Abstract: The position of a buoynant jet in a lake was investigated by means of in-situ measurements. These measurements at several cross sections enabled the jet axis to be traced, and, as well, enabled determina- tion of the jet intensity, definition of the hori zontal spreading, identification of the jet deflection to the right and recognition of the spreading asymmetry. Morever, it was possible to quantify the jet dilution A spatial representation of the waste water jet recorded by measurements (Figure 5) is compared to results obtained from a mathematical model. The horizontal and vertical spreading of the jet and its dilution agree best with the predicted values. However, the finel layer where the jet levels out seems to be deeper than calculated. The results obtained from a single test cannot, of course, be considered to be representative. Nevertheless the measurements present a coherent picture and consequently confirm buoyant jet theory.
