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 PDF Cite

Research ArticleOpen accessIn the abstractClimate Change Adaptation in Acid Sulfate LandscapesChuxia LinOxidation of sulfide minerals produces sulfuric acid and consequently creates Acid Sulfate Landscapes (ASLs), which represent one of the most degraded types of land-surface environments. Although acid sulfate-producing weathering is a naturally occurring process, it is markedly facilitated by human intervention. Mining is by far the dominant anthropogenic cause for the creation of inland acid sulfate footprints while land reclamation … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 7 Jul 2012 · 7,382 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRemoving Boron from an Aqueous Solution Using Turmeric Extract-Aided Coagulation-FlocculationAzhar Abdul Halim, Nur Hanani Thaldiri, Normah Awang, Mohd Talib LatifProblem statement: Boron exists in an environment naturally either through weathering of rocks or volcanic activity but due to anthropogenic activity, boron had been distributed widely into our surroundings. Boron was a problematic pollutant due to the difficulty to remove it from the water. Turmeric which had been widely used as a spice and traditional medicine, were investigated to determine … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 15 Jun 2012 · 8,329 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCollapsibility and Volume Change Behavior of Unsaturated Residual SoilAzlan A. Aziz, Faisal H. Ali, chioong F. heng et al.Residual soils occur in most countries of the world but the greater areas and depths are normally found in tropical humid areas. In these places, the soil forming processes are still very active and the weathering development is much faster than the erosive factor. Most residual soil exhibit high suctions for most of the year. The absence of positive pore … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,121 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA 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 PDF Cite
