This study is concerned with basic properties of three-dimensional thermal jumps. Temperature measurements obtained in three-dimensional thermal jumps are presented. The jumps analyzed have identical initial densimetric Froude number (F0 = 7.5), enlargement ratio (β = 5), excess temperature (θ0 = 15°C), and dilution (S = 2.5). The experiment shows that the depth and length of the jump vary with the temperature of the ambient water. The results are compared with a thermal jump theory [Baddour(1992)].
