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.

Groundwaters of New Zealand is the definitive new source for information on the groundwater resources of New Zealand. Written by many of New Zealand's leading experts, the book covers varied aspects of groundwater research, assessment, use, and management in New Zealand.

Chapters document the history of groundwater development in New Zealand, and current research on interactions between groundwater systems and other components of the hydrological cycle. Groundwater quality is explored in chapters on groundwater chemistry and microbiology, and on the health aspects of groundwater. The book also contains detailed regional summaries, covering the location, use, quality, and management of groundwater resources, for the entire country.

This book will be the essential reference text for all environmental, engineering, and resource management professionals working with groundwater, and students of the many scientific and engineering disciplines that contribute to groundwater investigations. Senior secondary school, undergraduate university students, and the many groundwater users will find this book a valuable reference that adds significantly to their understanding of groundwater resources.

Groundwaters of New Zealand
Michael R. Rosen and Paul A. White, editors
New Zealand Hydrological Society Inc; Wellington North, New Zealand; ISBN0-473-07816-3; 498 pp; 2001; $89.00
Groundwaters of New Zealand attempts to bring together in one volume a complete reference guide to groundwater research and resources in New Zealand. It was written to provide a "state of the art" snapshot of groundwater research, ideas and developments, and current and historical references that encompass the entire country. To this end, this well written, illustrated, and documented book is a grand achievement. However, as an island nation the approximate size and population of the state of Colorado, the book could do a better service by providing a perspective of New Zealand groundwater research and management in relation to practices outside of its borders. With that said, the book is admittedly written with updates in mind, meaning future additions can address areas of advancement and concern as needed.
The book consists of two main sections; the first section summarizes New Zealand's historical and current groundwater resources, its quality, management practices, important physical processes, and common research and evaluative techniques. Each subject is addressed in a separate chapter and is presented as the current status within New Zealand. The second section provides a regional look at groundwater resources, with a separate chapter devoted to each of the 15 regions within New Zealand.
The first two chapters address the history of groundwater development and the current known state of groundwater resources in the country. This historical context provides a foundation for understanding the problems that New Zealand, and the rest of the world, face today regarding water resources. The value of these chapters is extended by the inclusion of the history of New Zealand groundwater laws, regulations, agencies, and management bodies, which again provides context for understanding the current state of groundwater management.
The balance of the first section address separate groundwater topics that are specific concerns within New Zealand. Each topic is a separate chapter with subjects ranging from hydrochemistry of New Zealand aquifers to groundwater-surface water interaction to microbial contamination. Each individually referenced chapter starts with an introduction that frames the importance of the subject to New Zealand, followed by discussions of relevant past studies, current research and status, and future considerations. In most cases, the author(s) of each chapter is(are) directly involved in the topic and are considered the local expert on the subject. Employing an expert author for each chapter has the advantage of a higher level of knowledge being passed to the reader, but the disadvantage of disparate writing styles and chapter formats. However, given the disadvantages, an interested reader should have no problem in finding the information they seek.
The second section of the book addresses the groundwater resources within each of the 15 regions of New Zealand. The Regional Councils, which are the governing bodies at the regional level, are responsible for groundwater resource evaluation and management as it pertains to local quantity and quality issues. Thus each regional summary is authored by the resident groundwater manager(s) within each Regional Council. Each chapter addresses the relative importance of groundwater in the region, the location and description of the primary aquifers, pressures on the groundwater resources, management objectives and approaches, and unique regional features (e.g., hydrothermal resources). What is most evident about these chapters is the variability of groundwater investigations and active management across the regions, with those regions that have a high reliance on groundwater resources, such as Canterbury and Auckland, being further ahead in understanding and managing their groundwater resources, than regions with low reliance (or pressure), such as the West Coast region.
By providing a snapshot of current groundwater usage, management, and science, Groundwaters of New Zealand provides a basis for future studies, coordination, and collaboration, for scientists within and outside New Zealand. For those inside New Zealand, the book provides an excellent resource for referencing past studies and current work to avoid redundancy and misappropriation of funding resources. For those outside New Zealand, the book provides a source of possible collaborative relationships as well as an example of how a single nation approaches the subject. While New Zealand's size lends itself well to documenting the current national status of groundwater science and management, Groundwaters of New Zealand should serve as a template for other nations, states, and/or regions to document their own efforts. To this end, Groundwaters of New Zealand is a valuable read to anyone interested in groundwater science and groundwater resource management.

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.

Floods and Droughts

The standard image of New Zealand is one of peaceful green pastures and sunny country towns. However, the New Zealand experience can be very different. Floods and droughts can affect virtually all parts of the country, from Northland down to Invercargill, in any year. 

"Floods and Droughts: the New Zealand experience" aims to summarize the wealth of observation and analysis of floods and droughts in New Zealand. Chapters are contributed by 20 hydrological scientists and water resource professionals, who have worked on many different aspects of floods and droughts. Some chapters present observations of historically significant floods and droughts, and review different approaches to their analysis. Others consider the cause-and-effect relationships between fllods and droughts, land use changes, instream uses such as ecosystem maintenance, erosion and sedimentation processes, and the behaviour of groundwater resources. A final pair of chapters focuses on approaches to management of floods and droughts that are being developed in this country., and discuss four specific case studies. The book aims to be a reference text for water scientists, engineers and resource managers whose work requires them to better understand and to manage floods and droughts. It is intended, too, as a source for senior undergraduate and postgraduate university students in engineering, resource management, geography, and related disciplines. While presenting the experiences of practitioners in New Zealand, the book is intended to have value to water professionals in many other countries.


What others think

The book deals with multiple facets of extreme hydrological events. It covers a whole spectrum of problems related to floods and droughts, including lesser known aspects that seldom find their way into similar monographs. There is ample discussion of the climatic and meteorological conditions responsible for extreme events. An anatomy of case-studies of floods and droughts is presented and a sound statistical approach to drought- and flood frequency analysis is offered. The issues of managing extreme events, sustainable management of natural and physical resources, risk management and legislation are also dealt with. Environmental effects of extreme high/low flows, their impacts on flora and fauna, including recolonisation and ecosystem recovery after an extreme hydrological event, are included. Furthermore there is a discussion of the influence of extreme hydrological events on erosion and sedimentation. Climate-change impacts are also discussed. So are ground-/surface water interactions in the context of extreme hydrological events. Among other topics tackled are problems of data and observation networks, experimental catchments studies and regionalisation.

This book is a fine example of a monograph on floods and droughts, which continue to afflict many countries of the world. It gives factual information about the region and can be seen as a welcome contribution to the International Decade for Natural Disaster Reduction, encouraging countries to increase their awareness of natural disasters, assess risk, and improve preparedness. The editors and all contributors to individual chapters are to be commended for their product. The book will surely attract the interest of a broad international readership.
