On statistic analysis of longitudinal river profiles applied to morphostructures identification

Abstract

The proposed technique of longitudinal stream profile analysis is based on relation between morphometric characteristics of profile and watershed area. The main criterion of the estimation of stream profile is index of erosional dissection, its value being mainly controlled by stream discharge. The technique of stream profile analysis allows to define the significance of differentiated tectonic movements by the way of successive elimination of such important factors as lithology, water discharge etc.
