Selected Proceedings of the 1st International Specialised Conference on Water Quality and its Management, held in New Dehli, India, 2-6 March 1998. Water resources development should not only ensure water supply in the right quantity at the right time but also ensure that the water is of the right quality. While drinking water must meet stringent quality standards, water quality is also important for agricultural, industrial and other uses. Increasing pollution, urbanisation and industrialisation has lead to a growing threat to water quality in rivers and lakes. Groundwater quality can also be affected as a result of the use of agrochemicals, wastewater irrigation, and salinity and landfill leachate intrusion. Such problems are often most acute in developing countries where water is short to begin with. This was the subject matter of Water Quality and its Management. From over 200 original submissions, 67 were orally presented, many of direct and practical regional relevance. After peer review, a further selection was made, of high-quality papers of significant interest to the worldwide readership of Water Science & Technology. Twenty-four of these papers are included here, categorized into the six major sub-themes of the conference: Impact of Industry and Agriculture on Water Quality Surface Water Quality Management Groundwater Contamination Issues Drinking Water Quality Management Use of Low-quality Waters and Wastewaters Water Quality Improvement Methods, Techniques and Technologies

Water Quality Management covers the fundamentals of water quality; water quality modeling and systems analysis of streams, reservoirs, and estuaries; and practical water quality topics and problems. The book presents topics on the legal aspects; the physical, chemical, and biological dimensions of water quality; and water quality requirements. The text also describes the pollution inputs from both point and nonpoint sources; eutrophication; thermal pollution; and groundwater quality. Detailed discussions on water quality parameters and characteristics; hydrologic and hydraulic aspects of water quality; mixing; and simple and complex water quality models are also included. The book further tackles topics on waste assimilative capacity determination, as well as effluent outfall design. Practicing environmental engineers and professionals involved in pollution abatement programs, environmental students undertaking studies in water quality management, and professionals involved in water quality management or water resources problems will find the text quite.

The global attention in recent years has focused primarily on water quantity and allocation issues. Water quality has received significantly less attention than water quantity. Commendable progress has been made by the developed world to control point sources of pollution, but commensurate progress in reducing non-point sources has not been made. In the third world countries both point and non-point sources of pollution are becoming increasingly a serious concern. Already, nearly all water bodies in such countries near and around urban centres have been severely polluted, with very high health and environmental costs. The book assesses the current status of water quality management in both developed and developing worlds, as well as analysing the effectiveness of economic instruments and legal and institutional frameworks to control water contamination. It outlines the importance of building up social and political awareness to reverse the trend of continuing water quality deterioration, which is likely to be a most challenging task in the coming years. This book was published as a special issue of International Journal of Water Resources Development.

The book describe the fundamental aspects water resources and water quality management, and environmental problems related to acquaculture in the Coastal related to aquaculture in the coastal areas. It addresses to the surface and ground water resources and their characteristics, in general and inherent in the coastal water environment, and describes the coastal environment with ecological divisions and coastal regulation Zones. Water resource use is highlighted mainly in coastal fisheries and aquaculture, and also in multiple uses for agriculture, forestry and waste disposal. Impacts of resource use on the coastal environment with potential and specific cases have been discussed. The book focuses on water quality aspects with the basic management issues such as physico-chemical, biophysical and biological parmeters and their interactions on the dynamics of the systems in a water body. On water quality management included are the topics under pond water treatment for control and management of aquatic environment for culture practices, and on farm effluent treatment for reduction of environmental impact in the surrounding water bodies. Related numerical problems have been given as examples in most of the chapters, as well as few sample questions for students work. The content of the book extends our theoretical understanding of water resource and water quality management, and also provides how-to or practical advice for professionals in the aquaculture industry.

Considerable attention has been given during the past few years to the water crisis that many regions of the world may face in the coming decades. While the mag- tude and the extent of the global water scarcity problems of the future should not be underestimated, a serious analysis of the current trends indicate that the main water crisis in the coming years is most likely to stem primarily from water quality deterioration and lack of investment funds, rather than from physical water scar- ties per se, as is widely expected at present. In spite of the seriousness of continuing water quality deterioration in most countries of the world, water quality management continues to be a somewhat - glected issue in the international water community. Even the magnitudes and - tents of the water quality problems are not reliably known in many developed countries and in nearly all developing ones. Accordingly, in order to assess the current situation in water quality management in the Americas, and to discuss the alternatives available to improve the existing and future water quality conditions in a cost-effective and timely manner, the Third World Centre for Water M- agement in Mexico, the National Water Agency in Brazil (Agência Nacional de Águas), and the Inter-American Development Bank organised a workshop on “Water Quality Management for the Americas,” in Fortaleza, Brazil, 12-13 April 2004.
