This book, Structure Design and Degradation Mechanisms in Coastal Environments, edited by Abdelkarim Ait-Mokhtar, provides a comprehensive exploration into the design, materials, characterization, and modeling necessary for creating safer and more resilient structures in coastal areas. The first edition, published on May 4, 2015, by Wiley-ISTE, delves into various aspects including porous and heterogeneous materials, concrete, moisture transfers within construction materials, and degradation caused by external attacks. It also discusses systems for monitoring the structural integrity of these environments and evaluating performance reliability as well as potential degradation scenarios in coastal protection systems.
