Use of coastal, estuarine and freshwater recreational environments has significant benefits for health and well-being, including rest, relaxation, exercise, cultural and religious practices, and aesthetic pleasure, while also providing substantial local, regional and national economic benefits. These guidelines focus on water quality management for coastal and freshwater environments to protect public health. The guidelines: 1. describe the current state of knowledge about the possible adverse health impacts of various forms of water pollution; and2. set out recommendations for setting national health-based targets, conducting surveillance and risk assessments, putting in place systems to monitor and control risks, and providing timely advice to users on water safety.These guidelines are aimed at national and local authorities, and other entities with an obligation to exercise due diligence relating to the safety of recreational water sites. They may be implemented in conjunction with other measures for water safety (such as drowning prevention and sun exposure) and measures for environmental protection of recreational water use sites.

This established textbook continues to provide a comprehensive andstimulating introduction to rivers, lakes and wetlands, and waswritten as the basis for a complete course on freshwater ecology.Designed for undergraduate and early postgraduate students who wishto gain an overall view of this vast subject area, this accessibleguide to freshwater ecosystems and man's activities will also beinvaluable to anyone interested in the integrated management offreshwaters. The author maintains the tradition of clarity andconciseness set by previous editions, and the text is extensivelyillustrated with photographs and diagrams. Examples are drawn fromthe author's experience in many parts of the world. In this edition, the scientific content of the text has beenfully revised and updated. Emphasis has been placed on humanimpacts, and a completely new chapter has been added on the futureof freshwaters. Balanced and stimulating introduction to limnology. Successfully combines fundamental and applied aspects ofintegrated management of freshwaters, with strong emphasis on humanlinks. Completely revised and rewritten with a threefold increase inthe number of illustrations. New chapter on the future of freshwaters. Of interest to undergraduates, beginning postgraduates and anylimnologically interested reader.

Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

These new Guidelines for Safe Recreational Water Environments describe the present state of knowledge regarding the impact of recreational use of coastal and freshwater environments upon the health of users - specifically drowning and injury, exposure to cold, heat and sunlight, water quality (especially exposure to water contaminated by sewage, but also exposure to free-living pathogenic microorganisms in recreational water), contamination of beach sand, exposure to algae and their products, exposure to chemical and physical agents, and dangerous aquatic organisms. In addition, control and mo.

Coastal reservoirs are viewed in many regions of the world as an emerging concept of storing fresh water when the river basin is in flood. Similar reservoirs (or impoundments) can be used to generate tidal renewable energy and/or provide the catalysis for urban regeneration. Constructed near the coast in natural river basins, these reservoirs have a smaller environmental footprint and are less obstructive than inland dams. Written by an international group of Civil, Environmental, and Geotechnical Engineers, Sustainable Water Resource Development using Coastal Reservoirs discusses the latest research and breakthroughs in their use, while offering expert advice into their sustainable design and construction. The perfect reference for researchers exploring the feasibility of this emerging technology or experienced professionals who wish to implement this technology as a water scarcity solution or a tidal renewable energy source or for urban regeneration, Sustainable Water Resource Development using Coastal Reservoirs provides an expert resource to the design, construction and use of coastal reservoirs. The reference begins with a brief but readable examination of water quantity, quality design and geotechnical considerations. The book includes international case studies to clearly illustrate the various uses, design, planning, construction, and operation methods. These case studies include projects such as: Afsluitdijk in the IJsselmeer, (Netherlands), Zuiderzee (Netherlands), Thanneermukkom Bund (India), Sihwa (South Korea), Saemangeum, (South Korea), Chenhang (China), Plover Cove (China), and Marina Barrage (Singapore).

Eutrophication is a problem which became widely recognised by the scientific community in the 1940s and 1950s. It raised public concern, resulting in increased research effort and expenditure on management techniques through the 1960s and 1970s, recognised as a distinct problem of water pollution, though linked with the more gross effects of organic pollution. In the 1980s it became less fashionable - replaced in the public's eye and the politician's purse by newer problems such as acid rain. It remains however, one of the biggest and most widespread problems of fresh waters, particularly of lakes and an increasing problem for estuaries and coastal waters. It is one with which almost all water scientists and engineers in urbanised areas of the world have to cope. Technical methods for the reversal of eutrophication, such as nutrient removal, have been developed and applied successfully in some instances. They are not widespread however, and where they are feasible, they are often expensive and may be politically difficult to implement. In the last decade, attention has focussed upon less expensive lake manipula tion techniques, such as destratification and biomanipulation, which aim to minimise rather than elimininate the detrimental effects of eutrophication. These are becoming more widely applied. Prediction of the potential problems in lakes and catchments which have not yet suffered the full effects of eutrophication is now accurate enough to be of direct benefit to river basin management.
