Abstract

This paper deals with the problem of non-equilibrium states in the channel process; their frequent occurence is observed and, therefore, the term of ‘the steady-nonequilibrium states in the river channel formations’ is introduced. The simple typification of non-equilibrity source areas (sources) and the identifying characteristics of the non-equilibrium processes are being discussed.

The methods for non-equilibrity detection and the variants of forecast for the changes in the hydraulico-morphological channel data for the non-equilibrium states of river sections.

Keywords: the non-equilibrium process; the channel process; the non-equilibrium source; the water consumption; the discharge rating curves; the river channel; the floodplain; irregular accumulative forms; quasi-regular channel forms
