This timely book is about how to design alternatives to reduce coastal flood and wave damage, erosion, and loss of ecosystems facing an unknown future of sea level rise. The latest theories are interlaced with applied examples from the authors' 48 years of experience in teaching, research, and as a practicing, professional engineer in coastal engineering. The design process take into consideration all the design constraints (scientific, engineering, economic, environmental, social/political/institutional, aesthetic, and media) to meet today's client needs, expectations, and budgets.
