Types of Coastal Management Strategies
Coastal management strategies encompass a range of approaches aimed at protecting and managing coastal areas. Two main types of strategies are commonly employed: hard engineering and soft engineering. Hard engineering strategies involve the use of structures and physical barriers to control coastal erosion and flooding.
Examples of hard engineering approaches include seawalls and groynes. Sea walls are vertical structures made of concrete or rock that are built along the shoreline to prevent wave action from eroding the land. Groynes, on the other hand, are wooden or concrete barriers that are constructed perpendicular to the shoreline to trap sediment and prevent it from being carried away by longshore drift.
Soft engineering strategies, on the other hand, focus on working with natural processes to manage coastal erosion and flooding. Beach nourishment is a common soft engineering approach that involves adding sand or sediment to eroded beaches to restore their natural profile and provide protection against wave action. Managed retreat is another soft engineering strategy that involves allowing the shoreline to naturally erode and retreat inland, while relocating human activities and infrastructure away from the coast.
Each coastal management strategy has its own set of advantages and disadvantages. Hard engineering approaches such as seawalls and groynes provide immediate protection against erosion and flooding. However, they can be expensive to construct and maintain, and may have negative impacts on the natural environment. Sea walls, for example, can disrupt natural sediment transport processes and lead to the erosion of adjacent beaches. Groynes can also cause beach erosion by trapping sediment on one side and depriving other areas of sediment supply.
Soft engineering strategies like beach nourishment and managed retreat offer more sustainable and environmentally friendly alternatives. Beach nourishment can enhance recreational value and provide habitat for coastal species. Managed retreat allows for the natural adaptation of coastal ecosystems to sea level rise and reduces the need for costly infrastructure maintenance.
However, these strategies may require ongoing monitoring and maintenance, and may not provide the same level of immediate protection as hard engineering approaches. Additionally, managed retreat may face challenges in terms of land availability and potential conflicts with existing land uses. Overall, the choice of coastal management strategy depends on the specific characteristics of the coastal area and the desired outcomes in terms of protection, sustainability, and environmental impacts.
