Channels and water divides angles of convergence analysis within the Saratov region at the Volga left bank

Abstract

The analysis of angles of channels and erosional landforms convergence as well as those of water divides indicates the angles to be in close relation with the channels and watersheds orders. As the order becomes higher the angles increase from 30-40o (for the 1st order) to 80-90o (for the 6th order and higher). The regularity can be used while reconstructing paleohydrographic network and paleo-watersheds for any buried topographic surface.
