for “Debris-flow Hazards and Related Phenomena”

Citation by Susan H. Cannon and William H. Schulz It is with great pleasure that we present the 2009 E.B. Burwell, Jr. Award to Matthias Jakob and Oldrich Hungr for their book Debris-flow Hazards and Related Phenomena. Landslides are among the most deadly and damaging of Matthias Jakob Oldrich Hungr geological processes, and most losses from landslides are from debris BGC Engineering University of British Columbia flows and the related phenomena, hyperconcentrated flows and lahars. These phenomena can be dangerous because of their great mobility, high impact forces, and large inundation areas, as well as covered and the organization by which it is presented. The book the difficulties associated with predicting their location, size, and begins with an overview of the debris-flow problem, a synthesis of time of occurrence. Recognition of hazards posed by debris flows terminology and definitions used worldwide, and a presentation of the increases with each deadly event, and thus study of debris flows has historical significance of debris flows and their understanding. These flourished in recent decades. However, results from important work introductory chapters provide the reader with a strong foundation for have remained scattered throughout various journal publications, what is to come and are aptly followed by chapters describing the most conference proceedings, and consulting reports. Fortunately for all of advanced knowledge on slope failures that may result in debris flows, us in the field, Drs. Jakob and Hungr recognized the necessity for a mechanisms resulting in debris-flow mobility, and debris-flow growth concise presentation of the state-of-the-science knowledge of debris- by entrainment. As the reader has then developed an understanding flow hazards and expended considerable effort to compile, partly write, of debris-flow initiation and movement, the book presents chapters and edit such a volume. The result is Debris-flow Hazards and Related describing the related phenomena of hyperconcentrated flow, Phenomena. subaqueous debris flows, and volcanic debris flows (lahars). The As experts in debris-flow science, Drs.
