Glaciers and landscape: A geomorphological approach
198
symptomatic changes are found to be undesirable and interfere with water uses". In the Preface to the book, as in the 1970 report on Water Pollution in Australia, b y the Senate Select Committee, it is recorded that the rivers, streams, lakes, coastline and underground aquifers are being polluted in all States and Territories, and that some waterways can no longer be used except as sewers. It is evident that the quality of water as well as the quantity has n o w become important in Australia, that the quality is being endangered by pollution, due to the activities of man, and that the problems created b y increased eutrophication are causing special concern. The principal problems involved are discussed in this volume under the main headings of Recent Overseas Eutrophication Research, Basic Concepts of Trophic Status (and their applicability to Australian inland waters), The Effects and Problems Associated with the Eutrophication of Water, Eutrophication Problems in Australia, Indices and Measurement of Eutrophy (and their applicability to Australian waters), Management and Control of Eutrophication both Overseas and in Australia, and Eutrophication Research in Australia.

Glaciers and Landscape: A Geomorphological Approach. David. E. Sugden and Brian S. John. Arnold, London, 1976, 376 pp. UK £ 12.00 net (boards); UK £ 5.95 net (paper). The authors of this highly attractive glaciological work are members of the Geography staff of Durham University. In its preparation they have undertaken extensive fieldwork in many countries, including Iceland, Greenland and Antarctica. The b o o k is a study of glacial processes and forms. Not only is it a critical and creative synthesis of recent research, b u t it also provides significant modifications to accepted theory and approach. In each chapter, the authors have proposed models and hypotheses as an aid to understanding and a stimulus to inquiry. At the same time, they present fundamental data from a wide range of sources, with particular attention to current work in Greenland and Antarctica. Part I examines the properties of glacier ice, glacier systems and morphology. Part II is concerned with the distribution o f glaciers and includes a worldwide survey of short- and long-term glacier fluctuations. In Parts III and IV, the erosional and depositional effects o f glaciers are analysed. The basic processes are first identified, and their relationships with landforms and landscapes then described. Part V is devoted to meltwater as a glacial s u b s y s t e m and traces its influence on glaciers and on the processes of erosion and deposition. The b o o k is profusely illustrated with figures and photographs on almost
199
every page, specially prepared and closely integrated with the text. Lists for further reading are given at the end of each chapter. In addition there is a comprehensive bibliography of over 1,000 major references. The cover carries a false-colour ERTS image of the EjyafjSrdur region of North Iceland, showing a spectacular landscape of glacial erosion. The main chapter headings are Glaciers and glacial dynamics, Glacier distribution in space and time, Glacial erosion and its effects, Glacial deposition and its effects, and Meltwater: a glacial subsystem. The book should prove of special value to glaciology students, as well as the general scientific reader.
