Types of Shoreline Management
Effective coastline management is essential for building resilience to boat wakes and climate change impacts, such as sea-level rise, increased storm intensity, and temperature fluctuations. It is projected that 33% of shorelines in the US will be hardened by 2100 (NOAA, 2023). Proper management involves a strategic combination of green and grey infrastructure to ensure the safety of residents and the preservation of property. Sustainable considerations balance the needs of communities with environmental conservation and are crucial for maintaining the health of coastal ecosystems. A balanced and integrated approach that considers both natural and engineered solutions is often the most effective strategy for long-term coastal resilience.
Green Techniques
Living shorelines are sustainable, nature-based solutions designed to protect coastal areas from erosion and enhance ecological health. Unlike traditional hard structures such as seawalls or bulkheads, living shorelines incorporate vegetation, sand, and other organic materials to create a resilient buffer between land and water.
Erosion Control
Provides effective erosion control, safeguarding coastal areas from the impacts of storms and tidal action.
Water Quality Improvement
The vegetation in living shorelines acts as a natural filter, improving water quality by trapping sediments and pollutants.
Biodiversity
By creating a more natural habitat, living shorelines support a diverse array of plant and animal species, contributing to a healthier and more resilient ecosystem.
Aesthetic Appeal
Enhances the aesthetic value of coastal areas, creating picturesque landscapes for recreation and appreciation.
Grey Techniques
Grey infrastructure involves conventional, engineered structures such as seawalls, bulkheads, and levees. These structures are designed to control water flow, prevent erosion, and protect human development from natural forces. Typically, grey infrastructure involves rigid materials such as concrete or steel.
Erosion Control
Provides immediate and effective protection against erosion and flooding.
Wave Energy Reduction
Often used in densely populated areas where the focus is on safeguarding property and infrastructure.
