Abstract

The presence of the even-aged buried alluvial suits in a majority plane and mountain valleys, unified longitudinal profiles of their bottom show that the rivers inherit the present-day position during the whole Quaternary period. It is the valleys of the relative tectonic homogeneous regions which are exposed to inter-valley reconfiguration because feel the strong climate influence as universal factor The regime-water-load drainage and common trend of stream activity – incision and sedimentation are converted under the influence of rhythmic landscape-climate changing The local crustal motion introduce some modification, but don’t destroy the common patterns there. The intra-valley rebuilding of valley is descended at another territories where someone else impact alternate the interior structure and spatial location of valleys. These areas have been controlled mainly by crustal deformation changing the whole structure scheme. The valleys can transform its plane configuration and lose its tributaries. The eustatic sea-level variation influence by repeated modifications to the channel systems on local and regional scales. The coastal areas have been subjected to numerous transgression, many of them extending onto the present land area. In the course of regression the valley system at the continental margin were elongated by many hundred of kilometers, reaching the shelf edge. During transgression many drainage basins were fragmented and new drainage formed at subsequent regressions. The sea level oscillations can produce the valleys reconfiguration as intra- so inter-valley types according to inclination of shelf surface and submarine drift transport processes. At these areas not only drainage reconfiguration but other environmental transformation take place.
