Mixing and transport. [In surface waters]
A review is presented of various experiments and models developed for predicting mixing and transport in aqueous environments. Some dye studies are reported, for example in the determination of values for longitudinal dispersion, vertical diffusion and lateral diffusion coefficients in the Mississippi River. The thermal response of rivers to variable meteorological conditions and transient thermal discharges and flows was also modeled. For lakes and reservoirs, several numerical modeels for circulation and mixing are described. A discussion of the stratification of deep lakes is given, and one model predicts vertical variations in temperature, phosphorus, nitrogen, oxygen and algae in Lake Washington. Some models are described which predict estuarine flow, while for coastal waters and oceans, a model for mixing because of wave current interactions was developed, and showed that the angle between the surface waves and the coastal currents had an important effect on mixing. In relation to jets and plumes, models for buoyant surface jets and nonbuoyant submerged jets are presented. Acoustic techniques are mentioned for use in tracking the transport and mixing of drifting and settling sewage sludge in coastal waters. The interaction of surface waves and spilled oil was investigated, and a model described for the real-time prediction of oil slick transport and mixing in Delaware Bay.
