River Mixing J. C. Rutherford NIWA Ecosystems, New Zealand Quantitative predictions of the rates of mixing of tracers (principally neutrally-buoyant tracers) in rivers are needed in a variety of situations including the preliminary design of outfalls, the impact assessment of discharges, water resource planning, and research on biological processes in rivers. River Mixing describes the theoretical basis for commonly-used mixing models, in order that the mixing equations being used are easily understood, and the correct mixing model is chosen for any given problem. Information from a variety of sources is collated to provide the user with a book which contains all the important elements: the theory; the models and solution methods for important river mixing problems; and the methods for determining mixing coefficients. Guidance is given when making rapid calculations for important mixing problems, and recent progress in the understanding of vertical and transverse mixing is discussed. The emphasis is placed on simple models which are invaluable for making rapid and relatively inexpensive appraisals of a mixing problem, although the more complex models, which may be used once a preliminary analysis has been completed, are also described. Covering all the key elements, River Mixing is essential reading for practising engineers, research scientists and technical managers of water resources.

Understanding and being able to predict fluvial processes is one of the biggest challenges for hydraulics and environmental engineers, hydrologists and other scientists interested in preserving and restoring the diverse functions of rivers. The interactions among flow, turbulence, vegetation, macroinvertebrates and other organisms, as well as the transport and retention of particulate matter, have important consequences on the ecological health of rivers. Managing rivers in an ecologically friendly way is a major component of sustainable engineering design, maintenance and restoration of ecological habitats. To address these challenges, a major focus of River Flow 2016 was to highlight the latest advances in experimental, computational and theoretical approaches that can be used to deepen our understanding and capacity to predict flow and the associated fluid-driven ecological processes, anthropogenic influences, sediment transport and morphodynamic processes. River Flow 2016 was organized under the auspices of the Committee for Fluvial Hydraulics of the International Association for Hydro-Environment Engineering and Research (IAHR). Since its first edition in 2002, the River Flow conference series has become the main international event focusing on river hydrodynamics, sediment transport, river engineering and restoration. Some of the highlights of the 8th International Conference on Fluvial Hydraulics were to focus on inter-disciplinary research involving, among others, ecological and biological aspects relevant to river flows and processes and to emphasize broader themes dealing with river sustainability. River Flow 2016 (extended abstract book 854 pages + full paper CD-ROM 2436 pages) contains the contributions presented during the regular sessions covering the main conference themes and the special sessions focusing on specific hot topics of river flow research, and will be of interest to academics interested in hydraulics, hydrology and environmental engineering.

Of all the books written about the problems of sustainable development and environmental protection, Sustainable Development: Science, Ethics, and Public Policy is one of the first to examine the role of science, economics and law, and ethics as generally applied to decision making on sustainable development, particularly in respect to the recommendations contained in Agenda 21. Specifically, the book examines the role, capabilities, and certain strengths and weaknesses of these disciplines and their ethical implications in the context of sustainable development problems. Such an analysis is necessary to determine whether sustainable development problems create important new challenges and problems for government so that, where appropriate, new tools or approaches may be designed to overcome limitations or take advantage of the strengths of current scientific, economic and legal capabilities. Audience: Environmental professionals, whether academic, governmental or industrial, or in the private consultancy sector. Also suitable as an upper level text or reference.
