Abstract

A comparison has been made between the hydraulic geometry of sand- and gravel-bed rivers, based on data from alluvial rivers around the world. The results indicate a significant difference in hydraulic geometry. On this basis, some diagrams for discrimination of meandering and braided channel patterns have been established. To predict the development of channel patterns under different natural conditions, the pattern discriminator should be searched on the basis of independent or at least semi-independent variables. The relationship between stream power and bed material grain size shows a better result than the discriminator using the slope-discharge relationship
