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 PDFCite
Research ArticleOpen accessIn the abstractSpatial Variability of Irrigation Water Percolation Rates and Its Relation to Rice ProductivityW. Aimrun, M.S.M. Amin, A. GholizadehProblem statement: Study on spatial variability of vertical saturated hydraulic conductivity or percolation loss was conducted within a plot of an area of 1.2 ha paddy plot to find out the relationship between percolation rate and rice productivity. A paddy soil condition that permits percolation rate of 10-20 mm irrigation water day-1 was recommended in order to get high yield … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 8,146 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Grazing Sorghum Stubble on Soil Physical Properties and Subsequent Crop PerformanceB.J. Radford, D.F. Yule, M. Braunack, C. PlayfordTwo grazing trials were conducted on a Vertosol in central Queensland to assess the effects of stubble grazing by cattle on soil properties and subsequent crop performance. Two adjacent contour bays were selected for two treatments (grazed and ungrazed) in each trial. Both trials were conducted following a grain sorghum crop. In trial 1 (during 1996) the surface soil was … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 8,154 accessesView PDFCite
Research ArticleOpen accessIn the abstractVulnerability and Pollution Risks in the Alluvial Aquifer of Tebessa-MorsottS. Kachi, N. Kherici, N. KachiWe studied the vulnerability and risks of pollution of the alluvial aquifer of Tebessa-Morsott that ranks amongst the major groundwater reservoirs of the region. The method used to asses groundwater vulnerability was the DRASTIC method, based on seven parameters that affect and control the groundwater flow: Depth to groundwater, Impact of the unsaturated zone, net recharge, aquifer media, hydraulic conductivity, … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,812 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Assessment and Monitoring of a Permeable Reactive Barrier for the Remediation of a Contaminated SiteValerio Zolla, Rajandrea Sethi, Antonio Di MolfettaThe present study illustrates the long-term monitoring plan carried out in order to investigate the performance of a zero-valent iron permeable reactive barrier (PRB) at a chlorinated solvents’ site. The cleanup intervention has been undertaken at an industrial landfill located near the city of Turin (Italy) and represents the first full-scale application of this technology in Italy. The monitoring plan … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Levan by Bacillus licheniformis for Use as a Soil Sealant in Earthen Manure Storage StructuresAbdel E. Ghaly, F. Arab, N.S. Mahmoud, J. HigginsManure application is not permitted on frozen land in Canada and therefore, manure management and storage are the primary issues facing the agri-food industry. Low-cost, effective and environmentally safe earthen manure storage (EMS) facilities will lower costs and help make the livestock industry more competitive and efficient. The goal of this study was to develop a biological sealing technology for … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,974 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHydrogeological Prognosis with Regard to Realisation of the New Colle Di Tenda Road TunnelCinzia Banzato, Massimo Vincenzo Civita, Adriano Fiorucci et al.Problem statement: The doubling of Tenda pass road tunnel jointing SW France to Piedmont (Italy) was planned to penetrate a complicate rock structure in which several complex play an hydrogeologic role including carbonate-Karst aquifer between flysch impervious complexes. The main problem of the project is the presence of an hydraulic circulation feeding a spring of social and economic great importance … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 7,363 accessesView PDFCite
