Book Description
Submerged breakwater is an off shore breakwater, with its crest at or below the SWL, used for creation of protected area of water or for protection of coastal structures and beaches from damage of erosion caused by wave action. Reef breakwaters are coast parallel structures built with an objective of reducing the wave action on the beach by forcing wave breaking over the reef. The present work involves the experimental study on submerged breakwater made of concrete cube armour of varying sizes. A stable trapezoidal submerges breakwater having a slope of 1V:1.75H with a crest width (B) of 0.1m and height (h) of 0.25m is constructed, with homogenous pile of concrete cubes. Two such reef models are designed with concrete cubes weighing 45g and 50g as given by various design criteria. The models are tested in water depth of 0.4m with varying wave heights (0.1m to 0.16m) and wave periods (1.5s to 2s). During the investigation the reduction in crest height, wave incident and transmission over submerged breakwater are observed and the stability parameters are analysed and studies.

Book Description
Numerical Models for Submerged Breakwaters: Coastal Hydrodynamics and Morphodynamics discusses the practice of submerged breakwaters, an increasingly popular tool used as a coastal defense system because of their amenity and aesthetics as compared to common emerged beach protection measures. The book is the perfect guide for experienced professionals who wish to keep abreast of the latest best practices or those who are entering the field and need a reference, explaining new and traditional numerical methodologies for designing submerged breakwaters and measuring their performance. In addition, the book provides case studies, examples, and practical methods for data selection and pre-processing, model setup, calibration, and analysis. Case studies and worked-out examples illustrate different concepts and methods Offers practical methods for Data Selection and Pre-Processing Provides simplified prediction tools for practical applications

Book Description
Report discusses results of full-scale laboratory tests for one emergent and three submerged breakwaters of sand-filled nylon bags on a sand bed which were subjected to severe wave conditions. Tests determined bag properties, effects of wave action on bag placement, and performance of bags and structures for various combinations of structure configuration and wave conditions. Changes in the sand bed at base of structures and wave attenuation by the breakwaters were also investigated. (Author).

Book Description
Coastal Environments: Problems and Perspectives display the impact of natural forces and processes on man and also the impact of man on the coastal environment. The exploitation of natural mineral resources, navigation and recreation activities are an integral part of the problems and perspectives of coastal environments. This volume highlights various processes, particularly sediment transport, coastal erosion and its management, landform evolution and resources of the coastal region. The case studies are presented under each section. The availability of comprehensive basic scientific data is vital for effective coastal zone management. There are sixteen papers together on coastal resources, coastal landforms, coastal erosion, sediment transport and dredging and all these add the scientific information for coastal zone management. The last section of the book comprises the papers on application of remote sensing in environmental studies and two assorted papers on surface run-off and flora of Gondwanaland. The causes for coastal erosion, the present scenario of erosion along Kerala and Karnataka coasts and the mitigation procedures have been explained in this book. The utility of seawalls and other protection structures in arresting coastal erosion has been discussed and debated in detail.
