Research ArticleOpen accessIn the abstractNumerical Modeling of Periodic Pumping Tests in Wells Penetrating a Heterogeneous AquiferPeter A. Fokker, Joerg Renner, Francesca VergaThis study investigated how to utilize multiple frequency components of pressure data from periodic pulse tests to estimate the intra-well permeability and compressibility distribution and also the presence of heterogeneities in a real field case. Periodic well testing is a technique in which injection or production pulses of a fluid are applied to a well in a periodic fashion. One … …American Journal of Environmental Sciences, Vol. 9, Issue 1 · 13 Jan 2013 · 7,990 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization, Concentrations and Emission Rates of Volatile Organic Compounds from Two Major Landfill Sites in KuwaitMohammad AlAhmad, Marwan Dimashki, Abdallah Nassour, Michael NellesProblem statement: The emission of pollutants from landfill sites in Kuwait is of major concern due to the associated adverse environmental and health impacts. There are 18 landfill sites in Kuwait which are contributing to the emission of atmospheric pollutants including; methane, carbon dioxide and Volatile Organic Compounds (VOCs). Approach: Determine the concentration and composition of VOCs in LFG emissions … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 17 Feb 2012 · 7,976 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecifying Processes: Application to Electrical Power DistributionSabah Al-Fedaghi, Lina Al-SalehProblem statement: This study deals with the problem of how to specify processes. Many process specification methodologies have been determined to be incomplete; for example, ISO 9000:2005 defines process as transforming media inputs into outputs. Nevertheless, the author of the Quality Systems Handbook, declares that such a definition is incomplete because processes create results and not necessarily by transforming inputs. … …Journal of Computer Science, Vol. 7, Issue 11 · 6 Sep 2011 · 6,662 accessesView PDFCite
Research ArticleOpen accessIn the abstractRole of Evaporation in Degrading the "Oil Lakes"Al Rashed Ahamad, Colin BarkerProblem statement: Oil Spills are degraded by aerobic bacteria, water washing, evaporation and oxidation. In the absence of water the first two of these processes cannot operate. This is the situation in the low rainfall environment of the Kuwaiti desert where oil lakes still persist 20 years after the initial spills. The oils contain longer chain n-alkanes but have lost … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 6,747 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Cost Effective and User Friendly Approach to Design Wireline Formation TestsClara Bertolini, Giuseppe Tripaldi, Elena Manassero et al.Problem statement: Wireline formation testing (also named Mini-DSTs) are gaining more and more popularity as a possible alternative to conventional well testing especially where there are major environmental and economical constraints. The increased offshore exploration activity, which often implies highly risky and huge operational costs, makes the conventional well testing less attractive in favor of other technologies that can provide … …American Journal of Environmental Sciences, Vol. 5, Issue 6 · 31 Dec 2009 · 6,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Applied Local Wisdom to Manage Water for Developing Riverside Community: A Case Study of the Lam Ta Kong River BasinSurapong Kongsat, Anongrit Kangrang, Kitti Srisa-ArdProblem statement: An integrated water resource management is accepted technique to solve the water resource problems both water shortage and flood plane in order to improve human life. The combination between local wisdom and modern technology by farmer participation is a main part of integrated management. The mentioned techniques had been being applied for human life in the northeast region … …Journal of Social Sciences, Vol. 5, Issue 2 · 30 Jun 2009 · 8,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractContribution to the Study of the Origin of Salinity in Alluvial Aquifer System in the Ain chabro-Hammamet (North-East ALGERIA)K. Seghir, N. KhériciTebessa is located in the Algerian North East. It is characterized by a semi-arid continental climate with an average interannual precipitation of less than 400 mm. It belongs to the Eastern Saharian Atlas field along the Tunisian borders. It is drained by a certain number of the wouady of which Chabro and Bouakous are the most important. The surface area … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,608 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 abstractPetrology and Origin of Ultramfic Xenoliths from North Eastern Jordan VolcanoesHassan Al-Fugha, Mazen AL-AmairehThe distribution of major, minor and trace elements in the Cenozoic alkali basalt from north-eastern Jordan indicates a homogeneous lava flow from a mantle source. These basaltic rocks contain abundant upper mantle xenoliths (spinal lherzolite, harzburgile and olivine- websterite). Theses xenoliths contain olivine, orthopyroxne, clinoporoxene and a few amounts of spinal. Their mineral assemblages, chemistry, texture and major elements abundances … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,013 accessesView PDFCite
