This paper investigates the physical, chemical, and microstructural properties of two types natural sand; alluvial sands dune sand from El-Oued region in northeastern Algerian Sahara. Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), Fluorescence (XRF), Scanning electron microscopy (SEM/EDS), granulometry analysis have been performed. The FTIR XRD prove that consist high ...

Abstract Study region Oued Fez, Morocco. focus Urban catchments are heterogeneous in terms of land use and have both natural artificial drainage networks. Modelling them is not a straightforward task especially data-scarce settings. This study investigates network representation hydrological modelling using field data collected between 2008 2018 on the Fez catchment. The road used as proxy for ...

The northern region of Algeria is experiencing a real threat to the spatial extension soil erosion. Oued Bouhamdane watershed, part this region, brings together all natural and anthropogenic conditions that accelerate its degradation. This study based on use remote sensing GIS map erosion in watershed north-eastern Algeria, using Gavrilovic equation. combination data from different sources fiel...

This work aims to study the distribution and quantification of genus Rhizosolenia known for its abundance diversity among planktonic diatoms at 9 sampling stations in Nador lagoon during 2 seasons (spring summer 2018). The collected were identified morphologically using an inverted optical microscope. A total 10 species have been listed including: bushsolei, R alata forma alata, bergonii, cochl...

Abstract This article reports on a new project to investigate the activities of early Homo sapiens in area Chotts ‘megalake’ southern Tunisia. Excavations 2015 and 2019 at Oued el Akarit revealed one number Middle Stone Age (MSA) horizons near top long sequence Upper Pleistocene deposits. The site identified as ( Sondage 8 ) consists lithic artefacts, bone fragments large ungulates pieces ostri...
