Accurate and reliable groundwater level forecasting\nmodels can help ensure the sustainable use of a\nwatershedââ?¬â?¢s aquifers for urban and rural water supply. In\nthis paper, three time series analysis methods, Holtââ?¬â??Winters\n(HW), integrated time series (ITS), and seasonal autoregressive\nintegrated moving average (SARIMA), are\nexplored to simulate the groundwater level in a coastal\naquifer, China. The monthly groundwater table depth data\ncollected in a long time series from 2000 to 2011 are\nsimulated and compared with those three time series\nmodels. The error criteria are estimated using coefficient of\ndetermination (R2), Nashââ?¬â??Sutcliffe model efficiency coefficient\n(E), and root-mean-squared error. The results indicate\nthat three models are all accurate in reproducing the\nhistorical time series of groundwater levels. The comparisons\nof three models show that HW model is more accurate\nin predicting the groundwater levels than SARIMA\nand ITS models. It is recommended that additional studies\nexplore this proposed method, which can be used in turn to\nfacilitate the development and implementation of more\neffective and sustainable groundwater management\nstrategies....
Ground-water is an essential and vital component of our life support system. The ground water quality of Kodaikanal\r\ntaluk, Tamil Nadu for the period of pre monsoon season in the year of 2012 has been studied to evaluate the suitability of\r\nground water for domestic uses. Totally 17 Groundwater samples were collected from open well and bore well and analyzed for\r\nvarious physical (pH, EC, TDS) and chemical parameters (Na, K, Ca, Mg, HCO3, CO3, SO4 and Cl). It is observed that the quality of\r\ngroundwater is suitable for domestic use in most of the location with respect to World Health Organization (WHO 1984) and\r\nsome of the samples are not suitable for drinking purposes. To understand the water quality, Arc GIS software was used to\r\nprepare a spatial distribution map and identify the suitable and unsuitable zones. Finally, overlay the all spatial maps and find\r\nout the unsuitable zones for drinking purposes....
Levafix yellow CA (LY) is a reactive azo dye widely used in textile industries and its removal from wastewater is difficult due to complex structural properties. This paper deals with a hybrid electrochemical degradation-chemical adsorption approach for the removal of LY from aqueous solution. The dye solution containing sodium chloride (NaCl) electrolyte was first electrolyzed using graphite electrodes, followed by adsorption onto magnesium oxide (MgO) or zinc oxide (ZnO) nanoparticles. MgO was found to be a better adsorbent than ZnO. The progress of dye removal was monitored by CV, UV-VIS spectrophotometry, total organic carbon (TOC) measurements and also by Mass spectral analysis. Almost 100% decolourization was achieved by electrolysis while about 90.3 % TOC removal was achieved through adsorption with MgO nanoparticles....

The model presented in this paper is very simple and easy to use. The water usage in residential area consisting of faculty quarters and students� hostels has been studied. The necessary data have been supplied to the model and the minimum water requirements have been computed for different faculty quarters as well as hostels. The model has been solved using TORA software. This study is very useful in deciding the optimal water requirements/distribution in the different units of the university....
Some physicochemical parameters related to groundwater quality obtained from Thittakudi taluk, Cuddalore district\nof Tamilnadu was investigated for the purpose of drinking. Total 40 groundwater samples were collected from tube wells during\nthe month of February 2014. The groundwater samples analyzed for physical properties and chemical characters such as pH, EC,\nTDS, major cations and major anions were measured using standard procedure. The physical properties values varied from pH\n(6.9 to 8.1), EC (610 ?mho/cm to 3984.38 ?mho/cm) and TDS (502 to 2550). Similarly major ions Ca (48 to 119), Mg (31.6 to\n114), Na (3.7 to 75.7), K (1 to 66.1), HCO3 (162.5 to 420.9), SO4 (0.1 to 11.5), Cl (130.43 to 487.44) and NO3 (5 to 25.1). All\nparameters except pH and EC indicate the unite of Mg/l. All the measured parameters compared with WHO (2014) standard for\ndrinking water quality permissible limit. In this case the study area samples were occurred above and below the limit, which\naffect some anthropogenic activities....
The water pollution source localization is of great significance to water environment protection. In this paper, a study on water\npollution source localization is presented. Firstly, the source detection is discussed. Then, the coarse localization methods and\nthe localization methods based on diffusion models are introduced and analyzed, respectively. In addition, the localization method\nbased on the contour is proposed.The detection and localization methods are compared in experiments finally.The results show that\nthe detection method using hypotheses testing is more stable. The performance of the coarse localization algorithm depends on the\nnodes density.The localization based on the diffusion model can yield precise localization results; however, the results are not stable.\nThe localization method based on the contour is better than the other two localization methods when the concentration contours\nare axisymmetric.Thus, in the water pollution source localization, the detection using hypotheses testing is more preferable in the\nsource detection step. If concentration contours are axisymmetric, the localization method based on the contour is the first option.\nAnd, in case the nodes are dense and there is no explicit diffusion model, the coarse localization algorithm can be used, or else the\nlocalization based on diffusion models is a good choice....
Somebody has rightly defined the energy in his very simple way that energy is the ability to do work, but I must not miss to say here that Energy is the thing on which the wheels of the development of any country depends. As much as the wheels of energy turns, more and more the country will prosper especially the case of India which is the seventh largest country in the world where the population is increasing drastically and thatââ?¬â?¢s why is on the verge of extinction of disappearance of conventional fuels like coal, oil, and natural gas as these resources are very finite and if this will be on use in same manner as in current scenario then will be no more available in the near future. So the better, reliable, alternative of this is the more and more use of Non- conventional sources of energy which proved to be a milestone for the betterment of the society and citizens and by this the concept of mankind, humanity, and sustainable development will be retained. The major sources of Non-conventional energy are: a. solar b. Wind c. Tidal d. Geo-thermal e. Biological Energy. My present paper focuses attention towards not only the Types of energy resources to be used i.e. Non- conventional sources but the Alarming question is ââ?¬Å?How much and way of Producing and Managing Energyââ?¬Â? So we are giving more attention towards the better and better exploitation of Energy through Biological Approach i.e. Use of Bio energy....
Auditory information is widely used throughout the animal kingdom in both terrestrial and aquatic environments. Some marine species are dependent on reefs for adult survival and reproduction, and are known to use reef noise to guide orientation towards suitable habitat. Many others that forage in food-rich inshore waters would, however, benefit from avoiding the high density of predators resident on reefs, but nothing is known about whether acoustic cues are used in this context. By analysing a sample of nearly 700,000 crustaceans, caught during experimental playbacks in light traps in the Great Barrier Reef lagoon, we demonstrate an auditory capability in a broad suite of previously neglected taxa, and provide the first evidence in any marine organisms that reef noise can act as a deterrent. In contrast to the larvae of species that require reef habitat for future success, which showed an attraction to broadcasted reef noise, taxa with a pelagic or nocturnally emergent lifestyle actively avoided it. Our results suggest that a far greater range of invertebrate taxa than previously thought can respond to acoustic cues, emphasising yet further the potential negative impact of globally increasing levels of underwater anthropogenic noise....
Removal of color from aqueous solution by using low cost adsorbent was conducted by batch experiment. The potential of the low cost adsorbent Azadirecta indica leaves (Neem) to remove Methylene Blue from aqueous solution were assessed at room temperature. Laboratory investigation of the potential of Azadirecta indica leaves (Neem) powder to remove methylene blue dye from aqueous solution has been studied. The effects of various experimental parameters, such as pH (3-11), adsorbent dosage (1-12 g/l), contact time (15-240 min) and initial dye concentration were investigated. The results showed that the dye removal increased with increase in the initial concentration of the dye and also increased in amount of biosolid used and initial pH....
Aerobic spherical granules were observed in zeolitic dual-layer intermittent percolating filters treating domestic septic tank effluent. The diameter of the granules ranged from 0.05 to 0.5 mm and when they predominate in the biofilms the mean SVI value was of 54 ml g-1 instead of 232 ml g-1 when they were absent.\r\n Flow behavior in these filters was characterized by the dimensionless Reynolds number. The values obtained (40 less than Re less than 60) were representative of intermediate flow conditions and invalidated the current hypothesis of laminar flow conditions. These values were of the magnitude of those estimated from studies on SBR reactors presenting granular sludge formation.\r\n The possible influence of granular sludge formation on long-term performances and interfacial clogging of intermittent dual-layer percolating filters is also discussed....
