Research ArticleOpen accessIn the keywordsSimulation of Phosphorus Movement in Unconfined Aquifer by Means of Visual MODFLOWSeyed Reza Saghravani, Sa'ari Mustapha, Shaharin Ibrahim et al.Problem statement: In three recent decays, computer software’s are used for assessing and predicting of what happened and what will happen for surface and subsurface water. These supplementary tools are calculating and presenting potential recharge of contamination to estimate and assess important issue in hydrogeology such as amount of contamination in drinking water. There is a source of contamination in … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 7,407 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdvective Heat Transport in an Unconfined Aquifer Induced by the Field Injection of an Open-Loop Groundwater Heat PumpStefano Lo Russo, Glenda TaddiaProblem statement: The increasing diffusion of low-enthalpy geothermal open-loop Groundwater Heat Pumps (GWHP) providing buildings air conditioning requires a careful assessment of the overall effects on groundwater system, especially in the urban areas. The impact on the groundwater temperature in the surrounding area of the re-injection well is directly linked to the aquifer properties. Physical processes affecting heat transport within … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,970 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSimulation of Vegetative Induced Deformation in an Unsaturated SoilNazri Bn Ali, Mu’azu Mohammed AbdullahiProblem statement: Tree root water-uptake increases soil strength by increasing the soil matric suction due to pore pressure dissipation in a soil mass, inducing increases in vertical total stress or water extraction, the effective stress to which the soil strata is subjected to may also increase. This causes volume change which might be detrimental to geotechnical structures and shallow foundation. … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,135 accessesView PDF Cite
