Abstract
Almost all studies of surface buoyant jet are treated the spreadings in the case of infinitely deep water bodies. This study aims to be clear the behavior of surface buoyant jet dis-charged on the sloping bottom which is very important case for engineering aspects. The phenomena caused by the interaction between sloping bottom and buoyant jet such as (a) the intrusion of quite thin density wedge along the bottom, (b) unstable vor-tex, (c) generation of internal wave at downstream of unstable vortex, (d) drawing down of density interface due to low pres-sure, are reported and discussed.
