Densitycurrents generated by saline and fresh water interactions are also important in the transport of sediment in estuaries.
由盐水和淡水相互作用所产生的异重流，在河口泥沙输移中也是很重要的。
2
The density of the gases are low enough to allow convective currents to develop.
气体的密度低到足以形成对流。
3
The contour currents colliding with the overlapped low density normal seawater can create internal waves of large scale at the interface of the thermohaline.
