De fysische, geografische, chemische en biologische bestudering van het stilstaand zoete water

Continuing concern about water supply and quality, ecosystem sustainability and restoration demands that the modern approach to the management of lakes and reservoirs should be based on a sound understanding of the application of the scientific and ecological principles that underlie freshwater processes. The Lakes Handbook provides an up-to-date overview of the application of ecologically sound approaches, methods and tools using experience gained around the world for an understanding of lakes and their management. Volume one of the Handbook addresses the physical and biological aspects of lakes pertinent to lake management, emphasising those aspects particularly relevant to large, still bodies of water. Volume two then considers lake management, with particular emphasis on sustainability, restoration and rehabilitation. This handbook will be invaluable to ecologists, environmental scientists, physical geographers and hydrologists involved in limnological research, as well as advanced undergraduate and graduate students looking for authoritative reviews of the key areas of limnological study. Brings together basic science and management issues. International coverage and international authors. Reviews management issues at a level suitable for the non-expert.

Practical Guide to Managing Acidic Surface Waters and Their Fisheries explains how to manage acidic surface waters to preserve or restore fisheries. The work gives readers the basic tools to carry out a variety of surface water management activities. Topics include biological productivity and recovery, costs of liming, fish stocking, lake liming techniques, nutrients, regulations and permits, sampling, stream liming techniques, water quality analysis, and watershed liming techniques. The book will be a useful reference for fishing club managers, state and local government personnel, lake association managers, and others responsible for maintaining lakes and streams that may be affected by acidity from any source.
