Description :
It is demonstrated that suspended and bed loads differently influence upon the kinematics of the transporting medium. This may be explained by the different mechanism of vertical motion of particles| the motion of suspended load is governed by turbulence of the transporting flow, while for the bed load turbulence is not a determining factor. A scheme is suggested for the energy transformation in the near-bed area of the turbulence flow which is transporting saltation load. In conformity with the above scheme, a part of energy of the averaged fluid stream may be transformed into energy of turbulent pulsations of its velocity by the mechanism of saltation motion of load. Results from experiments which support this consideration are given. (Ed.).
