The codification of the rivers network and basins from the Sărăţel morpho-hydrographic system (Buzău)

Abstract

The codification of the fluvial network within the Sărăţel morpho-hydrographic Basin displays the typology approached by Gravelius, a coding system used in the Romanian Waters Cadastre; subsequently, the coding proposed by Pfafstetter is presented, as it is used for large and small rivers as well as for basins and sub-basins. Both systems start the classification from the main course to the smallest rivers. This contribution proposes a new coding system for Sărăţel basin, based on the Horton – Strahler classification, which starts from the small arteries of the first order, to the greatest one, of a superior order, a classification elaborated and used by Zăvoianu et al. (2010). The new system can be adapted to GIS and starts from simple to complex, from small to large, respectively. The new aspect consists in the fast spatial identification of the sub-basins along with the achievement, the development and utilisation of a database created during the codification. The system can be recommended for detailed studies, in small and large hydrographic basins.
