Conclusions

  1. 1.

    Channels composed of cohesive and noncohesive soils have a characteristic form of dynamic stability (especially in permeable soils having coagulation-cementation structural bonds).

  2. 2.

    The distribution of the longitudinal velocity in the vertical characterized by the parameter x=0.17 indicates dynamic stability of a channel composed of both noncohesive and cohesive soils.

  3. 3.

    The hydraulic parameters of dynamically stable channels in noncohesive soils can be determined by Eqs. (7)–(9) and in cohesive by Eqs. (10–(12).
