Abstract: This paper presents experimental study on the interact ions between two-dimensional surface buoyant jet and bottom slope. Experimental works were conducted using vertically two-dimensional flume at various densimetric Froude numbers and bottom slopes. The important experimental results are summerized as follows. (A) Strong effects of bottom slope: S and densimetric Froude number at outlet: F _ (d0) on the density interface configurations were observed and classified into five types. Classification diagram in S-F do plane was also proposed. (B) Densimetric Froude number of the ultimate flow condi t ion: F _ (df) of three among five types was found F _ (df) =0.50～0.55 regardless of S and F _ (d0). (C) The phenomena of generation of intermittent large scale density waves due to the interactions by bottom slope were observed experimentally. Additional experimental works were also conducted in three-dimensional flume to observe fundamental features of bottom slope effects on the buoyant spreading. Experiments revealed strong effects of bottom slope to lateral spreading but weak effects to surface temperature reduction on jet axies.
