Proceedings of a seminar on concrete armor units, held in Vicksburg, Mississippi, November 7-8, 1989. Hosted by the Waterways Experiment Station, Coastal Engineering Research Center, U.S. Army Corps of Engineers. Sponsored by Rubble Mound Structures Committee of the Waterway, Port, Coastal, and Ocean Engineering Division of ASCE. This collection contains 21 papers assessing the design, analysis, and hydraulic model testing of concrete armor units used in coastal rubble mound structures.Papers analyze prototypes of concrete armor units and current design procedures. Research needs are identified.

Abstract: "This proceedings is the record of a workshop hosted by the Coastal Engineering Research Center. The objective of the workshop was to review the current state of knowledge of the structural strength of breakwater concrete armor units and to discuss past and proposed measurements of the structural forcing and response. The invited participants represented a purposeful mix of coastal engineers, structural engineers, concrete specialists, and laboratory and field experimenters. Both researchers and engineers involved in the design and construction of rubble-mound breakwaters participated."

Laboratory physical models are a valuable tool for coastal engineers. Physical models help us to understand the complex hydrodynamic processes occurring in the nearshore zone and they provide reliable and economic engineering design solutions.This book is about the art and science of physical modeling as applied in coastal engineering. The aim of the book is to consolidate and synthesize into a single text much of the knowledge about physical modeling that has been developed worldwide.This book was written to serve as a graduate-level text for a course in physical modeling or as a reference text for engineers and researchers engaged in physical modeling and laboratory experimentation. The first three chapters serve as an introduction to similitude and physical models, covering topics such as advantages and disadvantages of physical models, systems of units, dimensional analysis, types of similitude and various hydraulic similitude criteria applicable to coastal engineering models.Practical application of similitude principles to coastal engineering studies is covered in Chapter 4 (Hydrodynamic Models), Chapter 5 (Coastal Structure Models) and Chapter 6 (Sediment Transport Models). These chapters develop the appropriate similitude criteria, discuss inherent laboratory and scale effects and overview the technical literature pertaining to these types of models. The final two chapters focus on the related subjects of laboratory wave generation (Chapter 7) and measurement and analysis techniques (Chapter 8).
