applied for the analysis. From the presented analysis it follows that even for the
very broad river, there is an influence of river banks. Practically, the influence
does not disappear. The author is conscious of the fact that the conclusions are
drawn upon the turbulence model applied in the horizontal plane. So the analysis
can be treated as an approach. But the results of experiments presented in the
literature agree with the proposed model.
3. We also analyzed the river bank friction's influence upon the average flow
velocity in the river cross section. In comparison to the velocity that was
calculated by Chezy's formula, this value is smaller by ca. 6% according to
the flow conditions. Every time, this value can be calculated from the formulae
mentioned in this chapter.
4. Further analysis is needed to explain the role of movable bed in the creation of
the eddy viscosity coefficient at the bottom and its influence on the river depth.
