The purpose of this book is to familiarize engineers and contractors with various established methods of low cost shore protection. It is written for the individual who is knowledgeable in general civil engineering design and construction, but not a specialist in coastal engineering or shoreline protection. The methods described in this book are usually appropriate for use only in sheltered waters. That is, they are generally not intended for open coast sites where they would be exposed to the undiminished attack of large oceanic waves.
