Abstract
Based on a case study of the Upper Ob (from the confluence of the Biya and Katun rivers to Barnaul), we offer a hydrologo-morphometric characteristic of the point bars, i.e. the sections of the channel that have dried out at a low-water period. We provide a substantiation for their morphological classification; the relationship with riffles of different types has been established. We obtained dependencies of the basic parameters of the point bars (their pitch and width) on hydraulicity of the branches and their relative width which are differentiated with respect to morphologically homogeneous sections and types of riffles.
