The present study is focused on morphometric characterization and prioritization of Constantine’s highland catchment, an endorheic semi-arid basin situated in the east of Algeria. It is subdivided into seven sub-catchments. Using digital elevation model (DEM) and Arc GIS tools showed that all of the sub-catchments except the Gareat El Tarf sub-watershed (07–07) had a good permeability, high iniltration, and high groundwater potential, as the geological structure controls the drainage. Yet, drainage density varies from 0.28 km/km 2 for sub-watershed of Chott Beida (07–01) to 0.41 km/ km 2 for the Gareat El Tarf (07–07) sub-watershed. After prioritization of the sub-watershed for soils and groundwater potential, we conclude that a large part of the sub-catchments in the Constantine’s highlands showed high erosive levels of soil and a low groundwater potential.enArticle
