Abstract

This study aims to be clear the behavior of surface buoyant jet discharged on the sloping bottom which is very important for the engineering aspects. Experimental studies are conducted using veritically two-dimensional flume at various conditions.The classifications of density interface are done and find strong effects by bottom slope : S and densimetric Froude number at outlet : F do. Also, densimetric Froude number of the ultimate flow condition : F 1f is found F 1f0.8 regardless of S and F do.
