Freshwaters of New Zealand has been written by a team of eighty scientists and managers. It provides an up-to-date survey and synthesis of our knowledge of the streams, rivers, wetlands and lakes of New Zealand. There is a strong emphasis on our distinctive environment, science and management, but this is always underpinned by knowledge developed internationally. The 46 chapters cover a range of information, concepts and theories, arranged in five sections: the hydrological cycle, running water systems, lakes and wetlands, subsurface waters, and applications and issues in water management. The book is designed for students, managers, and scientists, working in a wide range of disciplines, who require an introduction to the field of freshwater science and management, and an entry point into the wider literature.

A long white cloud, snow and glaciers, tranquil lakes — part of the image that attracts thousands of tourists to New Zealand, and encourages many into careers as water managers and scientists. But there is far more to the freshwaters of New Zealand than these. Our knowledge of fresh water, aquatic biota and ecosystems has advanced rapidly in recent years. In addition to the "icons"— the salmon fisheries of the South Island, the blue duck of our mountain rivers — less well known life forms are receiving increasing attention, such as the animals that live in groundwater, often deep below the surface. To classic concepts such as the hydrological cycle and the river continuum, scientists are adding new hypotheses and theories, new management tools are being developed, and improved methods to facilitate community involvement are being applied.

FRESHWATERS OF NEW ZEALAND edited by Jon Harding, Paul Mosley, Charles Pearson, Brian Sorrell. Published by New Zealand Hydrological Society (PO Box 12-300, Wellington) and New Zealand Limnological Society, 700pp, $69.95 ($14 postage and packaging).
The hydrology and ecology of New Zealand rivers and lakes is presented in great detail in this book published by New Zealand hydrologists and limnologists. It is complementary to Groundwaters of New Zealand, published two years ago. The book will be a useful reference for scientists, students, resource managers and others whose interest is water and what goes on in it. Of particular significance are chapters dealing with currently newsworthy topics such as in-stream values, human health, wetlands, and the impacts of forestry, dams and pests. Many of the chapters deal with topics related to the negative impacts of our society on freshwater and how these may be avoided and remedied. An excellent resource to promote sustainable management of Canterbury's lifeblood - water.

Gravel-Bed Rivers V

Gravel-bed rivers are both fascinating and of great practical significance to water resources managers. This book reports the proceedings of the fifth Gravel-Bed Rivers Workshop, held in New Zealand in August-September 2000. The Workshop brought together over 100 international scientists and river managers, to present their current research and to debate many aspects of gravel-bed river behaviour and management. The 24 chapters are contributed by over forty specialists, with additional analysis provided by many more. Their topics covered almost every conceivable aspect of the science, ranging from the processes of sediment entrainment by turbulence through to the response of fish to variations in river flows.

Gravel-Bed Rivers V presents state-of-the-art technology and up-to-the-minute knowledge. The technological applications range from detailed measurements of eddy structures and turbulence at centimetre-scale, through to time-lapse video photography of the changing pattern of channels in a kilometre-wide braided river. Exciting developments in data capture, image analysis and computer modeling are enabling huge strides to be made in describing, understanding and predicting the form and behaviour of gravel-bed rivers. They have revealed, for example, the existence of dendritic networks of braid channels in large braided rivers, which places the processes of channel evolution in a quite different perspective.

The fifth Workshop made a particular effort to address management goals in gravel-bed rivers, such as maintaining healthy aquatic ecosystems or controlling aggradation. Ecological and fisheries scientists introduced recent research into the behaviour of aquatic ecosystems in gravel-bed rivers. They showed for example the crucial importance of disturbance by floods in determining the diversity and biomass of aquatic vegetation, invertebrates and fish, in association with entrainment and movement of bed material. A number of papers considered the philosophy and practice of river management in three continents. A field exercise in the Waiho River provided an opportunity for Workshop participants to consider how to manage channel instability and aggradation in one of New Zealand's major tourist venues.

The book provides an important source of information and ideas for scientists, engineers, and resource managers seeking to understand gravel-bed rivers better. It will be useful also for senior undergraduate and graduate students who are developing their own research directions, and seeking inspiration from the leaders in their field.


What others think

The content is a balance between new research findings and developments of already published work. There are several good overview chapters: for example, Paola on modelling stream braiding over a range of scales, Lane on measurements of gravel-bed river morpholopgy, and Willgoose on erosion processes, catchment elevations and landform evolution modelling. These are complemented by more specific studies such as those on discrete particle modelling and active tracers (McEwan et al.) and the consequences of unsteady sediment transport (Hoey et al.). There are several case studies including a strong New Zealand element. Probably the real strength of the book, as with previous GBR volumes, lies in the discussion and reply sections which follow the main papers. Virtually all the papers contain some element of discussion. These often contain very new research and ideas for further work. Much of the discussion tends to bring in examples of New Zealand rivers and thus makes good use of the conference location. The discussions also give a good feel for the vitality of the conference and the main issues discussed.

The editor is to be commended for ensuring that the volume emerged in the year following the conference. The previous volume (GBR IV) took four years to emerge. As research on gravel-bed rivers tends to advance rapidly, prompt communication of results is essential. Based on the evidence presented in the proceedings I would certainly like to have been at the conference, and I would have bought the book had I not received a review copy. Unlike earlier volumes in the series, it is reasonably priced.
