This thesis presents the results of an experimental and analytical study of single-port buoyant turbulent jets discharged into shallow water. The experimental results include the measured downstream dilution, centerline concentration and trajectory. Independent parameters considered were Froude number, submerged depth, discharge angle and velocity ratio. Results indicate that decreasing the discharge depth provides earlier occurrence of surface effect and greatly decreases dilution. Dilution increases with decreasing Froude number. Increasing the discharge angle from the horizontal into cross current increases the dilution ratio. The effect of ambient current on dilution depends on the angle of discharge. For cross-flow discharges, the dilution rate decreases with increasing ambient current, while for co-flow discharge the reverse trend was observed. As plumes reach the water surface, the dilution rate increases with increasing ambient velocity. The jets bend over rapidly for cross-flow discharges when large ambient currents are present. The analytical portion of this report presents an integral method proposed by Davis (1975) for merging multiple buoyant jets. This merging model was used to simulate the single-port buoyant jet in shallow water. This was done by using an image method where the submerged depth was simulated by the spacing between images. The entrainment function as presented by Kannberg and Davis (1978) was used except for a modification within the zone of merged plumes. Comparisons of the model prediction were made with experimental data. Results indicate that good predictions are obtained for buoyant jets discharging at 0 and 45 degrees into shallow water by using the image method as long as the Froude number is above 13.5. For lower Froude number and vertical discharges, model predictions are only fair.

The problem of a vertical plane jet-plume in shallow water was investigated experimentally and analytically. The four distinct regions of flow are the jet-plume region, surface impingement region, internal hydraulic jump region and the stratified counterflow region. Only the first three were studied in detail. The experiments concentrated on the surface impingement and internal hydraulic jump regions. Velocity profiles and dye photographs were compiled for six runs. An additional 13 runs were done in which only dye photographs were taken. The velocity profiles and scale.data were then analyzed and plotted. The analytical portion of the study consisted of three parts. The first was the development of the plane jet-plume equations. The second part was a control volume type of analysis of the surface impingement region. This yielded an equation for the impingement depth of the surface layer. The third part was a momentum analysis of the internal hydraulic jump region. Two distinct equations were developed. The experimental data was compared to the predictions of the theoretical equations. The variations of the velocity and length scales were compared to the case of a plane non-buoyant surface discharge.
