The safe disposal of radioactive wastes by burial in deep geological formations requires long-term predictions of the future behaviour of the wastes and their engineered repository. Such predictions can be tested by evaluating processes analogous to those which will occur in a repository, which have been long active in the natural geochemical environment. The Pocos de Caldas Project is a comprehensive study of two ore deposits in Minas Gerais, Brazil, aimed at looking at uranium and thorium series radionuclide and rare-earth element mobility, the development and movement of redox fronts, and the nature of natural groundwater colloids. A multidisciplinary team of experts from 27 laboratories carried out a fully integrated study of the geology, geomorphology, hydrogeology, geochemistry, hydrochemistry and geomicrobiology of the two sites for nearly four years. This book contains 20 papers covering the detailed findings, with particular emphasis on their significance for radioactive waste disposal, especially on the use of the data in testing models of radionuclide movement. It will interest economic geologists, geochemists and performance assessment modellers involved in the geological disposal of radioactive wastes.

Within this monograph a comprehensive and systematic knowledge on shallow-water hydrodynamics is presented. A two-dimensional system of shallow-water equations is analyzed, including the mathematical and mechanical backgrounds, the properties of the system and its solution. Also featured is a new mathematical simulation of shallow-water flows by compressible plane flows of a special virtual perfect gas, as well as practical algorithms such as FDM, FEM, and FVM. Some of these algorithms have been utilized in solving the system, while others have been utilized in various applied fields. An emphasis has been placed on several classes of high-performance difference schemes and boundary procedures which have found wide uses recently for solving the Euler equations of gas dynamics in aeronautical and aerospatial engineering. This book is constructed so that it may serve as a handbook for practicians. It will be of interest to scientists, designers, teachers, postgraduates and professionals in hydraulic, marine, and environmental engineering; especially those involved in the mathematical modelling of shallow-water bodies.

Water resources exploitation has been regarded as a way of initiating economic development in many countries. Planning concepts are now changing. Thorough environmental studies, sociological and economic studies now preceed project formulation. Justification solely on the basis of benefit cost studies is no longer sufficient for many development agencies. The broader approach is introduced in this book, but the real emphasis is on the situation in and needs of developing countries.Some of the problems experienced in building water resources in developing countries are described in this book, and methods of solution based on the limited experience of the authors, are offered. These range from use of unbiased common sense, coupled with a close understanding of people's requirements, to a comprehensive computer simulated planning model. Some types of water resources development are described in more detail. These include irrigation, hydro electric power and rural water supply. Sections on socio-economics and human resource development are also included, as well as on data collection, and project planning. Lessons from the failure of multimillion dollar projects are not hard to come by, and examples and pointers which will assist future planners are given. Attention is paid to the need for aid to include training and to stimulate local economies. However big water projects appear, they cannot escape the effects of the rest of the country's economy. Attention is also drawn to environmental problems, particularly soil erosion, often caused by water resources development. The fact that water resources development cannot be carried out by engineers only, is recognized. The input of many professions, and vast experience, is needed. Drawn on international case studies, much of the material has been presented in postgraduate courses by the authors.

Glacigenic Sediments

This book aims primarily at providing those involved in fundamental or applied research in the fields of geology, geomorphology and hydrology with a systematic overview of glacigenic sediments. A generally applicable terminology is proposed which should facilitate communication between scientists from several fields. Also it should form a bridge between western and eastern "schools" dealing with Quaternary geology. Because the book is mainly devoted to depositional processes and the resulting deposits, the approach and the terminology followed in this book are obviously founded strongly on sedimentology, the geological discipline that deals specifically with these phenomena.The book will be helpful in describing the sediments involved, interpreting their genesis, establishing their extent and their mutual relationships, and thus in the reconstruction of the palaeogeographic development.The large list of references reflects the author's extensive search of the literature.

Soils on a Warmer Earth

The theme of this book is a far reaching one and should attract great interest, both in industrialized as well as in less developed countries. Although the question of climate change and its effects on soil productivity is overshadowed by so many current events, it is almost certain that this subject will remain on the international agenda for the years to come; not only as science and research are concerned but also in relation to development policies, agricultural policies and others, especially since poor, rich, developed and developing countries are equally threatened by these problems.

The development of environmentally sound groundwater resources has recently become a high priority throughout the world. Many countries are currently developing comprehensive regulations for the management of groundwater resources. Within this framework an assessment of renewable groundwater resources is one of the most important factors.This book is based on the author's many years of experience in the assessment of surface and subsurface water resources, field experiments and computer oriented work, in both developed and developing countries. An environmental approach is followed. Groundwater resources are seen as a part of the aquatic ecosystem in which not only geology but the whole lithosphere, vegetation, surface resources and atmosphere play an equally important role.Both simple and advanced models are presented, which can also be applied to complicated geological structures where standard groundwater models fail to operate. Conceptual and stochastic models are presented in a form which the reader can use as a guide for further model development - an approach much in demand in regions where many different features and a variety of data are available. Experimental work leading to the identification of groundwater resources is also broadly discussed.The book will prove valuable to students at university level, researchers, institutes, departments, and consultancies involved in water resources.

Asbestos minerals have novel properties which make them highly desirable for industrial use. While the health hazards of asbestos have long been recognized and are well documented in the medical literature, ecological and environmental research involving asbestos fibers has only been undertaken in the past 25 years and the significant deleterious effects of asbestos materials on soil and plant ecology has been much less well publicised.This book examines non-occupational exposure and environmental effects of asbestos relating to animal and plant growth in the natural environment. Major nutrient imbalances and excess concentrations of trace metals have been identified as main causes for the poor plant response. Given the complexity of the asbestos analysis and the extent of the problem, this book attempts to bring together the multitude of subjects pertaining to asbestos in the natural environment with the aim of contributing to a better understanding of the chemical characteristics of asbestos-rich materials and their effect on plant growth.
