancheng coastal wetland, Jiangsu, China....

River confluences contribute to the outflux of saturated dissolved gases in the water resulting from high dam discharges. This process is related to gas transfer across the water–air interface, which is primarily controlled by turbulent dissipation near the water surface. However, the near-surface turbulence dissipation is rarely reported in confluence hydrodynamics studies. This study conducted experiments with different disc...
