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.

Concentrations in the Experimental Lakes Area (ELA) of northwestern Ontario declined by 15–25%. Decreased input of DOC is the primary reason for the 163 decline, although in-lake removal has accelerated slightly too. The experimental acidification of some of the ELA lakes was marked by accelerated DOC loss to internal removal. In one ELA lake, acidified to pH 4.5 during the 1980s, DOC fell to less than 10% of its pre-acidification level. 7.3.2 Responses to climatic change. Observations from.
Surface-water environments, apart from having metal-complexing properties similar to those of FAs, the carboxylic acids make highly available substrates for aerobic heterotrophs. Despite their bioavailability, transformation of organic matter into CO and CO2 metal chemistry is also rapid. Nevertheless, LMW organic compounds are important intermediates in the photodecomposition of HMW organic matter. Few studies have sought to calculate the significance of DHM photolysis at the ecosystem scale.
Reflection of current understanding about how lakes and lake ecosystems function. 1.2 THE LURE OF LIMNOLOGY We have also been keen to mirror two further modern perceptions underpinning current attitudes to limnology. One of these is the importance of the freshwater resource. Although over 70% of our ‘blue planet’ is covered by sea, lakes and rivers occupy only a tiny percentage of the (c.150 million km2) terrestrial surface. Nobody can say for certain just how many water bodies currently.
With the steep side facing windward if composed of clay, or the reverse if sandy. Finally, it should be stressed that during dry periods deflation tends to deepen and extend existing basins, and possibly also move them downwind. 2.5.9 Lakes formed by plant accumulation and by animals Lakes may also be formed by plant accumulation and by the activities of animals. Outbursts of raised peat bogs and dams of Sphagnum may be in- 33 Origin of Lake Basins volved in the formation of modest basins.
However, because ionexchange reactions can supply base cations to vegetation and runoff water for a period. Therefore, there may be a delayed response. Eventually, however, the exchange capacity of the soil will become depleted, and acidification will result. As an example, Fig. 4.7 gives the water composition of four lakes located at the top of the Maggia valley, Switzerland (Giovanoli et al. 1988), at an elevation of 2100–2500 m. Their small catchments are characterised by sparse vegetation (no.
