Assessment of water quality of a river-dominated estuary with hydrochemical parameters: A statistical approach.
(Springer, 2014)This study was aimed (1) to evaluate the water quality of Chalakudy river, the fifth longest (145.5 km) river of Kerala (South India), by assessing the general hydrochemical parameters like temperature, dissolved oxygen ... -
Assessment on seasonal variation of groundwater quality of phreatic aquifers - A river basin system
(Springer, 2006)Spatial distribution of pH, electrical conductivity (EC), total dissolved solids (TDS), fluoride and total iron content of ground water samples collected from the muvattupuzha river basin, Kerala, India, has been studied ... -
Assimilation potential of water column biota: Mesocosm-based evaluations
(Tata Energy Research Institute, India, 2003)This chapter presents a generalized picture of various aspects of assimilation by native biota and underscores the importance of safeguarding the environment from excessive discharge of nutrient-rich effluents, even though ... -
Bacteriological quality of creeks and marine water bodies in North Goa: Ecosystem upkeep perspectives for tourism-related activities
(Tata Energy Research Institute, India, 2003)Keeping tourism-related activities in the fore, several relevant bacteriological parameters were studied in depth in North Goa's aquatic ecosystems. Total bacterial abundance and activity for sewage-indicator bacteria and ... -
BOD-DO modeling and water quality analysis of a waste water outfall off Kochi, west coast of India
(Elsevier, 2006)Water quality scenarios around an offshore outfall off Kochi were simulated using MIKE21 water quality model, assuming a high Biochemical Oxygen Demand (BOD=50 mgl sup(-1)) effluent discharge. The discharge is introduced ... -
Changes in water quality at Cochin harbour dredging site, south west coast of India
(NISCAIR, CSIR, 1998)The water quality in the vicinity of the dredging did not show any appreciable change. All dissolved nutrients recorded sharp changes in the water column. After 20 minutes and 2 hours, the conditions at the dredging were ... -
Dispersion and retrievability of water quality indicators during tidal cycles in coastal Salaya, Gulf of Kachchh (West coast of India)
(Springer, 2010)Bacterial indicators in relation to tidal variations were studied at five locations for over 2 days covering three tidal cycles in the southwestern region of Gulf of Kachchh, India. Tidal flow here is predominantly in the ... -
Dissolved oxygen - A target indicator in determining use of the Gulf of Kachchh waters
(Elsevier, 2005)Spatial and temporal variations of Dissolved Oxygen (DO) and Biochemical Oxygen Demand (BOD) in the Gulf of Kachchh (GoK), India are assessed based on data collected since 1976.DO concentrations in the interior GoK vary ... -
Distribution and abundance of copepods in the pollution gradient zones of Bombay Harbour-Thana Creek-Bassein Creek, west coast of India
(NISCAIR, CSIR, 1997)Forty six species of copepods were identified, of which, 40 belonged to Calanoida with an overall dominance of Acartiidae. Acartia spinicauda, A. centrura and Centropages dorsispinatus were the common species throughout ... -
Evaluation of significant sources influencing the variation of water quality of Kandla creek, Gulf of Katchchh, using PCA
(Springer, 2010)To evaluate the significant sources contributing to water quality parameters, we used principal component analysis (PCA) for the interpretation of a large complex data matrix obtained from the Kandla creek environmental ... -
Factors controlling physico-chemical characteristics in the coastal waters off Mangalore - A multivariate approach
(Elsevier, 2009)Water quality parameters (temperature, pH, salinity, DO, BOD, suspended solids, nutrients, PHc, phenols, trace metals-Pb, Cd and Hg, chlorophyll-a (chl-a) and phaeopigments) and the sediment quality parameters (total ... -
Groundwater chemistry of shallow aquifers in the coastal zones of Cochin, India
(Penkala Bt., 2005)The coastal aquifers of Kerala, India experience severe degradation of water quality due to various anthropogenic activities. An attempt is made here to study the groundwater chemistry of aquifers, which lie along the ... -
Health status of the coastal waters of Mumbai and regions around
(Bookwell, New Delhi, India, 2000)The coastal marine environment of Mumbai, Maharashtra, India and regions around receives the domestic wastewater generated of around 1800 million litres per day (mld), mostly untreated. In addition, a large number of ... -
