摘要

The basic properties of the dynamic model of a turbulent jet formed by a deep-water sewage discharge into the stratified environment of coastal regions are considered.The model developed was used to estimate the parameters of a floating-up jet of deep wastewater discharge from Sand Island into the basin of Mamala Bay(Hawaii)depending on the season and discharge operation mode.The estimates of the float-up depths of the jet and the initial dilution of the jet were estimated on the basis of model calculations using experimental data on the vertical profiles of the water temperature and salinity under the actual conditions of stratification in the study region.It is shown that the further propagation of the wastewater jet depends on tidal events and internal waves generated by tides.The appearance of turbulent jets at the sea surface was recorded.The model estimates of the parameters of the wastewater discharge were compared with the results of experimental measurements.Good agreement was found,which indicates that the physical mechanisms of the propagation of turbulent jets in a stratified medium are adequately described by the model.
