Abstract
This study deals with the behavior of three-dimensional negative buoyant surface jets released on a sloping bottom. Flow visualization and exhaustive thermometry were carried out to investigate the streamwise variations of the flow and spreading characteristics. The jet momently plunges and reattaches on a water surface, then, the great lateral spreading originates both in the surface and bottom layers, immediately before the complete plunging. This behavior is peculiar in the three-dimensional cases and plays an important role to the flow and spreading mechanism.
