Effects of Sediment-Induced Density Gradients on the Estuarine ...

Moreover, two effects of the vertical SedDG are identified to be responsible for sediment trapping: One by enhancing the vertical sediment concentration ...

Density fronts: Sieves in the estuarine sediment transfer system?

Sharply defined water density gradients (due principally to salinity contrasts but also to temperature effects) and velocity gradients occur both ...

Sediment‐Induced Stratification in an Estuarine Bottom Boundary ...

SSC gradients lead to density gradients because SSC is coupled to the fluid density through an equation of state. The result of this coupling is sediment ...
