The research presents water quality analysis of Bhadravathi in Karnataka State, India. Fourteen physico-chemical and biological parameters were considered for the analysis. The raster maps created using GIS are used to represent the spatial distribution of the parameters for both pre and post-monsoon seasons. Using physico-chemical parameters, Water Quality Index (WQI) was determined. The WQI shows 11% of the surface water samples fall under very good category during pre-monsoon and 78% in post-monsoon. The water sample at New Bridge site shows sign of pollution throughout year with WQI in the range 50-100 and hence unfit for use. In groundwater samples, 20% of samples in the pre-monsoon and 50% samples during post-monsoon fall under good quality. 50% of water samples during pre-monsoon and 60% of samples during post-monsoon fall under good category and water sample at Haladamma temple are found unfit. Further, QUAL2K model predicted the DO and BOD values considerably well along the Bhadra River from Lakkavalli to Bhadravathi Town. However, the Streeter Phelp s model estimated higher DO as compared to QUAL2K model. This is due to provision of outfall effect in Streeter Phelp s model.

The approach of this book is to promote an understanding of surface water quality, including the hazards that can compromise water quality and develops effective measures to assess and manage risks arising from those hazards using spatial and statistical models. Evaluation of 42 drinking water quality parameters has been done on a monthly basis during 6 years. Applying a GIS tool will provide visual impacts for various hazards using WQI, which has formed a series of prediction maps for risk assessment. The results showed that surface water is remarkably influenced by wastewater discharge, especially at drought period. Prediction model proved a practical and economical value that gives an easier and effective solution through selecting the best decisions to enhance water quality, assurance of public health protection can be gained and be providing a comprehensive preventive strategy for drinking water system management can be achieved. The book is written for post-graduates, researchers and professionals involved in water quality monitoring and assessment of surface waters and want to improve the scope and reliability of their systems with using water dynamic prediction models.

An integrated survey based on satellite image interpretation corroborated with limited field checks were carried out with a view to delineate the ground water potential in parts of Y.S.R District district, Andhra Pradesh, South India. The interpretation of Remote Sensing data & GIS in conjunction with conventional data and sufficient ground truth information makes it possible to identify and outline various ground features such as geological structures, geomorphic features and their hydrologic characters that may serve as direct or indirect indicators of the presence of ground and surface water. In the present study, a detailed investigation was carried out with an objective of identifying the index of groundwater by using Water Quality Index (WQI) method. Prominent water quality parameters controlling the hydrochemical evolution of aquifer system was studied.

Surface water ecosystems are complex with interlinked physical, chemical and biological systems. Day to day activities of Human causes changes in these attributes thus affecting the aquatic living resources over time. In the case of fresh water resources, municipal sewage, agricultural run-off and industrial effluents gets discharged into streams, lakes and rivers thereby making these water resources unsuitable for drinking purpose. Since water is a universal solvent, most of the pollutants get dissolved easily which degrades the overall surface water quality. Therefore, it is necessary to conduct periodic monitoring of water resource. It not only helps in recording the levels of various pollutants in water bodies but also help policymakers, government bodies to formulate policies that can help protect the human health and the environment.
