Sequential leaches (sequential extractions) experiment of 62 elements were carried out for assessing the mobility of contaminated heavy metals and metalloids contaminated in natural sediments; river sediments of Oued El Harrach (Algeria) and lagoon sediments of Bizerte (Tunisia), North African Mediterranean coast. Applied extractants for the sequential leaches are: (A) distilled water for extra...

This paper presents and discusses the results of the project named “Jasmin” implemented in Algiers (Algeria) to control the strong odours of the river named Oued El Harrach, one of the largest rivers in the centre of the city, which is polluted with raw sewage and industrial effluents. Pending the achievement of curative solutions, a temporary option for mitigation nuisance odour by masking age...

The Loukkos basin located in northern Morocco is characterized by developed agriculture and a significant water demand. needs are mainly satisfied from the Oued El Makhazine dam on River. This impacted silting up of its reservoir large amount not valued discharged into sea. aim this study to develop an approach secure supply promote optimal use resources, using decision-making tool RIBASIM. inc...

Solar energy is one of the most important sources renewable energies, which widely used in many fields, such as electricity production through direct superheated steam based on Linear Fresnel Reflector. This study aims to show optical and thermal behavior linear solar reflectors field directed El-Oued region at Algeria. Four days different weather data have been selected track change performanc...

In order to refine the geological mapping and improve our knowledge of Tlemcen Mountains structure (northwestern Algeria), interpretation aeromagnetic data using several processing techniques allowed us map Paleozoic basement Rhar Roubane sedimentary cover constituted by formations Mesozoic Cenozoic age. Structurally, are formed structures (e.g., Sebdou Graben), separated three major transverse...
