The Principle and Application of Sediment Effective Power

Abstract

The concept of potential velocity is introduced in this paper to explain the principle of sediment effective power. The writer suggests a method to formulate this principle. On this basis, a new classification of moving sediment in an open channel is suggested and a description of the applications to river sedimentation is presented. The variation of von Karman constant in sediment‐laden flow, the distinction between wash load and bed‐material load, as well as the adequacy of sediment transportation formulas are reviewed.
