ABSTRACT: This study includes a series of laboratory experiments for investigated
the gravity current of fresh water with density ρ-?ρ, and initial speed u0 upon the free surface of an ambient liquid (salty water) with density ρ at rest in a basin. It’s have been presented to illuminate the dominant flow
and transport phenomena in the presence of river, stream and wetland ecology,
stream corridor restoration, in the case of accidental pollution spills. The
characterized of the local kinematic field, i.e.
the local velocity and vorticity fields, the measurement methods include
particle image velocimetry (PIV) at the water surface using a technique similar
to large scale of particle image velocimetry (LSPIV).
