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).

Peru’s fisheries are in crisis as overfishing and ecological changes produce dramatic fluctuations in fish stocks. To address this crisis, government officials have claimed that fishers need to become responsible producers who create economic advantages by taking better care of the ocean ecologies they exploit. In Coastal Lives, Maximilian Viatori and Héctor Bombiella argue that this has not made Peru’s fisheries more sustainable. Through a fine-grained ethnographic and historical account of Lima’s fisheries, the authors reveal that new government regimes of entrepreneurial agency have placed overwhelming burdens on the city’s impoverished artisanal fishers to demonstrate that they are responsible producers and have created failures that can be used to justify closing these fishers’ traditional use areas and to deny their historically sanctioned rights. The result is a critical examination of how neoliberalized visions of nature and individual responsibility work to normalize the dispossessions that have enabled ongoing capital accumulation at the cost of growing social dislocations and ecological degradation. The authors’ innovative approach to the politics of constructing and degrading coastal lives will interest a wide range of scholars in cultural anthropology, environmental humanities, and Latin American studies, as well as policymakers and anyone concerned with inequality, global food systems, and multispecies ecologies.

Coastal zones exemplify the environmental pressures we face: their beauty attracts settlement, they offer potential for diverse economic activities, and they are sensitive natural habitats for important species, as well as providing a range of ecosystem services. They are also extremely vulnerable to the vicissitudes of climate change, which include rising sea levels and changes in extreme events such as storms. With large populations living in coastal and estuarine cities facing the ongoing threat of inundation, coordinated management is essential, especially as coastal zones form a linked system in which piecemeal, uncoordinated management could be counterproductive.
