Description :
A suite of 40 morphometric variables has been measured on 57 sections of freely meandering channels from 33 rivers. These objective variables are computed from digitized traces of the channel centerline and include measures of sinuosity, meander wavelength, curvature moments, meander asymmetry, and pattern irregularity. Principal components analysis reveals that morphological variations between freely meandering streams can be resolved into four factors related to meander wavelength, meander irregularity, sinuosity, and large-scale wandering of the meander axis.
