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...

Volume II now extends coverage of the Imperial series from Nerva, the 'thirteenth Caesar' and first of the 'Adoptive' emperors, down to the overthrow of the Severan dynasty in 235.
