River restoration projects are designed to recreate functional characteristics within a context of physical stability. They tend to focus on the development and application of geomorphic principles for river restoration design. Due to different models obtaining different results on the same problem, incomplete or absent data, and climatic/social/cultural changes, the designers and managers of such projects frequently face high levels of uncertainty.This book will provide a systematic overview of the issues involved in minimizing and coping with uncertainty in river restoration projects. A series of thematic sections will be used to define the various sources of uncertainty in restoration projects and how these show at different points in the life cycle (design, construction and post-construction phases) of restoration projects. The structure of the book will offer a rational theoretical analysis of the problem while providing practical guidance in managing the different sources of uncertainty. A wide range of case studies will be included from Europe, North America and Australasia

The original edition of this volume was published by Seaby thirty-six years ago and has been through three revisions (1970, 1974, and 1981). The only one-volume price guide to the coinage of Republican and Imperial Rome. It is an indispensable listing of all major types of gold, silver and bronze, issued over some seven hundred and fifty years by the greatest militaristic state the world has ever known. Over 4,300 coins are included with detailed description and valuations and all major and minor personalities are listed by means of their portrait coins. This fourth revised edition takes note of recent work in the field, especially that of Professor Michael Crawford.
