Abstract

This paper illustrates that the flow resistance equations require further testing and development for gravel bed rivers. Such rivers are characterized by coarse bed materials, steeps slopes, and low depths. Comparison of data with the similar resistance equation relating the Darcy -Weisbach friction factor to the logarithm of relative submergence shows that the equation tends to overestimate the resistance in uniform flow. The main objective of this paper is review the current knowledge about flow resistance in gravel bed rivers.
