The current Polish Water Law requires adjustment and improvement of water quality. The assessment of the status of water is carried out mainly on the basis of biotic, physical and chemical parameters. Question about the quality of hydromorphological parameters does not appear when the state of flowing water is very good, and when it is good and average the result should be consistent with the other valorization. This approach is aimed at evaluating the effects and does not respond to the questions about reasons why good judgment is given for considered reach of the river. The current evaluation doesn’t indicate the stability of the ecosystem or trends the developing the future state. Do not be in such a situation, the useful life of the existing ecosystem or trends which may be in the future. An important element of the valuation is to determine the intensity of fluvial processes in the riverbed, and the possible dynamics of their changes. Hydromorphological pressures cause disturbances of hydrodynamic balance manifested by changes of the channel types, the channel incision and change the composition of the grain size distribution of the bed surface. This article attempts to indexation fluvial processes. The result can be used to accurately assess the current quality and possible changes in the mountain river beds.
