ABSTRACT. – The Horton-Strahler River Order Implementation Relevance within the Analysis of the Almaș Basin. The purpose of the present study/research aims at underlining the importance of the enforcement of the river order within the analysis of the Almaș basin relief. The topic was chosen based on the fact that the hydrographic networks hierarchy offers at the same time quality and quantity information, on the relief evolution tendency and also the chance to compare the Almaș tributary sub-basins ones with the others and also with other basins of the same order belonging to other morphological units. The results thus achieved offer information on the rivers order, the confluence report, the river segments density, the form/shape report. The values corresponding to the previously mentioned index, have led us to formulating the following conclusion: the evolution of the Almaș hydrographic network appears therefore strongly influenced by the lithologic sub-layer, by the presence of brittle rocks, by accentuated fragmentation and by the wide energy of the relief, nevertheless by the presence of the local subsidence area/region of Someș, from Jibou.
