Energy losses of a channel flow under conditions of overflow onto a floodplain

  • Published:
Hydrotechnical Construction Aims and scope

Conclusions

  1. 1.

    The main types of interaction of channel and floodplain flows, which are described by the equation of fluid motion with a variable discharge, were distinguished.

  2. 2.

    The effect of overflow onto the floodplain on the energy losses and other characteristics of the channel flow was established.

  3. 3.

    Relations were obtained which can be used on hydraulic calculations of river flows in the range of investigations conducted (under conditions of intersection of the main channel by a “through-going” floodplain flow with angles of turn of the meander 80–106°, (λb/h)sh=0.17–0.68, and λfl[(B−b)/(h−hsh)]>1.0).
