Morphometric elements of the 7th-order hydrographic sub-basins of the Sărățel Stream [articol]

Abstract

The Sărățel Stream is located in the most geodynamic area of the Romanian territory, the Subcarpathian Curvature. The physical-geographical characteristics, as well as the social-human impact, created a specific landscape system, in which the present morphodynamic processes register accentuated dynamics. Uplift and erosion, together with relief are the fundamental components of geomorpho-dynamic systems of the Sărățel catchment. On the other hand, for the geomorphologic characterization of any geographical space we take into account the river morphometric parameters, which can be useful in quantitative morphodynamic studies. Then, using the Horton-Strahler classification system, we obtained for each sub-basin the morphometric model of drainage of the stream segments of successively increasing orders; the laws that define them verify well at the scale of the river sub-basin.
