Modeling and experimental research of turbulent jet propagation in the stratified environment of coastal water areas

The results of model calculations and experimental research of turbulent jet propagation in a stratified environment with reference to the Sand Island wastewater outfall (Hawaii) are considered. The jet’s emergence and initial dilution were estimated on the basis of model calculations and experimental data of the stratified environment characteristics in 2003–2004. The reason for the appearance of the bidirectional quasi-isopycnic structure in the waste and ocean water mixing area was clarified, and an analysis of the TS index was carried out. The jet’s features as calculated from the model and obtained from measurements with hydrophysical and hydrooptical instrumentation were found to closely correspond. The effects of the tides and hydrophysical conditions on the waste water’s turbulent jet characteristics (the jet’s floating-up depth level) have been revealed. The outcomes of the study corroborate the efficiency of the model as a tool for research of deep outfall turbulent jet propagation in the stratified environment of coastal water areas.
