Toward coupling of groundwater drawdown and pumping time in a constant dischargeAbstract Groundwater is considered an essential water resource in arid and semi-arid regions such as Iran. This study used a copula-based approach to analyze the joint frequency of groundwater level and the duration of groundwater pumping with a constant discharge. In particular, this study examines the correlation between the pumping time and groundwater drawdown v... ... hiện toàn bộ

Recent developments in materials used for the removal of metal ions from acid mine drainage
Springer Science and Business Media LLC - Tập 11 - Trang 1-11 - 2021
Acid mine drainage is the reaction of surface water with sub-surface water located on sulfur bearing rocks, resulting in sulfuric acid. These highly acidic conditions result in leaching of non-biodegradeable heavy metals from rock which then accumulate in flora, posing a significant environmental hazard. Hence, reliable, cost effective remediation techniques are continuously sought after by resear...... hiện toàn bộ
Prediction of ground water quality index to assess suitability for drinking purposes using fuzzy rule-based approach
Springer Science and Business Media LLC - Tập 6 - Trang 393-405 - 2014
Groundwater is the most important natural resource for drinking water to many people around the world, especially in rural areas where the supply of treated water is not available. Drinking water resources cannot be optimally used and sustained unless the quality of water is properly assessed. To this end, an attempt has been made to develop a suitable methodology for the assessment of drinking w...... hiện toàn bộ
Contemplations and investigations on green coagulants in treatment of surface water: a critical review
Springer Science and Business Media LLC - Tập 12 - Trang 1-22 - 2022
Coagulation is an essential and easy process to treat water and wastewater and also to adopt for point of use solutions. Coagulants have played a significant role in providing safe and potable water. Nevertheless, the ill effects of chemical coagulants, such as health effects and substantial sludge quantities, cannot be ignored. Under given conditions, the search for alternative coagulants has bee...... hiện toàn bộ
Modeling of batch sorber system: kinetic, mechanistic, and thermodynamic modeling
Springer Science and Business Media LLC - Tập 7 - Trang 3173-3180 - 2016
The present investigation has dealt with the biosorption of copper and zinc ions on the surface of egg-shell particles in the liquid phase. Various rate models were evaluated to elucidate the kinetics of copper and zinc biosorptions, and the results indicated that the pseudo-second-order model was more appropriate than the pseudo-first-order model. The curve of the initial sorption rate versus the...... hiện toàn bộ
Optimization using central composite design (CCD) of response surface methodology (RSM) for biosorption of hexavalent chromium from aqueous media
Springer Science and Business Media LLC - Tập 10 - Trang 1-12 - 2020
In this study, unmodified biosorbent was obtained from Arachis hypogea husk and applied to remove hexavalent chromium [Cr(VI)] from aqueous media through batch technique. The independent variables (contact time, pH of the solution and initial Cr(VI) concentration) influencing the adsorption process were optimized by central composite design (CCD) found in response surface methodology of the Design...... hiện toàn bộ
A survey on microbial quality and antibiotic resistance in Karoon River, Khuzestan, Iran
Springer Science and Business Media LLC - Tập 8 - Trang 1-6 - 2018
Karoon River is the most important river in Iran that supplies the drinking and industrial water to many cities and villages in Khuzestan. As a consequence of hospital and municipal wastewater discharge into this river, antibiotic resistance will be increased in microbial inhabitants of this ecosystem. Furthermore, microbial load is also undergone continual variation. The aim of this study was to ...... hiện toàn bộ
Rainfall detection over northern Algeria by combining MSG and TRMM data
Springer Science and Business Media LLC - Tập 6 - Trang 1-10 - 2014
In this paper, a new method
to delineate rain areas in northern Algeria is presented. The proposed approach is based on the blending of the geostationary meteosat second generation (MSG), infrared channel with the low-earth orbiting passive tropical rainfall measuring mission (TRMM). To model the system designed, we use an artificial neural network (ANN). We seek to define a relationships between...... hiện toàn bộ
Prediction of white spot disease susceptibility in shrimps using decision trees based machine learning models
Springer Science and Business Media LLC - Tập 14 - Trang 1-15 - 2023
Recently, the spread of white spot disease in shrimps has a major impact on the aquaculture activity worldwide affecting the economy of the countries, especially South-East Asian countries like Vietnam. This deadly disease in shrimps is caused by the White Spot Syndrome Virus (WSSV). Researchers are trying to understand the spread and control of this disease by doing field and laboratory studies c...... hiện toàn bộ
