| description | Developed on the south-eastern side of Almãjului Mountains, Eşelniţa
drainage basin neighbours upon the following basins: upon S – SV with Mala, upon SV - V
with Mraconia, upon V – NV with Berzasca, upon NV - NNE with Nera and on the NNE – SE
direction with Cerna. The basin has a surface of 77 km2 and present a 5th degree hydrographic
network according to Horton-Strahler ranking system, tributary to Danube by means of
Eşelniţa main collector. Developed in a mountain landscape, the basin presents different
levels held between minimum altitude of 64 m at the confluence with the Danube and
maximum altitude of 1107 m, thus presenting a difference of 1043 m. Geological formations
within the basin belong predominant to the Danubian Domain, so in central and upper
courses, these are represented by a crystalline foundation and by magmatic rocks of intrusive
nature covered by very small areas of sediment located in the northwest (belong to the Lower
Jurassic) and in the south-eastern (belongs to the Upper Cretaceous) of the basin. But in the
lower course, there are both crystalline and the sedimentary formations, last being integrated
to Orşova depression and whose presence is related to the evolution of the Danube.
Morphometric indices of Eşelniţa basin allows the distinction of a higher sector, mountainous
terrain with high energy under a relatively increased fragmentation and depression sector
with low relief energy and also with an intense fragmentation of the existing sedimentary
rocks wich favors erosion manifestation in the context of deforestation action. |
