Research ArticleOpen accessIn the keywordsAssessing the Environmental Impacts of Urban Growth Using Land Use/Land Cover, Water Quality and Health Indicators: A Case Study of Arequipa, PeruOswaldo Villena Carpio, Brian D. FathProblem statement: This research assesses the direct effects of urban expansion on land cover/use, river flow, water quality and the indirect effects of these variables in the rate of gastrointestinal disease in people in Arequipa, Peru through the combined use of satellite remote sensing and geographic information systems. Approach: It also uses information about demographic changes, hydrologic data and land … …American Journal of Environmental Sciences, Vol. 7, Issue 2 · 26 May 2011 · 8,741 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsApplication 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 PDF Cite

Research ArticleOpen accessIn the abstractAn Integrated Approach to Modelling of Flood Hazards in the Rapidly Growing City of Osogbo, Osun State, NigeriaSuleiman Abdul-Azeez Adegboyega, Oluchi Christiana Onuoha, Komolafe Akinola Adesuji et al.In recent times, the swift and uncoordinated urban expansion in the medium sized city of Osogbo has increasingly encroached on the environmental sensitive areas. This uncoordinated exploitation of the ecological fragile areas for urban development has triggered urban flooding, which poses serious threat to human lives and properties in the city. This study therefore utilized geospatial technologies to generate flood … …Space Science International, Vol. 4, Issue 1 · 8 Jan 2018 · 13,829 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEvaluating Rainwater Harvesting System for School BuildingsManoj K. Jha, Nishant ShahFreshwater is becoming limited as our climate and weather pattern changes. In this study, a rainwater harvesting system was evaluated for collecting and utilizing rainwater for uses in non-potable purposes. Water-Balance was carried out for two design scenarios: Single tank and double tank, for irrigation in all main fields (202,724 ft2). The irrigation demand for the entire field was estimated … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 22 Sep 2015 · 8,909 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFuture Water Budgets and Water Supply Stress under Climate Change and Urbanization in the Upper Neuse River Basin, North Carolina, USAMichelle Tong Sun, Ge Sun, Chong Liu et al.Urbanization and climate change are the two major threats to watersheds and the environment in the United States. It is imperative to understand the sensitivity of hydrologic responses to climate and urbanization across different physiographic regions in order to formulate sound watershed management strategies and policies. This study evaluated a watershed water balance model, Water Supply Stress Index (WaSSI), with … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 30 Jun 2015 · 7,162 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRiver Flow Conditions and Dynamic State Analysis of Pahang RiverMuhamad Barzani Gasim, M. E. Toriman, Mushrifah Idris et al.Pahang River (Sg. Pahang) is the longest river in Peninsular Malaysia. Flood is a common event in Pahang River Basin during wet season which triggered by monsoon season. The hydrodynamic study of Pahang River should be well understood especially when it is a target of northeast monsoon which influenced the Pahang River Basin every year (from November to March). 17 … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 10 Jan 2013 · 8,704 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIn situ Shear Tests of Soil Samples with Grass Roots in Alpine EnvironmentE. Comino, A. DruettaProblem statement: The presence of vegetation increases the soil burden stability along slopes and reduces soil erosion. Its contribution is due to mechanical (reinforcing soil shear resistance) and hydrologic controls on streambank and superficial landslides. This study presented the results carried out from experimental in situ test focused to study the increased shear resistance of soil blocks due to root-reinforcement. … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,259 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordHydrologic Modeling to Evaluate the Impact of Hydraulic Fracturing on Stream Low Flows: Challenges and Opportunities for a Simulation StudySuresh Sharma, Aashish Shrestha, Colleen E. McLean, Scott C. MartinHydraulic fracturing (fracking) has been increasing in the eastern part of Ohio for the last few years leading to the increased stress on water resources, particularly on the hydrological low flows. Yet, evaluation of the various impacts of fracking on stream low flows using appropriate tools is still a challenging issue, even though significant progress has been achieved in recent … …American Journal of Environmental Sciences, Vol. 11, Issue 4 · 7 Aug 2015 · 10,414 accessesView PDF Cite
