Research ArticleOpen accessIn the abstractReservoir Oscillations with Through FlowA.A. KhanThe two-reservoir problem with through flow is a common feature in wastewater treatment plants. The start of the through flow may cause water surface oscillations in the reservoirs and velocity variations in the connecting pipe during the initial unsteady phase that may adversely affect the operation and under certain conditions may cause overtopping of the upstream reservoir. The classical solution … …American Journal of Environmental Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 7,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Chlorophyll-an in a Small Reservoir by Landsat 7 ImageryMaryam Ghashghaie, Kaveh Ostad-Ali-Askari, Saeid EslamianChlorophyll-a (chla) is a source of water pollution. Monitoring the quality of water in reservoirs is necessary to take any action for protecting the water quality. Traditional methods of sampling are usually costly and time consuming. Also they need skillful labors and some areas are out of reach or sampling at those areas is dangerous. Remote sensing technology could solve … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 21 Apr 2018 · 8,330 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermining the Eutrophication State of Ecbatan Reservoir using Carlson IndexMaryam Ghashghaie, Mohammad Reza Serajian Maralan, Kaveh Ostad-Ali-Askari et al.Reservoirs are vital and necessary resources of potable water. Different sectors such as agriculture, industry and fishery are dependent on these resources which need high quality water. Water quality is mainly evaluated using different parameters such as pH, temperature and turbidity which are easily measured. Also there are some more complicated parameters such as eutrophication degree of a water body. … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 19 Apr 2018 · 8,476 accessesView PDFCite
Case ReportOpen accessIn the abstractEvaluation of Seasonal Autoregressive Integrated Moving Average Models for River Flow ForecastingKassahun Birhanu Tadesse, Megersa Olumana Dinka, Tena Alamirew, Semu Ayalew MogesReservoir operation policies cannot be functional in instant decision making without forecasting the future reservoir inflows. For forecasting inflows into reservoirs with only hydrological data is available like Koga irrigation dam, multivariate forecasting models cannot be used to generate accurate river flow information. As a result, an evaluation of univariate Seasonal Autoregressive Integrated Moving Average (SARIMA) models was done for … …American Journal of Environmental Sciences, Vol. 13, Issue 5 · 28 Sep 2017 · 7,891 accessesView PDFCite
InvestigationOpen accessIn the abstractRecovered Gases and Bacteria from the Clostridium Genus as Ecological Condition Indicators of Bottom Sediments of the Eastern Donbass Small RiversRoman Gennad'yevich Trubnik, Yuriy Aleksandrovich Fedorov, Ludmila Anatol'yevna NedosekaThe results of determination of methane, total hydrogen sulfide and sulfite reducing clostridia in bottom sediments of small rivers and reservoirs of the Eastern Donbass are presented. The horizontal and vertical distribution of levels of reduced gases in bottom sediments is analyzed. The ecological condition of the bottom sediments was estimated by the clostridia titer and the methane index. The … …OnLine Journal of Biological Sciences, Vol. 17, Issue 3 · 27 Jul 2017 · 7,105 accessesView PDFCite
Research ArticleOpen accessIn the abstractReconstruction of the Depositional Setting of Tortonian Sediments in the Yowi Field, Shallow Offshore Niger Delta, Using Wireline LogsPrince Suka Momta, Minapuye Isaac OdigiWell logs and ditch-cuttings information was used to study the subsurface of the Yowi oilfields, shallow offshore, in the eastern Niger Delta sedimentary basin. The essence of the study was to determine the gross depositional environments of selected and-bodies. Electrofacies trends from gamma ray log and mineral composition of ditch-cutting samples were used to reconstruct the depositional environments in the … …Current Research in Geoscience, Vol. 6, Issue 1 · 8 Feb 2016 · 7,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Study of the Higher Aquatic Flora of the Middle Don Basin within Rostov RegionMichael M. Sereda, Olga A. Kapralova, Vlada A. Sereda et al.Middle Don basin is recognized as a biodiversity hotspot, characterized by high diversity of vascular terrestrial plants. However, the significance of its freshwater biodiversity is not well understood now. In the given paper we present the results of the investigation of higher aquatic flora of basin streams and reservoirs within the Middle Don, Rostov region. 90 species of 53 genera … …OnLine Journal of Biological Sciences, Vol. 15, Issue 4 · 29 Oct 2015 · 6,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Soil and Water Assessment Tool Model to Estimate Sediment Yield in Kaw LakeD. Alemayehu, R. Srinivasan, P. DaggupatiKaw Lake is one of the reservoirs built by the Army Corps of Engineers in 1976 for the purpose of flood control, recreation, water supply, navigation and fish and wildlife conservation. The Arkansas River flows from Colorado and Kansas before reaching Oklahoma. As it passes through these states, the water carries various kinds of pollutants such as metals from mine … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 16 Dec 2014 · 8,276 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 · 7,648 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 · 9,077 accessesView PDFCite
