Popis: Colloque avec actes et comité de lecture. Internationale.; International audience; The modeling of flow induced by submerged sewer system was carried out within laborarory physical experiment. Results of experiments perfomed at two expeimental facilities (Large Termostratified Tank LTSB (20*4*2 m) and small ltank (1.2*0.5*0.5 m) with saline stratification) are presented. The theoretical model of Fan & Brooks (1969) was verified within the series of experiments in saline pycnocline–type stratification in wide range of parameters. The conditions of scaling modeling were determined on the basis of this model, and laboratory scale modeling with geometrical scale 1:27 was perfomed in LTSB. Excitation of intencive temperature oscillations in the picnocline was observed. They were interpreted as self-sustained oscillations of the buoayant plume.
