Abstract: | Consideration is given to a model of turbulent flow in a roughness layer; the model is formed by the equations for turbulent
momentum and turbulence-energy density and by free boundary conditions at self-establishing boundaries of the turbulent zone
in the entire layer and in roughness cells. The model describes the interactions of the flow with the elements of roughness
and the processes in the cells of different scales. Certain calculated characteristics of turbulence in vegetation are given.
