Abstract: This paper presents the results ofan experimental study on the near-field diffusion of bluff buoyant turbulent surface jets with small (source) Richardson number in a large body of water without any ambient currents. It has been found that the velocity scale decreases inversely with the axial distance x from the outfall whereas the vertical and surface length scales h and b grow linearly with x. The variation of the coefficients in the relations for these scales, with the source Richardson number has been evaluated using the experimental observations.
