Book Description
The first symposium on sediment/freshwater interactions was held in Amsterdam, in 1976, and the second was held at Kingston, Ontario, Canada, in 1981. The third symposium was held at the University of Geneva, in 1984, and also included a num ber of contributions dealing with sediment/saltwater interactions. It is expected that future symposia of this series will retain this approach, and that the revised sympo sium title will remain the same for later proceedings of these meetings. Because of the large number of submissions in 1984, many were given as poster presentations. Extended abstracts of all contributions to the Geneva symposium appear in Interactions Between Sediments and Ubter (C. E. P. Consultants Ltd. , 26 Albany St. , Edinburgh, EHI 3QH, U. K. , 1984). Full-length papers appear only in the proceedings. The format of the third symposium was similar to its predecessors. The location provided a particularly good opportunity for attendance by European scientists, who represented about 81% of the participants. About 16% came from North America and 3% were from Southeast Asia and Australia. It is unfortunate that there were no contributors from either Africa or South America, or other parts of Asia. In all, 16 countries were represented at this symposium. In a continuing attempt to provide equal opportunities for attendance by scientists from other parts of the world, it is planned to hold the next symposium in Australia in 1987. Further information about the symposia series can be obtained from Dr. E. D.

Book Description
The vast majority of the world's lakes are small in size and short lived in geological terms. Only 253 of the thousands of lakes on this planet have surface areas larger than 500 square kilometers. At first sight, this statistic would seem to indicate that large lakes are relatively unimportant on a global scale; in fact, however, large lakes contain the bulk of the liquid surface freshwater of the earth. Just Lake Baikal and the Laurentian Great Lakes alone contain more than 38% of the world's total liquid freshwater. Thus, the large lakes of the world accentuate an important feature of the earth's freshwater reserves-its extremely irregular distribution. The energy crisis of the 1970s and 1980s made us aware of the fact that we live on a spaceship with finite, that is, exhaustible resources. On the other hand, the energy crisis led to an overemphasis on all the issues concerning energy supply and all the problems connected with producing new energy. The energy crisis also led us to ignore strong evidence suggesting that water of appropriate quality to be used as a resouce will be used up more quickly than energy will. Although in principle water is a "renewable resource," the world's water reserves are diminishing in two fashions, the effects of which are multiplicative: enhanced consumption and accelerated degradation of quality.
