  • Assessing the Effects of Motor Oil, Gypsum, and Sodium Chloride on the Behavior of Lime-improved Grey High Plasticity Clay
    Hamid Gadouri, Brahim Meziani
    Periodica Polytechnica Civil Engineering, 2026
    This study evaluates the effects of motor oil (MO), gypsum (CaSO4·2H2O), and sodium chloride (NaCl) as additives on the geotechnical properties of Grey High Plasticity Clay (GS) improved with 0, 4, and 8% lime (L). Each additive was incorporated into GS at 0, 2, and 4% by dry weight. Unconfined compressive strength (UCS) tests were performed on specimens compacted at their optimum moisture content (OMC) and maximum dry density (MDD) after 7, 30, and 120 days of curing. Results indicated that the plasticity index (PI) of GS decreased with the addition of additives, whether used alone or combined with lime. The introduction of any additive into natural or lime-improved GS enhanced soil classification, with gypsum and NaCl exhibiting a more pronounced effect. Additionally, MDD decreased while OMC increased as lime content rose, due to cation exchange reactions leading to clay particle flocculation. However, MDD increased with higher additive contents, whereas OMC decreased with increasing MO and NaCl but rose with gypsum. UCS values improved significantly with any additive, particularly after 120 days of curing. Microstructural analysis via scanning electron microscopy (SEM) revealed the formation of cementitious compounds and/or ettringite in GS samples improved with lime alone or in combination with gypsum, contributing to strength enhancement.
  • Effect of CaCl2 on the Behavior of Lime-Pozzolana-stabilized Marley Soil
    and Hamid Gadouri
    Jordan Journal of Civil Engineering, 2026
    The geotechnical properties of soils are often influenced by chemical compounds and mineral additives. This study investigates the effects of varying calcium chloride (CaCl2) contents (0% to 6% by weight of dry soil) on the Atterberg limits and classification of Marley soil (MS), stabilized with 8% lime (L), 20% natural pozzolana (NP), and their combination (8%L+20%NP). The research also examines the impact of curing time (1 and 30 days) on the plasticity index (PI) and soil classification, both with and without CaCl2. In the absence of CaCl2, the addition of L, alone or combined with NP, significantly reduced the PI of stabilized MS and markedly improved its classification, particularly with the L-NP combination over longer curing periods. In contrast, NP alone caused only a slight decrease in the PI. The inclusion of CaCl2 further reduced the PI in the MS‒L and MS‒L-NP mixtures. Notably, the transformation in soil classification was more substantial with L and L-NP than with NP alone. A comparative evaluation of the Unified Soil Classification System (USCS) and the British Soil Classification System (BSCS) revealed that the BSCS offered greater precision in classifying stabilized MS, underscoring its suitability for such applications. These findings highlight the significant benefits of incorporating CaCl2, alone or in combination with L or L-NP, in enhancing the PI and the classification of MS. The improvements in both PI and classification are influenced by several factors, including additive type and amount, CaCl₂ content, curing period, and the classification system employed. Keywords: Marley soil (MS), Mineral additives (L and NP), Calcium chloride (CaCl2), Atterberg limits, USCS and BSCS classification systems, Stabilization.
  • Flood Risk Assessment in Khemis Miliana, Algeria: An Integrated Modeling Approach
    Brahim Meziani, Hamid Gadouri
    Advances in Transdisciplinary Engineering, 2025
    This study develops an integrated hydrological and hydraulic model for the Oued Souffay watershed, located in the region of Khemis Miliana, Algeria. The primary objective is to assess flood risks and propose effective mitigation strategies for this vulnerable area. The methodology combines geospatial analysis in ArcGIS with specialized modeling software: HEC-HMS (Hydrologic Modeling System) for simulating rainfall-runoff processes and HEC-RAS (River Analysis System) for one-dimensional steady-flow water surface profile computations. Key steps included watershed delineation and morphometric analysis using a Digital Elevation Model (DEM), preparation of geometric data for the river channel (including centerlines, banks, flow paths, and cross-sections) using the HEC-GeoRAS extension, and subsequent import and refinement of this data within HEC-RAS. Manning’s roughness coefficients were carefully assigned based on land cover. The simulation shows how flood areas can be overlaid for a certain weather event. It helps find the places in Khemis Miliana that are at high risk. The study says using HEC-HMS, HEC-RAS, and ArcGIS together is a good way to manage flood zones. It also points out that flooding can hurt infrastructure. So, we need things like better drainage, soil reinforcement, and retention basins to make the city stronger against floods.
  • Assessing the Slope Stability Risk Using LEM: Case Study of the Kouala Landslide in Medea Region, Algeria
    Hamid Gadouri, Brahim Meziani, Ilyes Selami
    Advances in Transdisciplinary Engineering, 2025
    This research examines slope instability at the Kouala site in Medea (northern Algeria), where clear signs of ground movement have already been observed. To quantify the degree of risk, the Limit Equilibrium Method (LEM) was applied, integrating both geotechnical and hydrological parameters such as cohesion, internal friction angle, plasticity index, unit weight, rainfall infiltration, and groundwater level. The simulations reveal that prolonged or intense rainfall reduces the shear strength of marl formations and lowers the factor of safety below the acceptable threshold. The most critical sector is the upper slope, where values fall under 1.0 in saturated conditions, indicating a high probability of rotational sliding. Although the deeper layers are comparatively more resistant, they remain vulnerable to infiltration over time. Thematic maps of cohesion, friction angle, and slope gradient emphasize strong spatial contrasts, with almost 70% of the slope classified as highly to very highly susceptible. These findings confirm the urgent need for stabilization strategies, including drainage control and soil treatment techniques, particularly chemical stabilization with and without reinforcement.

  • Analyzing Landslides Through Geotechnical and Geophysical Surveys: A Case Study the Landslide of the Toll Station in the Djebahia Region of Bouira, Algeria
    Brahim Meziani, Hamid Gadouri
    Advances in Transdisciplinary Engineering, 2023
    This paper focuses on assessing natural hazards in northern Algeria, particularly landslides, earthquakes, and floods, which result in substantial material and human losses. The specific objective of this study is to investigate landslides in the Djebahia region, specifically related to the water transfer pipeline from the Acerdoune dam to M’sila town. The research collects and analyzes geophysical and geotechnical data to identify the key factors influencing landslides in this area.The study reveals that the main factors contributing to induced landslides in Djebahia are the steepness of the terrain, water availability, and soil composition, particularly marl and clay. These factors can lead to varying depths of the sliding surface, ranging from 7 to 20 meters. To mitigate the risk of movement in this region, the paper suggests the installation of two series of piles. Additionally, inclinometers have been placed near these piles to monitor depth-related movements. Over a two-year period, the inclinometric results indicate acceptable displacements at various depths.

  • Geotechnical characterisation and back analysis of a landslide in marl deposit: A case study of Algiers Sahel (coast), Algeria
    M Filali, A Nechnech, J de Rosa, H Gadouri, B Meziani
    Journal of the South African Institution of Civil Engineering, 2020
    The purposeof this study isto present the results of geotechnical investigations and landslide analysis in a marl deposit at the Sahel (coast) of Algiers in northern Algeria, where many landslides take place in the Plaisancian marls, particularly following rainfall periods each year, causing severe damage to infrastructures and buildings. The physico-mechanical characteristics of the soils obtained from three different sites (El-Achour, Daly-Brahim and Ouled-Fayet) were analysed to identify the mechanism of these landslides. In the study, the laboratory test results providing grain-size distribution, Atterberg limits, water content, shear strength, and compressibility were analysed. The findings showed that, although the soils were characterised by slightly higher plasticity at Ouled-Fayet, they were generally homogeneous in the studied sites. The upper soils, generally weathered, exhibited low shear strength parameters, which are lower than the undisturbed formation beneath. The stability analysis based on limit equilibrium methods (LEM) showed the significant influence of pore water pressures on slope stability, suggesting that the weathered soils are prone to instability processes due to the effect of long rainy periods.
