Research ArticleOpen accessPhrase in the titleAdsorption of Nickel and Zinc by Residual SoilsNur ’Aishah Zarime, W. Y. Wan Zuhairi, Sivarama KrishnaSoil has long been utilized as low cost liner material to prevent contamination from leachate to groundwater media. To find a suitable soil material for this purpose is a great challenge. This study describes the potential use of residual soil to functions as engineered clay liner for waste disposal landfill in Malaysia. Three types of residual soils were investigated namely … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 5 Dec 2014 · 7,116 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleCharacterization and Geotechnical Properties of Penang Residual Soils with Emphasis on LandslidesFauziah Ahmad, Ahmad Shukri Yahaya, Mohd Ahmadullah FarooqiThe predominantly hilly terrain of Penang Island combined with average maximum daily temperatures ranging between 27-35°C and peak rainfall as high as 647 cm makes the overall area potentially susceptible to landslips. Over the recent past construction industry has shown a rapid growth mainly due to increase in the inflow of international tourists and other economic reasons. Eventually, the magnitude … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 8,230 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEvaluation, Selection and Assessment of Guidelines for Chemical Stabilization of Tropical Residual SoilsBujang B.K. Huat, Asmidar Alias, Azlan Abdul AzizSoil stabilization has been widely used as an alternative to substitute the lacking of suitable materials on site. Guidelines and standards have been developed to assist practitioners in designing structures such as road by mean of stabilization. This paper presents the results of an investigation aimed at evaluating and assessing the suitable guidelines for the stabilization of tropical residual soils. … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,652 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleField and Laboratory Suction- Soil Moisture Relationship of Unsaturated Residual SoilsBujang B.K. Huat, Faisal H. Ali, A. AbdullahSoils located above the groundwater table such as residual soils are generally unsaturated and possess negative pore-water pressures. A soil-water (moisture) characteristic curve (SWCC) that relates the water content of a soil to matric suction is an important relationship for the unsaturated soil mechanics. The SWCC essentially shows the ability of an unsaturated soil to retain water under various matric … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,038 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Study on Suction-rainfall Response of a Cut Slope in Unsaturated Residual Soil Using a Field Rain SimulatorBujang B.K. Huat, Faisal Hj. Ali, S. MariappanThis research describes the design and construction of an artificial rain simulator system and the results obtained with regards to suction-rainfall response of a cut slope in unsaturated residual soil of weathered sandstone of various weathering grades. From the field measurements, the shallow tensiometers are found to record an immediate initial increase in matric suction within the first 20 min … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,271 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasuring Hydraulic Conductivity Using Geotechnical CentrifugeNur Aishah Zarime, Wan Zuhairi Wan YaacobThis study investigated the validity of hydraulic conductivity value using Mini Column Infiltration Test. Granitic residual soils from Broga Selangor, Malaysia were tested to obtain the hydraulic conductivity value in relatively shorter time. Soil samples were physically characterized before being tested using Centrifuge Mini Column Infiltration Technique. A normal 1-g Falling Head Permeability Test (Kf) was also being performed as … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 6 Nov 2017 · 7,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATION OF THE GROUNDWATER SUITABILITY FOR IRRIGATION PRACTICES IN AN ARID REGION: CASE STUDYAhmed MuradGroundwater is an important source of acceptable water for irrigation in the arid regions and in particular in the United Arab Emirates (UAE). Demand for groundwater is increasing in the UAE due to population growth and significant economic advancement associated with political stability. As agricultural practices are the main land use in Al Hayer area, southeast UAE, majority of extracted … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 25 Jan 2014 · 7,425 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Oil Contamination on Geotechnical Properties of Basaltic Residual SoilZulfahmi Ali Rahman, Umar Hamzah, Mohd. Raihan Taha et al.Problem statement: Oil contamination due to accidental spillage or leakage brings hefty damage to the environments. It percolates steadily into subsurface environments and contaminates the soil and water system. Hydrocarbon contamination has not just affected the quality of the soil but will also alter the physical properties of oil-contaminated soil. Approach: This study presented the geotechnical properties of oil-contaminated soils … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 10,265 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhenanthrene Contaminated Soil Biotreatment Using Slurry Phase BioreactorM. Arbabi, M. Sadeghi, Ch. AnyakoraProblem Statement: Polycyclic Aromatic Hydrocarbons (PAHs) are suspected toxins that accumulate in soils and sediments due to their insolubility in water and lack of volatility. Slurry-phase biological treatment is one of the innovative technologies that involve the controlled treatment of excavated soil in a bioreactor. Due to highly soil contamination from petroleum compounds in crude oil extraction and also oil … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,758 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrength and Ductility of Randomly Distributed Palm Fibers Reinforced Silty-Sand SoilsS.M. Marandi, M.H. Bagheripour, R. Rahgozar, H. ZareThis paper investigates the resultant strength and ductility behavior when randomly distributed palm fibers are used to reinforce silty-sand soils. The composite soils were tested under laboratory conditions and examined for unconfined compression strength (UCS), California Bearing Ratio (CBR) and compaction test. The results indicated that; the maximum and residual strengths, orientation of surface failures, ductility and the stress-strain relationship … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 8,857 accessesView PDFCite
