On the Relationship Between the Main Parameters of Bed Load Transport

  • Published:
Power Technology and Engineering Aims and scope

Analysis of the existing formulas for the bed load allows identifying two important parameters of the bed load transport: the Froude number and the depth-particle size ratio. This article is devoted to the study of the relationship between these parameters. The study is based on the database of the State Hydrological Institute. The relationship between these parameters with the relationship determination coefficient R2 = 0.93 has been obtained. Based on the four formulas for the bed load transport and the formula for the dune velocity, the hypothesis of the interchangeability of these parameters in calculating the bed load transport has been confirmed. For wide hydraulic conditions, a formula for the mean size of bed sediments, which, under certain hydraulic conditions, are in motion as the bed load, has been obtained (average calculation error is 73%).
