Breakwaters and closure dams\nThis book is primarily a text book for graduate students in Civil Engineering. It places the developments in their historic perspective, at least when this contributes to better understanding.\nThe book builds on a variety of courses on subjects such as fluid mechanics, hydraulic engineering, coastal engineering and bed, bank and shore protection, design process, and probabilistic design. Many subjects are refreshed briefly.\nAt first sight it seems strange to combine the design of two rather dedicated types of structures with distinctly different purposes, however from an educational point of view this is not so. In both cases the design process requires that due attention should be paid to:\nthe functional requirements,\nthe various limit states to which a structure will be exposed in relation to the requirements,\nthe various limit states that occur during construction phases,\nthe relation between these limit states and the occurrence of certain natural conditions.\nThe differences between closure dams and breakwaters will enable us to focus attention on the above mentioned considerations. In addition to this, there are also quite a number of similarities. In this respect, the book deals also with construction materials, such as quarry stone, concrete blocks and caissons, which are widely used in both types of structures. The same applies to a wide range of construction equipment, both floating and rolling, and, last but not least, the interdependence between design and construction.\nContents: 1. Introduction 2.
