Coastal Groins and Nearshore Breakwaters
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers No. 6. This book provides guidance for the design and placement of beach stabilization structures, specifically groins, nearshore breakwaters, and submerged sills. Groin dimensions--such as height, length, spacing, and permeability--and their effects on a groin's functional performance are examined, along with the use of physical and mathematical models to evaluate designs. Topics include: various design factors; the effect of breakwaters on nearshore circulation; wave conditions in the breakwater's lee; longshore transport; onshore-offshore transport; and construction and post-construction activities. Because the design of beach stabilization structures requires analysis of the wave, current, and longshore transport environments as well as the coastal processes at a project site, this manual can only provide general guidance and design concepts in the area of beach stabilization. The manual also includes a compilation of the advantages and disadvantages of the various types of beach stabilization systems.
Soft Shore Protection
Global warming, melting polar caps, rising sea levels and intensifying wave-current action, factors responsible for the alarming phenomena of coastal erosion on the one hand and adverse environmental impacts and the high cost of 'hard' protection schemes, on the other, have created interest in the detailed examination of the potential and range of applicability of the emerging and promising category of 'soft' shore protection methods. 'Soft' methods such as beach nourishment, submerged breakwaters, artificial reefs, gravity drain systems, floating breakwaters, plantations of hydrophylous shrubs or even dry branches, applied mostly during the past 20 years, are recognised as possessing techni...
Low Cost Shore Protection
This report presents low cost ways for the shoreline property owner to control or slow down shoreline erosion. Beach erosion processes were described as well as the effects of breakwaters, groins, beach fill, revetments etc. Each method of shore protection is described in terms of shoreforms and situations where it can be used sucessfully, how it protects the shore, its advantages and disadvantages, and its general design features and construction materials.

Coastal Defences
Coastal Defences aims to present the broad spectrum of methods that engineers use to protect the coastline and investigates the sorts of issues that can arise as a result. The first section of the book examines 'traditional' hard techniques, such as sea walls and groynes, whilst the second looks at the more recent trend of using techniques more sympathetic to nature. By looking at each of the main methods of coastal protection in detail, the book investigates the rationale for using each method and the consequent management issues, presenting a case for and against each of the techniques.
Groynes in Coastal Engineering
This publication is bases on a report of Phase 1 of a research project which was undertaken to provide information on the state of groyne systems and to identify problems, select appropriate study areas and evolve terms of reference for the main studies to be undertake subsequently.
Introduction to Coastal Dynamics and Shoreline Protection
"Provides an integrated approach to coastal dynamics and shoreline protection, aided by the use of specific case studies" -- Back cover.
Pitfalls of Shoreline Stabilization
At the coast all is not what it seems. Decades of beachfront development have seen a variety of efforts to stabilize the shoreline to protect ill-placed beachfront property, both from shoreline erosion and from storm damage. Both of these problems become increasingly critical in a time of rising sea level. Many natural beaches are backed by sea walls, while others have been transformed by whole series of groynes, offshore breakwaters and a plethora of other schemes. Many recreational beaches are actually artificial replicas of the real thing, emplaced to protect badly placed infrastructure and maintained only through ongoing costly beach nourishment. However, all of these attempts to stabili...
