Using the Archydro tool for watershed delineationCase of the Kherzet Youcef mine, North-eastern Algeria

Résumé

Abstract This research article is attempted on the study of the morphological characteristics of the oued Loussif sub-watershed, located in the Wilaya of Sétif, Algeria. This study is part of a more general study on the hydrogeological study of the Kherzet Youcef deposit. In all fields interested in the study of spatial phenomena, a need for automation is emerging, especially for geographical structures of the ‘network’ type, given their systemic organization of space that is not explained in databases of geographical data. In order to meet this need for automation, the use of Geographic Information Systems has proven to be cost-effective. Morphological characteristics such as flow accumulation, flow direction and stream network were extracted on the basis of the digital elevation model (DEM), and the results were interpreted and analyzed. The geographic information system (GIS) based approach with the use of DME facilitates the understanding of the different morphological features represented in the thematic matrix data maps, and the correlation between flow accumulations, flow direction, stream order and stream network has been well explored. The study represents the morphological characteristics extracted from the DEM. The software used to perform the global analysis was ESRI ArcGIS version 10.8 with the ESRI Spatial Analyst and ArcHydro extension. Morphological features are effective in understanding the spatial distribution of the watercourse network and identifying potential groundwater locations.
