It is subject to an increasing demand for water like all the great agglomerations due to the economic and demographic development. The groundwater of region is deteriorating because of the economic development, and the rapid growth of population. This article is devoted to the study of hydrochemistry and processes of mineralization of groundwater in this region. The results of physicochemicals analyses shows the same chemical facies of the chloride and sulphate-calcium and magnesium type, with high mineralization from North-East to South-West to the outlet of Béchar–Kénadsa basin. The determination of the mineralization origin and the main major elements were approached by multivariate statistical treatment and geochemical. This method has identified the main chemical phenomena involved in the acquisition of mineralization of water in this aquifer. These phenomena are main...

The transfer is twodimensional effect of the external environment the hottest to the internal environment of the building through a facade consisting of two walls separated by a layer of air. The structure of the flow and the temperature distribution in the two media and the temperature profile of the surfaces of the front wall are determined based on the simulation results for the temperature difference (Rayleigh number) and the temperature sinusoidal excitation.
