On the tectonic control of the drainage network pattern in Byelorussia

Abstract

Studies of spatial distribution of river and gullies revealed a certain tectonic control over the drainage network. River valleys of higher order are proved to be associated with subsided elements of the basement, with fault-lines of zones of contact between structures and blocks, sources of low order rivers are situated at neotectonic uplifts. Gullies formation is also typical for positive structures. An examination of fluvial erosion and debris transport directions permits to outline about 50 positive and negative blocks which undergo uplift or subsidence.
