Abstract: It is becoming increasingly difficult to maintain an anple supply of good quality water for domestic and industrial use and the pollution by wastes produced by these sources further reduce the options available for new supplies of water. The resulting fluid mechanisms instigated in these shallow bodies of water (lakes, rivers and bays) are poorly understood. To improve this situation this paper outlines the principal results which were' obtained during the computer- aided experimental investigations of two important shallow water si tuations; the two-dimensional non-buoyant jet and the circul ar buoyant jet. Non-dimensional maps predicting the location of the different jet centre-lines for both situations are presented. Comparisons are also drawn between the dilution and spreading rates of these shallow water jets and corresponding deep water jets.
