Tybee Island is a barrier island located immediately south of the mouth of the Savannah River. Natural processes and modifications introduced by man have promoted a complex history of shoreline evolution which has important implications for other 'developed' barrier islands. Periodic reorientation of the shoreline has caused a history of localized erosion and localized protection efforts. This has resulted in the sequential construction of numerous groins, seawalls, and revetments, in addition to periodic beach nourishment activities. Each of these efforts is analyzed and presented along with a review of the various engineering and geologic studies which have been conducted over the last 50 years. The current status of erosion and erosion control efforts is presented. Recommendations are also offered. Keywords: Beach erosion; Shore protection; Coast changes; Coastal engineering.
The wide sandy beaches, quiet maritime forests, and vast Spartina marshes of the natural Georgia coast create a most spectacular, albeit gentle, Southern beauty. Casual visitors and longtime residents alike have been charmed by this special place. Living with the Georgia Shore provides an essential reference and guide for residents, visitors, developers, planners, and all who are concerned with the conditions and future of Georgia's coastal zone. Recounting the human and natural history of the islands, the authors look in particular at the phenomenon of coastal erosion and the implications of various responses to this process. In Georgia, as elsewhere in the United States, the future of the shore is in doubt as recreational and residential development demands increase. This book provides guidelines for living with the shore, as opposed to simply living on it. The former requires planning and a wise choice of property or house site. The latter ignores the potential hazards unique to coastal life and may make inadequate allowance for the dramatic changes that can occur on any sandy ocean shore. Living with the Georgia Shore includes an introduction to each of the Georgia isles, an overview of federal and state coastal land-use regulations, pointers on buying and building at the shore, a hurricane preparation checklist, a history of recent hurricanes in Georgia, an extensive annotated bibliography, and a guide to government agencies and private groups involved in issues of coastal development.
The coastal zone is subject to strong pressures from a large number of users. Populations are migrating to it in large numbers. Industry wants to exploit it for its space, water and manpower. Aggregate miners want to exploit mineral resources and health centers are multiplying. It is a favorite area for tourism and recreation worldwide. The zone can boom economically. However, coastlines are progressively receding worldwide, making the zone fragile, vulnerable, and unstable. The book presents methods of coastal protection and beach restoration and offers solutions to the various problems.
An overview of the engineering projects undertaken by the U.S. Army Corps of Engineers from 1850-1984 along the Savannah River.
This manual provides guidance for the design of beach fill projects intended to protect coastal development from coastal storm waves and erosion. This manual applies to HQUSACE elements, major subordinate commands, districts, laboratories, and field operating activities having responsibility for design, construction, and operation of civil works projects within the nearshore coastal region. This manual discusses the data needed, identifies data sources, and discusses parameters and methods applicable to beach fill design procedures. The importance of borrow material characteristics and procedures for adjusting the fill quantity to account for differences between natural beach material and borrow material are presented. Monitoring needs prior to, during, and following construction are also discussed.
Over the last 100 years, sea level has risen approximately 12 centimeters and is expected to continue rising at an even faster rate. This situation has serious implications for human activity along our coasts. In this book, geological and coastal engineering experts examine recent sea level trends and project changes over the next 100 years, anticipating shoreline response to changing sea level and the consequences for coastal development and uses. Scenarios for future sea level rise and several case studies are presented.
