    A MACROFORM ANALYSIS TO DESCRIBE THE CITY MORPHOLOGICAL COMPACTNESS FACING THE URBAN SPRAWL PHENOMENON CASE OF BEJAIA CITY
    (university of el oued/جامعة الوادي, 2021-05-01) Tebbane Bouktit, K; Alkama, Dj
    Describing the morphological reality of urban areas is essentia l for any the city ’s sustainability project. Through a comparative analysis based on a series of indices and their confrontation according to the multivariate principal component analysis, we have tried to evaluate from the view point of urban sprawl, the morpho logical compactness of the Algerian coastal Bejaia town. The latter is known to be characterised by physical and natural constraints which influence spatial growth and the process of urban development. The main objective of this article is to establi sh the macroforms classification th at constitute Bejaia city. The configuration analysis ’s results of its urban spots have shown an excessive spread of the agglomeration on the Bejaoui coast, which negatively impacts the city’s sustainability.

    VEGETATION AS A TOOL FOR THERMAL REGULATION OF URBAN MICROCLIMATE IN ARID REGIONS
    (university of el oued/جامعة الوادي, 2021-01-01) Badache, H; Alkama, Dj
    The city of Biskra is known by its hot and arid climate; its outdoor spaces know extremely high temperatures during t he s ummer period, which affect thermal comfort, well being, user’s satisfaction in public spaces, such as the "Revolution’s plaza" which known by considerable attendance and a particular design. This study, focuses on the role of the urban vegetation on th e th ermal regulation in the open space. The main purpose is to study the effect of vegetation on the urban microclimate of this space “Revolution plaza”, through a site investigation, in order to measure the local climate and compare the results with weath er’s station data. After that, an improvement case is suggested by simulation by Envi Met 4 software. The results show the significant effect of the trees and natural surfaces in decreasing the heat transfer and temperatures degrees; which provides a favor able microclimate in this open space
