structures. These on-shore phenomena dictate the crest élévation and the
seaward slope of Coastal structures.
The phenomenon of scour is an important failure mechanism of structures in Coastal and marine environment, the causes and effects of which
are discussed in the chapter on Scour around marine structures. The
various parameters that lead to scour and different types of scour formation
are discussed herewith to notify the engineers regarding the importance in
design against scour failure. In addition, a brief introduction to pipelines
and scour related to pipelines along side scour protection and bed shear
stresses are detailed.
The understanding of various concepts in Coastal engineering is essential
to dictate appropriate design principles. The chapter on Design of Coastal
structures discusses the various methods of computing wave forces induced
on structures due to breaking and non-breaking waves. The design principles and formulation of various layers of rubble mound structures are
detailed with examples. In addition the design principles of retaining structures, sheet piles, marine piles, etc. are briefed.
This book would fulfill its wholesome objectives and become complété
only if the concept of physical and numerical modeling are discussed.
Thus at the last leg, the various methods and techniques for assessing the
performance of Coastal structures are briefly presented. Any proposed protection measure can be potentially evaluated for their functioning at calm
or extreme events and possible failure mechanisms using the techniques
discussed through laboratory measurements.
The references included in this book are vast and extensive, yet they
would furnish more exhaustive topics pertaining to this field of study.
