Research ArticleOpen accessIn the abstractCOUPLED NITROGEN AND OXYGEN ISOTOPE STUDY OF NITRATE AT A RURAL UNLINED LANDFILL IN WESTERN VICTORIA, AUSTRALIAJohn W. Moreau, Andrew M. MinardUnderstanding of site-scale physical and chemical heterogeneities will inform remediation strategies for unlined rural landfills worldwide. The aim of this study was to characterize potential sources of nitrogen contamination to groundwater at an unlined landfill in rural western Victoria, Australia. Results revealed simultaneously high concentrations of both nitrate and ammonia within several wells, indicative of heterogeneous redox potentials within the … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 30 Jun 2014 · 7,607 accessesView PDFCite
Research ArticleOpen accessIn the abstractClimatic Severity Victims of Upstream Water Piracy Strongly Evidencing Inland Water-depletion Caused Global Warming vis-a-vis CoolingMiah M. Adel, Mahmood R. Hossain, Saiyeeda F. HossainSince the 80’s, the northwestern and the southwestern parts of the tropical Bangladesh located in the downstream Ganges basin have been having summer temperature above 109°F and winter temperature as low as 37°F. Every year people, particularly, the infants die from heat-and cold-related diseases and hospitals become packed-up with the victims of severe climatic condition. The objective of this research … …American Journal of Environmental Sciences, Vol. 10, Issue 2 · 15 Apr 2014 · 7,642 accessesView PDFCite
Research ArticleOpen accessIn the abstractDownstream Ecocide from Upstream Water PiracyMiah Muhammad AdelUpstream India and downstream Bangladesh share more than 50 international rivers. India has set up water diversion constructions in more than 50% of these rivers, the largest one being on the Bangladesh’s northwest upon the Ganges River, puts Bangladesh’s Gangetic ecosystem at stake. In some border rivers, India has set up groins on her side of river banks. Also, Indian … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 4 Sep 2012 · 9,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Flow Systems and Their Response to Climate Change: A Need for a Water-System View ApproachJoel J. Carrillo-Rivera, Antonio CardonaProblem statement: The interest in early hydrogeological studies was the aquifer unit, as it is the physical media that stores and permits groundwater transfers from the recharge zone to the discharge zone, making groundwater available to boreholes for water extraction. Approach: Recently, the aquifer concept has been complemented by the groundwater flow system theory, where groundwater may be defined by … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 7 Apr 2012 · 8,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractEcological Sanitation in Morocco Promotion of the Urine-Diversion Dehydration Toilets-Case of Dayet IfrahYoussef Abarghaz, M. Mustapha Mahi, Mme Christine Werner et al.Problem statement: Most of people in rural areas in Morocco don’t have adequate systems of collection, evacuation and transport of black and gray water. They simply defecate in nature. There is a huge demand, which cannot possibly be met by conventional sanitation systems due to the enormous costs of the pipe network, lack of water and serious environmental drawbacks in … …American Journal of Environmental Sciences, Vol. 8, Issue 3 · 7 Apr 2012 · 8,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Soil and Water Assessment Tools Model for Runoff EstimationM. Hosseini, M.S.M. Amin, A.M. Ghafouri, M.R. TabatabaeiProblem statement: The most of the distributed or physically-based hydrologic and water quality models from developed countries are not directly applicable in developing countries due to both lack of data and different climatic conditions. Hence, there is a need for a study to be conducted a catchment of developed countries. Approach: From a review of various models to estimate runoff … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,516 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater Resources Management in Various Scenarios Using Numerical ModelS. Askari Marnani, M. Chitsazan, Y. Mirzaei, B. JahandidehProblem statement: Iran is an arid country and only small percent of its water demand is met by rainfall. At present, about 55% of Iran's water being supplied by aquifers and 45% from surface water. Population growth, joint with economic development and rapid growth in industry and farming, has caused a vast increase in demand for water in Iran. But … …Current Research in Geoscience, Vol. 1, Issue 1 · 30 Jun 2010 · 13,769 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation 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 PDFCite
Research ArticleOpen accessIn the abstractImpact of Earthquake Demolition Debris on the Quality of GroundwaterM. S. Benmenni, K. BenrachediProblem statement: Debris from construction or demolition/deconstruction processes have no significant impact on the environment as they are res-usable and inert. This has been also long admitted for solid waste generated by the demolition of damaged cities following violent earthquakes. Approach: This study is a contribution to the assessment of actual impact on the quality of groundwater of buried demolition … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 7,236 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Modeling of Groundwater Flow in Karst Aquifer, Makeng Mining AreaF. M. Rani, Z. H. ChenProblem statement: Making iron ore is one of the largest mining projects in south east of china. Due to the development of mining activities in that site, it has become necessary to increase the depth of exploration. Increase the exploration depth makes the mining tunnels subjected to the karst water inrush. Approach: A hydrological and a hydrogeological model for the … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,467 accessesView PDFCite
