Valley profile analysis for morphostructural studies

Abstract

A longitudinal profile of a valley is discussed which is drawn considering -the river's discharge. Analysis- of such reduced profile makes possible to distinguish the influence of rocks resistance and of differentiated tectonic movements as well as to estimate them quantitatively. 50 tributaries of the Burinda River (the Amur drainage basin) have been analyzed using the described technique and a schematic map of relative block movements have been compiled.
