Computation of reservoir storage capacity and submergence using GIS(Surveying and Land Information Science)
(Ritesh Vijay, Apurba Gupta and Sukumar Devotta,65,4,255-258,Year : 2005)
|
Measurement of volumes is an important task in many civil engineering projects. In designing dams, the volumes that need to be determined are storage and submergence. In this paper, a GIS-based algorithm has been developed to compute storage capacities and submergence scenarios of reservoirs with varying dam height. The computation is based on a digital elevation model (DEM) of the topography and triangulated irregular networks (TIN). The method requires that real-world coordinates are used for the computations, which highlights the need for surveying.

Identification and leaching characteristics of sludge generated from metal pickling and electroplating industries by Toxicity Characteristics Leaching Procedure (TCLP)(Environmental Monitoring and Assessment)
(Ritesh Vijay and T. A. Sihorwala,84,3,193-202,Year : 2003)
|
One of India's major concerns is the increasing level of land pollution largely due to the uncontrolled disposal of industrialsolid and hazardous waste. With rapid industrialization, thegeneration of industrial solid and hazardous waste has increasedappreciably and the nature of waste generated has become complex.Their impacts on the ecological bodies are noticeable. The article describes the details of studies conducted using Toxicity Characteristics Leaching Procedure, to estimate the toxicity effects of the metals viz., chromium, zinc, manganese,iron, nickel, cobalt and copper by the Zero Headspace Extractorfor the sludges generated from effluent treatment plant of steeltube, wire and plating industries on environment constituentslike groundwater, surface water and land. Toxicity Characteristics Leaching Procedure determines the mobility of organic and inorganic analytes of liquid, solid or multiphase waste from hazardous solid wastes in the form of primary and secondary extracts. These extracts are mixed in equal volumeproportion and analyzed by Direct Reading 2000 spectrophotometer.The amount of heavy metals observed during the studies in theleachates were found and the results were compared with HazardousWaste categories as per Indian Standards, TCLP regulatory limitsgiven by United States Environment Protection Agency (USEPA) andGermany Leachate Quality Standards and it was observed that theywere on higher side, needing a proper preventive concept of sludge management including handling, treatment, recovery and disposal.

Bioremediation of Soil Contaminated with Organic Compounds with special reference to Acrylonitirle(Annali di Chimica)
(Deshkar A, Dharmorikar N, Godbole S, Krishnamurthi K, Sarvanadevi S, Vijay Ritesh, Kaul S & Chakrabarti ,93,9-10,729-737,Year : 2003)
|
Enrichment of acrylonitrile (AN) degrading bacterial culture from contaminated soil resulted in the isolation of two cultures which were identified as gram negative small rods (C1) and gram positive cocci (C2). One of the cultures (C1) was identified as Citrobacter fruendii on the basis of biochemical and physiological tests. Both the cultures (C1 and C2) were able to utilize acrylonitrile up to a concentration of 2000 mg/l as the sole source of carbon and nitrogen. The studies also confirmed that the acrylonitrile contaminated soil when ploughed with well mixed AN degrading culture, diammonium phosphate and farmyard manure, could be completely remediated within two months from the date of soil amendment.

Evaluation of noise barriers based on geometries and materials: A review (Environmental Science and Pollution Research)
(Chaitanya Thakre, Vijaya Laxmi, Ritesh Vijay,Accepted ,,,Year : 2021)
|
The acoustical properties of a barrier are highly dependent on the physical properties of the material and the internal structure of the material. The acoustical material can curtail the quality of sound or enhance the dispersion, depends on the application being considered. The efficient acoustic performance of noise barriers possessing different shapes and materials including waste materials are reviewed for field implementation to achieve the low-cost sustainable noise barrier application in the Indian context. The review analysis of research papers demonstrates that the acoustic performance of barriers is dependent on different shapes, materials, textures as well as onsite geometry.? Based on the review study, T-shaped barriers with a soft top surface are found to be efficient at noise attenuation. For transparent barriers, perceived loudness and noise annoyance are assessed lower than that for opaque barriers and utilization of waste materials viz. plastic, rubber, bottom coal ash etc. gives high noise attenuation along with low-cost efficiency. Noise pollution levels are high from prescribed noise limits in most of the Indian metropolitan cities. The Indian government is working on mitigation strategies of noise pollution as well as abiding laws regarding noise standards for the zone (residential, industrial, commercial and silences) wise. In contrast, some communities which are adjacent to roads are suffering from high noise levels in the ambience. Therefore, it requires a coherent strategy for long term measures intended at minimizing exposure of noise hence providing much more comfortable to live, work, and shop near high-traffic roads. Noise barriers are highly beneficial in mitigating the emitted noise from the traffic.??

Droughts are most severe among all natural calamities across the world and spread over larger spatial extent than floods and earthquake. Maharashtra state in India experiences droughts almost every year in one or other part. This study attempts to understand the characteristics of drought during the twentieth century over different districts in Maharashtra, using 113 years (1901?2013) of rainfall data. The deviation of seasonal rainfall for each district has been computed for the identification of drought and its characteristics. The major purpose of this study is to investigate the variation in drought characteristics across the state of Maharashtra over the period of 113 years which may be helpful to deal with the impacts of drought in future and in framing suitable preparedness measures. The analysis revealed that Hingoli, Latur, Ahmednagar, Jalna, Osmanabad, Solapur, Beed, and Parbhani districts are more prone to the frequent and severe drought events with return period of 4?5 years. The change in return period of droughts has been checked for three different eras, i.e., 1901?1950, 1951?2013, and 1981?2013 and it was found that during the period of 1981?2013, drought became more frequent and severe across the state. The maximum rainfall deficiency in the state was observed to be in the range of 43?73%. The long-term data analysis of rainfall revealed that 1918, 1920, 1971, 1987, and 2001 were the years of severe droughts in Maharashtra. Also major parts of the state faced maximum persistency of 2 years. Drought events never persisted in Nagpur. Pune, Hingoli, and Sangli have faced the drought with maximum persistency of 4 years. The findings from the analysis in this study shall be very useful for making regional- and district-level strategies for the effective mitigation of droughts.

The performance of constructed wetland depends upon the types of constructed wetland, vegetation, applied hydraulic load, and media used in the bed. This paper describes the review of constructed wetland on type, technology and treatment of various types of wastewater generated such as textile waste, dairy waste, industrial waste, piggery waste, tannery waste, petrochemical waste, municipal waste, etc. The review summarizes the types of constructed wetlands considering media, vegetation, removal efficiency, construction cost, maintenance cost and land area requirement using life cycle cost analysis. The review compares how and why constructed wetland is a better option as per treatment efficiency, their payback period and cost-effective with the other wastewater treatment technologies. Further, there is no proper guidelines for the selection of media and vegetation in the constructed wetland. It is found that??

An investigation on the predictability of thunderstorms over Kolkata, India using fuzzy inference system and graph connectivity(Natural Hazards)
(Chaudhari S, Das D, Middey A.,76,,63-81,Year : 2015)
|
The purpose of this study was to develop a computing system (CS) with fuzzy membership and graph connectivity approach to estimate the predictability of thunderstorms during the pre-monsoon season (April–May) over Kolkata (22°32′N, 88°20′E), India. The stability indices are taken to form the inputs of the CS. Ten important stability indices are selected to prepare the input of the fuzzy set. The data analysis during the period from 1997 to 2006 led to identify the ranges of the stability indices through membership function for preparing the fuzzy inputs. The possibility of thunderstorms with the given ranges of the stability indices is validated with the bipartite graph connectivity method. The bipartite graphs are prepared with two sets of vertices, one set for three membership functions (strong, moderate and weak) with the stability indices and the other set includes the three membership functions for the probability of thunderstorms (high, medium and low). The percentages of degree of vertex (ΔG) are computed from a sample set of bipartite graph on thunderstorm days and are assigned as the measure of the likelihood of thunderstorms. The results obtained from graph connectivity analysis are found to be in conformity with the output of fuzzy interface system (FIS). The result reveals that the skill of graph connectivity is better and supports the FIS in estimating the predictability of thunderstorms over Kolkata during the pre-monsoon season. The result further reveals from the minimum degree of vertex connectivity that among the ten selected stability indices, only four indices: lifted index, bulk Richardson number, Boyden index and convective available potential energy, are most relevant for estimating the predictability of thunderstorms over Kolkata, India.

"Evaluation of the costs and benefits of Mumbai sewage disposal project India "(Indian Journal of Geo-marine Sciences)
(Leena Vachasiddha,Vol. 46(8),,1539- 1545,Year : 2017)
|
Municipal Corporation of Greater Mumbai intends to undertake Mumbai Sewage Disposal (MSDP) for improvement of environment in and around Mumbai city. Sewage generated from the city currently gets into nearby marine water body. This paper addresses the cost benefit analysis of MSDP works for better compliance of sewage treatment and disposal. Cost benefit analysis indicates that the investment in sewage treatment is economically beneficial and will provide immense social, environmental and economic benefits. Positive benefits such as improved tourism, avoided health costs and enhanced fish catches can be a major outcome of the project. The total capital cost of the project is estimated to be about INR 51510 million and operation and maintenance cost is about INR 2240.6 million. The cost benefit analysis indicates that a benefit of about 25855 million per year due to implementation of this project. The direct cost benefits alone indicate the positive result which is expected due to this project implementation.

Book Chapter- Worldwide business model-environmental and financial aspects. (Submitted and accepted)(Current Developments in Biotechnology & Bioengineering: Waste Treatment Processes for Energy Generation.)
(,,,,Year : 2018)
|
Waste-to-Energy is emerging as an attractive business option due to huge quantities of waste being generated today. Landfilling is now being viewed as environmentally unfavourable because it contributes to GHG emissions and also requires huge areas of land, which may not be possible in small countries or countries with high densities of population. Moreover, large fractions of waste generated have huge energy potential which might get lost if sent to landfill. Waste-to-Energy business is still in its early stages in many parts of the world and the business models are yet to be optimised for successful option. In this chapter, business models practised in various parts of the world in Waste-to-Energy business have been explored and both their financial and environmental aspects have been dealt with. The drivers of such businesses and the problems associated with them have been studied using examples of practices in various countries. One major conclusion is that there is a huge potential of revenue through energy generation from waste but most of the countries suffer from poor waste management practices and little or no incentives to establish such businesses. There exist a variety of models which can be implemented both in poor countries such as those of Africa and rich countries such as those of Europe. Government regulations, laws, incentives and support are highly important to the growth of Waste-to-Energy businesses and play a major role in choosing the right kind of business model. The best business model for a particular region should be designed considering these factors as well as the environmental impacts.

Hexabromocyclododecane in the environment –Issues and Challenges(Indian Journal of Environmental Protection)
(Z.V.P. Murthy ,234-253,,,Year : 2010)
|
The brominated flame retardant, hexabromocyclododecane (HBCD) is extensively used in Europe, and to smaller extent in India, has become of increasing concern to scientists over the past decade. HBCD is not produced in India and the current industrial use-is moderate. Possible emission sources of this chemical in India were identified through a systematic analysis of the use in a life cycle perspective. The information on the environmental concentrations of HBCD is scarce. Environmental studies conducted primarily in Europe, Japan and North America indicates that HBCDs are ubiquitous in sediment and biota. The levels of HBCD seem to be increasing and several trends indicate that this increase may be rapid. The relatively high concentrations detected in herring and foodstuffs provide evidence for bioaccumulation of HBCD. The presence of HBCD in remote background air implies that HBCD has potential for long-range atmospheric transport. The occurrence of high concentrations of HBCD may be sufficient to elicit adverse effects in some wildlife. There is also concern that levels of HBCD could cause adverse effects in sensitive human populations, such as young children, indigenous peoples, and fish consumers. However, our knowledge about these chemicals, their sources, environmental behaviour, and toxicity is limited, making risk assessment difficult. In this paper, the current state of knowledge about HBCD is reviewed and areas for further research recommended for improving future monitoring and risk assessment efforts.

On the biosorption, by brown seaweed, Lobophora variegata, of Ni(II) from aqueous solutions: Equilibrium and thermodynamic studies(Biodegradation)
(Bhavanath Jha and Santlal Jaiswar,661–680,,,Year : 2010)
|
The biosorption equilibrium isotherms of Ni(II) onto marine brown algae Lobophora variegata, which was chemically-modified by CaCl(2) were studied and modeled. To predict the biosorption isotherms and to determine the characteristic parameters for process design, twenty-three one-, two-, three-, four- and five-parameter isotherm models were applied to experimental data. The interaction among biosorbed molecules is attractive and biosorption is carried out on energetically different sites and is an endothermic process. The five-parameter Fritz-Schluender model gives the most accurate fit with high regression coefficient, R (2) (0.9911-0.9975) and F-ratio (118.03-179.96), and low standard error, SE (0.0902-0.0.1556) and the residual or sum of square error, SSE (0.0012-0.1789) values to all experimental data in comparison to other models. The biosorption isotherm models fitted the experimental data in the order: Fritz-Schluender (five-parameter) > Freundlich (two-parameter) > Langmuir (two-parameter) > Khan (three-parameter) > Fritz-Schluender (four-parameter). The thermodynamic parameters such as DeltaG (0), DeltaH (0) and DeltaS (0) have been determined, which indicates the sorption of Ni(II) onto L. variegata was spontaneous and endothermic in nature.
