The studying of coherent structures and structural properties of a turbulence are the following:

• searchs of new frozen integrals and lagrangian invariants in the hydrodynamical models (together with R.Z.Sagdeev, A.V.Tur, V.V.Yanovsky);

• the investigations of nonkolmogorov regimes of strong turbulence both in the usual- and magneto hydrodynamics related to the cases of finite correlation times of fluctuations, the analysis of their characteristics dependence on the external random force strength (together with S.N.Gordienko);

• The analysis of transport processes features conditioned by excitation of nonkolmogorov turbulence(together with S.N.Gordienko, O.G.Chkhetiani);

• The search of possibilities for hydrodynamical drag reduction due to the coherent structures generation in shear flows.
