Groundwater Hydrology David Keith Todd J o h n W i l e y , C h i c h e s t e r a n d N e w Y o r k , 1980, 2 n d E d n , 535 p p . The purported purpose of this monograph is the presentation of the 'fundamentals of groundwater hydrology in a manner understandable to.those most concerned with such knowledge'. The author achieves this objective in a nicely prepared book that should adorn the shelf of anyone actively working in the field of groundwater hydrology. The material is presented at an elementary level and should be readily understood by anyone with a modest exposure to elementary courses in geology and calculus. The book presents a comprehensive overview of groundwater hydrology. It is replete with an extraordinary list of references which are appropriately cited in the text. The book is subdivided into fourteen chapters. The subjects considered are: groundwater occurrence and movement, well construction and hydraulics, water table fluctuations, groundwater investigations and management, groundwater quality, and artificial recharge. The material is presented primarily from a qualitative perspective but the author does consider some fundamental theory when it is necessary such as in his discussion of well hydraulics. Because of the scope of the monograph the treatment of each subject is necessarily somewhat limited. Thus, this book would be useful to anyone interested in an overview of the subject but of lesser utility to the specialist. This work compliments more theoretical texts and could be used as supplementary reading in a course in groundwater hydrology.

Estuarine and Wetland Processes Edited by Peter Hamilton and Keith B. Macdonald Plenum

P r e s s , N e w Y o r k , 1980, 653 p p .

This volume originated from a workshop held in June 1979 in New Orleans, sponsored by the Environmental Laboratory of the Waterways Experimental Station, Vicksburg. The stated objective is to describe the ecology of estuaries and their surrounding wetlands with particular emphasis given to the numerical modelling of the fundamental hydrodynamics, mixing processes, sediment transport and biological and chemical processes. Although the 25 separate contributions include several stateof-the-art reviews, the majority of the contributions deal with specific case-histories. The orientation of the latter is directed towards their original presentation and, in consequence, the applications deal almost exclusively with locations along the south-east coast of the USA. Furthermore, about 75~o of the studies are confined to the modelling of hydrodynamics and mixing processes only. Interest in these case-histories will generally be limited to fellow-practitioners and, even then, the narrow geographic confines considered limit the usefulness of these contributions. The review articles are to be recommended, particularly as they start from a most basic level before proceeding to the finer points of current research. The subjects of these review papers include: (i) turbulent processes in estuaries, (ii) hydrodynamic modelling of estuaries, and (iii) the ecology of salt marshes. The book is notably well-bound and the presentations, in a uniform type, are sensibly free from minor errors. In summary, this is not a volume to be read from cover to cover but a reference manual for anyone engaged in, or contemplating, studies of this nature.

Adv. Water Resources, 1981, Volume 4, June

The substance of this compendium is the result o f a US Environmental Protection Agency sponsored workshop which was organized to evaluate the state of the science {or rather the art) of water quality modelling, and to make specific recommendations for future efforts. A cross-section of experts from government, academia, industry, and private practice were assembled in West Point, New York on 7-9 March, 1979. The list of particiPants could easily provide a basis for a 'Who's Who in Water Quality Modeling'. In the same vein as society has coined expressions such as "a gentleman's gentleman', one might label this manuscript as one produced by "the modelers' modelers'. Anyone who has worked with water quality models should be interested in reviewing this report. This event provided the opportunity for some of the foremost modellers to take time out for a bit of soul searching and self-analysis. As expected such an occasion might adjourn with more questions than were evident at the outset, but equally true is that the science and the profession are undoubtedly the better for it. Basic issues discussed include models in decision-making, model data bases, modelling framework [including time and space scales, kinetic detail and cost effectiveness), parameter estimation, measures of verification and use of models as projection tools. Workshop committee reports present the state of the art and recommendations in the areas of wasteload generation, transport systems, salinity.TDS, dissolved oxygen,/ temperature, bacteria/visur, eutrophication, and hazardous substances. In addition, twenty-five papers on various issues related to the committee reports are presented by individuals. The workshop recommendations stressed the need for greater communication between decision making, modelling and data collection, particularly for post-audit data collection programs and subsequent model studies to verify previous model projections.

Finite Elements in Water Resources CML

This book contains the edited proceedings of the 3rd International Conference on Finite Elements in Water Resources held at the University of Mississippi, in May 1980. The book contains approximately 90 papers presented at the conference. Topics covered include: groundwater and seepage, transport phenomena; viscous flows: river, lake and ocean modelling; sedimentation processes: finite element techniques. The finite element method has become, because of its versatility, one of the most important tools for modelling physical problems - - particularly those with true irregular geometries and heterogeneous physical properties which are common to all realistic water resources systems. The conference attempted to present a state of the art of finite elements in water resources and consequently 40 of the papers contained in the proceedings were presented by distinguished invited speakers. The other 50 papers were carefully selected to
