DOWNLOAD EBOOKEutrophication 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.

DOWNLOAD EBOOKEutrophication is the increase of plant nutrients--particularly nitrogen and phosphorus--into water beyond the natural concentration, thus encouraging plant growth that can clog waterways, make treating the water for drinking more difficult, and inhibit fish life by depleting oxygen. Harper (zoology and education, U. of Leicester, England) explains the causes and effects, and management options. Addressed to freshwater scientists and engineers, and advanced students. Acidic paper. Annotation copyrighted by Book News, Inc., Portland, OR

DOWNLOAD EBOOKShallow lakes are important for their amenity value and the ecosystem services that they support. However, many are located in areas of high population density and intensive farming activity. As such, they are subject to many stressors, including eutrophication and climate change. This book examines 40 years of data from Loch Leven, a shallow lake in the lowlands of Scotland, UK, to gain a better understanding of the links between pollution, climate change and ecological response at the landscape scale. A wide range of topics is presented, including long term changes in nutrient inputs, internal phosphorus loading, water quality, algal concentrations, and the biodiversity of macrophytes, zooplankton, benthic invertebrates, fish and waterfowl. The book provides evidence that attempts to improve ecosystem services at this site in the past have often resulted in unintended consequences for the lake and the local community. It concludes that successful management actions in the future are likely to be those that incorporate lessons learned from previous decisions. This book will be of great interest to freshwater ecologists working in the field and managers responsible for the protection and monitoring of natural areas. It is also suitable as a supplementary text for courses in freshwater science and environmental management

DOWNLOAD EBOOKScotland is fortunate in being very richly endowed with natural fresh waters in the form of numerous lochs and rivers. These constitute on the one hand an attractive feature of the landscape and on the other a major resource for industry and recreation. Thus there are about 3800 lochs over4 ha in area and these form approximately 1.0% of the total surface area of Scotland. Com parable figures for England and Wales are 1700 lakes and 0.05% of the land surface, and in terms of volume. Loch Ness contains more water than all the lakes and reservoirs in England and Wales put together (Smith & Lyle 1979). Many of the Scottish lochs are large and clean and consequently are particularly valuable in resource terms. The decision as to which are actually the largest lochs is debatable, particularly when the main criteria of greatest surface area, length, volume and depth each gives a different water (Lochs Lomond. Awe, Ness and Morar respectively). These four then are certainly among the largest lochs in the country, but close to them in size come several other large waters, among which is Loch Shiel- which is exceeded in length only by Lochs Awe, Ness and Lomond. These five very large lochs (Frontis piece) form the group of waters selected for the comparative studies described in this volume.
