Abstract

The present paper investigates the problem in question with regard to engineering measures on navigable rivers. Carrying out such measures leads to a change in the characteristics of the riverbed stream and its stability parameters. Criteria for ensuring riverbed stability in the conditions of anthropogenic impact on the environment are formed on the basis of investigations carried out.

It examines questions of the hydromorphology of riverbeds exposed to anthropogenic factors. Given the general transport orientation of the study, the main attention is focused on questions connected with ensuring navigable conditions on inland waterways and with extraction of non-metallic building materials from riverbed quarries. These kinds of activity have exerted and continue to exert considerable influence on the riverbed process of navigable rivers. In addition to that, the circle of water users on water facilities is sufficiently wide, and measures carried out by these users also affect the characteristics of the stream and the riverbed. Therefore the composition of users in the classification is not limited to the framework of water transport structures.
