    THE USE OF MULTIVARIAT STATISTICAL METHODE TO STUDY THE AQUIFER SYSTEM OF TERMINAL COMPLEX WATER IN THE WADI RIGH VALLEY AREA (SOUTHERN ALGERIA)
    (University of Eloued جامعة الوادي, 2017-09-01) Bettahar, A.; Nezli, I. E.; Kechiched, R.
    Groundwater resources in the wadi Righ valley are presented by two major aquifers: Intercalary Continental and Terminal Complex. From a qualitative point of view, various studies have highlighted that the waters of this region showed excessive mineralization, including the waters of the Terminal Complex (EC = 5854.61 S / cm) .The present article is a statistical approach by two multi methods various complementary (ACP CAH), applied to the analytical data of multilayered aquifer waters Terminal Complex of the Oued Righ valley. The approach is to establish a correlation between the chemical composition of water and the lithological nature of different aquifer levels formations, and predict possible connection between groundwater’s layers. The results show that the mineralization of water is from geological origin. They concern the composition of the layers that make up the Complex Terminal.          Â

    The Use Of Solar Energy In The Desalination Sea Water In Agricultural Greenhouse
    (2010-01-01) Tahri, T.; Bettahar, A.; Douani, M.; Al Sulaiman Abdul-wahab, S.; Al-hinai, H.; Al Mulla, Y.
    The limited resources of fresh water in arid areas like the Middle East and North Africa MENA have led to the use of poor quality water in irrigation agriculture. These can reduce crop yield and environmental damage. Agriculture accounts for 70% of overall consumption in freshwater. Given the evaporation phenomena that occur in arid regions, this figure rises to 90%. This study focuses on the concept of combining the greenhouse with the desalination of seawater This concept is intended for small scale applications in remote areas where only saline water and solar energy are available. The main objective of this research work is to analyze the production of fresh water using solar energy in the desalination of sea water in the greenhouse. This operating system is in need of thorough study of evaporators, condensers and design of the greenhouse. Desalination, combining the greenhouse to the use of sea water while exploiting the phenomenon of condensation of water vapor in the air, seems to respond positively to the needs of agricultural irrigation
