Throughout recorded history the great seaside centers of culture and commerce have relied upon safe harbors and the stability of their shores for survival. Today's coastline is of economical, social, cultural, and environmental value to communities and to nations. However, shorelines are dynamic and ephemeral places where erosion trends tend to dominate. Development along the shore places the desires of man to have a safe and stable home in direct opposition to the natural trends of nature to erode, transport, and deposit coastal lands. Human reaction to coastal erosion and flooding problems range from hardening the shore to continually replacing the lost material to limiting or stopping future development. Whatever management and engineering steps are taken should be determined as the result of a well-informed and logical process. Coastal management strategy, including the decision to incorporate shore protection works, should be based upon a clear understanding of the problem, site conditions, and socio-economic expectations.
Responding to Coastal Erosion and Flooding Damages
View complete article here. Coastal engineering is a highly specialized type of engineering that is designed to address both natural and man-made changes in coastal zones. A well-considered coastal engineering solution can provide the structural and non-structural protection against coastal changes, and can maximize beneficial effects while minimizing adverse impacts of potential solutions to problematic areas on a coast line. Coastal engineering involves an application of both physical science and engineering, and requires a thorough understanding of the area in question to fully understand the nature and complexity of the problem at hand. In the United States, there are over 84, miles of coastline, with approximately 41 percent of that coastline exposed to the open ocean, and the remainder sheltered by bays, estuaries and lagoons. The vast coastlines of the U. The wide variation in the types of American coastlines demonstrates the need for an in-depth study before undertaking a coastal engineering project.
As the sea level rises, the water depth increases and the wave base becomes deeper; waves reaching the coast have more energy and therefore can erode and.
