The oak forests in Algeria are rich in resources and services, playing an important ecological as well as socioeconomic role. The cork oak (Quercus ilex) is one of the most common species in the Chettaba forest, which occupies an area of 1127 hectares. This study aimed to assess the health of this species. The protocols for the crown condition indicator were placed in 13 plots of 0.09 hectares, randomly...
In context of global change, biodiversity loss poses a serious problem in the Mediterranean basin. In Algeria, degradation problems (logging, deforestation, bush fires and agriculture) affect vegetation. Knowledge of vegetation characteristics is necessary to manage disturbed areas. That is why this study focused on demographic structure of main species of Ouled Bechih forest (Quercus canariensis...
Groundwater is essential for sustainable development and drinking water supply in the Saharan regions. This work aims to assess the quality of water for domestic use and the hydrogeochemical characteristics of the phreatic aquifer of the Ouargla. Forty-two (42) wells capturing the phreatic aquifer are sampled and analyzed. The parameters analyzed are pH, EC, TDS, cations and anions. The water’s potability...
In this study, a novel method is proposed to optimize the reinforced parameters influencing the bearing capacity of a shallow square foundation resting on sandy soil reinforced with geosynthetic. The parameters to be optimized are reinforcement length (L), the number of reinforcement layers (N), the depth of the topmost layer of geosynthetic (U), and the vertical distance between two reinforcement...
