Review of Scour Technology by George W. Annandale

This brand new book has been designed to provide insightful solutions to practical scour problems. It provides understanding of the interaction between turbulent flow and all kinds of materials, from vegetated cohesive soils to bedrock. Methods are presented to assess the erosive capacity of water and scour resistance of natural and engineered materials. The engineering management of scour problems is a unique contribution of this book. Other interesting features include the analysis of turbulent fluctuations, brittle fracture, geologic considerations of bedrock, rock bolts, and joint alterations, etc. The author shares 30 years of international experience in the analysis of scour, hydrology and hydraulics, and sediment transport. He proposes a unique approach to solve scour-related problems around bridge piers, below dams, in spillway chutes and energy dissipators, and in plunge pools and large water tunnels. His theoretical analysis hinges on stream power. The erodibilityindex method is explained in considerable detail. Throughout the text, the author emphasizes the design of effective scour protection countermeasures. The material is presented in 10 chapters; 1 scour management challenges; 2 engineering judgment; 3 scour processes; 4 material and fluid properties; 5 erosive capacity of water; 6 scour thresholds; 7 scour extent; 8 temporal aspects of scour; 9 engineering management of scour; and 10 case studies. The book also includes a brief preface with acknowledgments, a list of references, a useful list of symbols, and a combined author/ subject index. The book is very well illustrated and several photographs of large structures are quite impressive. The illustrations and frequent references to solving practical engineering problems permeate throughout the entire book. This book will be extremely useful to practicing civil engineers dealing with the topic of jet scour in plunge pools. This is a nice compendium of recent information and reflective discussion of the subject. It contains unique material on cohesive soils and on bedrock scour. What the author presents so well is a wealth of valuable information on the general subject of scour from vegetated channels to bedrock. The presentation includes relevant theory and understanding of rock and fluid mechanics. It also delves heavily into recent large-scale experiments carried out around the world. For instance, large-scale experiments such as those carried out at Colorado State University under Dr. James
