Water has become one of the most important issues of our time intertwined with global warming and population expansion. The management of water supplies and the conservation of water resources remains one of the most challenging yet exciting issues of our time. Water and wastewater treatment technologies are constantly evolving creating an increasingly sustainable industry that is one of the world's largest and most interdisciplinary sectors, employing chemists, microbiologists, botanists, zoologists as well as engineers, computer specialists and a range of different management professionals. This accessible student textbook introduces the reader to the key concepts of water science and technology by explaining the fundamentals of hydrobiology, aquatic ecosystems, water treatment and supply, wastewater treatment and integrated catchment management. This fourth edition is extensively changed throughout, with new coverage of the effects of climate change, environmental assessment, sustainability and the threat to biodiversity. The text serves as a primer for both undergraduate and graduate students in either science or engineering who have an interested in freshwater biology/hydrobiology or environmental engineering. It is also useful as a unified transitional course for those who want to span the traditional areas of engineering, biology, chemistry, microbiology or business. Professionals and consultants will also find the book a useful reference.

Looking back at the lives and sailing careers of some of our lifetime's finest yachtsmen, this collection of eleven original, moving accounts is just as much a celebration of the good - tales of hope, achievement and courageous spirit - as it is an account of their tragic final voyages. Included are world-renowned racers, like Eric Tabarly and Rob James, highly experienced cruisers and adventurers, like Peter Tangvald and Bill Tilman, and the notoriously ill-prepared Donald Crowhurst, as well as other famous and some less well-known sailors. Starting with the sad loss of Frank Davison and Reliance in 1949, the book concludes with the amazing last voyage of Philip Walwyn in 2015 - crossing the Atlantic single-handed in his 12 Metre yacht Kate. All of the men and women described were friends with or known to the author, Nicholas Gray, who himself competed in several short-handed long distance races, where he met and raced against many of these fascinating characters. Peppered with photographs showcasing the sailors and their yachts, this is a refreshing look at those who have helped to shape this sport's history, honouring their lives and accomplishments before detailing their tragic last voyages.
