Abstract: The hydrochemistry of the Gajwel, Medak district has been evaluated, as the evaluation of chemistry quality of groundwater is an important aspect in its utilisation. A number of water samples have been analysed in details to classify and to understand the basic character of chemical composition of the groundwater and hydrochemical environment of the area. In order to understand the importance of quality of the groundwater and its suitability for a particular use both qualitaive and quantitative studies have been carried out on the basis of chemical analysis to know the types of water and also composition and concentration of various constituents present in the water in order to establish whether the quality of groundwater of the area is suitable for different purposes. The quality fluctuations and the variations in the concentration of different ions have been identified. Thus, the analytical data has been correlated with different parameters like Wilcox, U. S. Salinity Laboratory, Kelly ' s Index, SAR, TDS, RSC and Piper ' s Trilinear diagram etc. and have been used to classify the basic character of chemical composition of the groundwater. Based on the hydrochemistry, utilitarian aspects of groundwater ' s have been classified into three major divisions viz.,i) domestic / drinking criteria, ii) irrigation / agricultural water criteria and iii) industrial water criteria.

Abstract: The increase in population and urbanization has resulted in the production of huge amount of wastewater . The problems of sewage water disposal can be solved only by effective utilization of this wastewater for agricultural irrigation. But heavy metals like zinc, cadmium, silver, arsenic etc, are present in the sewage. If the untreated sewage water is used for irrigation, the heavy metals directly affect the soil properties and accumulate in the arrigation crops. It directly affects the human health when it is consumed. Therefore, the sewage water can be used for irrigation purposes for the cultivation of non-edible palnts like flowering plants. The present investigation was carried out to find out the irrigational response of sewage water on growth and yield of African mariegold (Togetes errecta L ). Field experiments were conducted with African mariegold by irrigating the sewage water as well as water (control). The various morphological growth parameters such as root length, shoot length, number of branches, number of leaves, total leaf area and their dry weight were recorded at 30,60 and 90 days after sowing (DAS). The yield parameters viz., number of flowers per pant, flower yield, flower diameter and 100 flower weight were recoded at 90 DAS. The study reveals that flowering plants had the greater growth rate and yield in sewage water irrigation when compared to control.

Abstract: Eutrophication is a vital issue in india due to unsafe disposal of domestic wastewater containing Phosphorous (P) in water bodies. On the background use of Constructed Wetlands in U. S. and European countries, it seems to be an attractive option to hinder such pollution. In this context, a pilot unit consisting Typha latifolia and stone grit bed media was studied in a batch mode for P - removal in comparison with reference unit. In this study, the batch CWTS demonstrated 4% to 23% removal during HRT of 1.5 to 7.5 days due to adsorption and plant uptake mechanisms. The Typha pants were found to have uptake of 147.89 kgP/ha.year. The P adsorbed was found to be 0.02 mgP/g stone grit used as bed media during four months of study. The technique may prove to be a viable treatment option option for the treatment of P rich wastewater, with further research related with evaluation of different media and wetland plants for theirn potential application in batch type constructed wetlands.

Abstract: In thermal power stations, surplus heat is produced as a result of energy production. about 15% surplus heat is discarded directly into the atmosphere through the flue gas. The reminder is rejected from the condenser through cooling water leading to physico-chemical and biological cahnges in the surrounding environment. The changes in temperature of receiving water bodies through surplus heat cause adverse impact, which changes the utility and productivity of organisms. The coal fired Thermal Power Station (TPS) releasing huge amounts of fly ash mixed with water into the aquatic environments. This may gradually lead to deterioration of such ecosystem. Discharges of oil from TPS also have adverse impact on aquatic ecosystem. The aim of present study is to discuss the effects of TPS on aquatic ecosystems.

Abstract: Laboratory experiments were conducted to study the effect of different concentrations (5,10,25, 50, and 100%) of textile dye industry effluent on germination and seedling growth of green gram ( Vigna radiata L. Wiczek) varieties. Germination percentage, seedling length and biomass of six varieties of green gram seedling were recorded. The dye industry effluent did not show any inhibitory effect on seed germination at lower concentration (10%). But , the higher concentrations beyond 25% suppressed the germination. On the basis of seed germination and growth performance, the green gram varieties have been arranged in the following order, ADT-5<ADT-3<T-9<MI-121<K-11< TMV-4 according to their tolerence to dye industry effluent. From this study it has been reported that the untreated dye industry effluent is toxic even at germination stgae. So, it should be treated properly before they are discharged into nearby water bodies. The treated and diluted effluent can be utilized for agricultural irrigation.

Abstract: The sewage irrigated soils of peri urban area nearby Vadodara city was surveyed to know the heavy metals contamination and nutrient status of sewage irrigated fields. The soils were found alkaline in reaction with build up of soil salinity besides increase in organic carbon, available P and K as well as micronutrients (Fe, Zn) over tube well irrigated soils of adjoining area. The contents of P, K, S, micronutrients as well as heavy metals were more concentrated in upper 30 cm depth in both the soils. Among the metals, DTPA-Fe(r=0.657**), Cu (r=0.637***) and Pb(r= 0.739*) showed positive correlation with organic carbon in sewage irrigated soil. The average avilable and total contents of heavy metals viz., Pb, Co and Ni were also higher in sewage irrigated soils than adjacent tube well irrigated soils. The findings of the present investigation emphasize the contamination of soils in peri urban areas especially with heavy metals viz., Pb, Ni and Co which are irrigated with sewage water over theb years.

Abstract: An assessment of land quality was carried out for coffee-growing areas of Karnataka using satellite image, toposheets and soil studies. The investigation focussed on monitoring soil processes that control the land quality using satellite data in order to identify the land qualities that are ideal for coffee-growing; to identify the status of land qualities of coffee-growing areas using satellite imageries, toposheets and soil resources maps and to characterise qaulity using soil studies inselected areas. The quality was characterised using climatic data, terrain analysis and soil attributes. From the study it was observed that coffee growing lands of Gabbugal and Kelagur have best land qualities and coffee-growing areas of Balur and Nellikkad have moderate land qualities. Satellite image and aerial photographs were successfully used for monitoring the land quality and its changes in these areas. For optimum utilization of available natural resources on a sustainable on a sustainable basis, timely and reliable information on soils regarding their nature, extent and spatial distribution along with their potential and limitations is very important. The efficiency and accuracy of data are improved when remote sensing data products such as aerial photographs and satellite image are used.

Abstract: Rapid urbanization causes disorganized and unplanned growth of towns and cities. The pressure of an ever growing population becomes a burden on the limited civic amenities which are virtually collapsing. Asymmetrical growth of urban centres consumes agricultural land adjuscent to these, resulting in lower agricultural productivity. Besides taxing the groundwater resources available for an urban centre, an increase in the paved area severely reduces the groundwater recharge potential, leading to situations which may be potential catastrophes. An understanding of the growth dynamics of urban agglomerations is essential for ecologically feasible developmental planning. With almost third of India ' s population already having become urban, it is necessary to acquire information on growth patterns of cities and how they impact the living environment. The current trend of spatial urban growth in almost all Indian cities has a haphazard pattern, particularly along the urban-rural fringe. There is an obvious need for continuously monitoring the phenomena of growth, and mapping and analyzing its patterns, since this is of great concern to urban administrators and planners whose concern it is to provide basic amenities and infrastructure for the complex urban environment. Mapping urban growth by conventional methods is too tedious and a slow process, and by the time information becomes available to planners, it is already outdated and redundant since the damage has already been done. Satellite remote sensing data and application of GIS technologies provide an alternative means of rapidly assessing the dynamics and development of sprawl so that timely action may be taken. Besides being flexible and extensible, the datasets are rectified, updated and may be used for other applications. the present study carried out using landsat, IRS and QuickBird data to delineate the extent, pace and pattern of growth of the city area of Aligarh. The study reveals that the urban area has increased almost three times since 1971. The rate of land consumption for urban purpose was substantially moderate till 1980s, but in the 1990s witnessed a sharp increased in land consumption as compared to population growth. The city still does not have a sewage treatment plant, and of the estimated 40 mld (million litres per day) of sewage produced by a population of 7,89,529, only 27 mld is pumped out or diverted for irrigation purposes, while the rest pollutes the urban environment or contaminates the ground water resources. Land consumption for urban purposes in the last fifteen years is estimated to be 1.428km2 per year. besides, substantial land acquired by city dwellers for intended urban purposes along the urban-rural fringe has been rendered saline.

Keywords: High-resolution images, Hydrological mapping, Ground water prospects
Abstract: Water is the most important natural resource which forms the core of the ecological system. The advent of remote sensing has opened up new vistas in groundwater prospect evaluation, exploration and management. The groundwater resources of the study area, Rishikesh region of Garhwal Himalaya, are under threat due to population pressure caused by expanding tourism in this region. This entails sustainable and judicious use of this precious resource. The groundwater prospect evaluation in Rishikesh region has been attempted based on hydrogeomorphological mapping of the area consisting of thematic maps of hydrogeomorphology, geology, drainage, lineament, slope and and relief using high resolution IRS-1C LISS III and PAN merged satellite images. The Rishikesh region exhibits diverse hydrogeomorphological conditions where the groundwater regime is controlled mainly by topography and geology. A probability-weighted approach has been applied during overlay analysis in Arc Map GIS environment. The overlay analysis allows a linear combination of weights of each thematic map with respect to ground water potential. Good groundwater prospects dominate in the area with more than 50% of the study area showing moderate to excellent potential. The study shows that the remote sensing and geoinformatics techniques can be applied effectively for groundwater prospect evaluation.

Abstract: This article reports a preliminary work in which two site seasonal algorithms have been proposed for estimating the suspended sediments concentration (SSC) from the digital numbers recorded on Indian Remote Sensing Satellite, IRS-P4 Ocean Colour Monitor ( OCM) sensor. For estimation of SSC, the proposed algorithms utilize dark pixel deduction atmospheric correction technique. The computations are performed with respect to north east monsoon phase situations of Palk Strait coastal stretch. The algorithms performance was satisfactory during the north east monsoon period. Although the results obtained cannot be generalized, we suggest that the authority of proposed algorithms can be extended to other seasons with the addition of more temporal experimental validation data sets and with numeric constants adjusted to present existing conditions(As this area was severely affected by Tsunami, it may have dissimilar conditions at present).

Abstract: Synthetic Aperture Radar (SAR) images are corrupted by speckle noise due to random interference of electromagnetic waves. The speckle degrades the quality of the images and makes it difficult to interpret, analyse and classify. this paper proposes a method that reduces the speckle and preserves the features by using scale-space correlation between the scales. The results show that the proposed method is better than the widely used filters based on the spatial domain, such as Lee, Kuan , Frost, Ehfrost,Median, Gamma filters in terms of feature preservation. Moreover the proposed method achieves a wide range of balances between speckle reduction and feature preservation, and thus is application in different applications such as road detection, detection/ identification of bridge, and ribbon like structures. Furthermore, the proposed method does not require prior modeling of either the image or noise statistics. It uses the variance of the detail wavelets coefficients to estimate noise variance.
