Beach Erosion

Erosion and Its Impact

• Approx. 70% of sandy coastlines in America experience erosion.
• Erosion leads to loss of beach area, affecting marine ecosystems and coastal properties.

Tourism and Beach Dynamics

• Beaches that generate tourism are primarily driven by recreational appeal, natural beauty, and accessibility.
• Erosion can deter tourists, impacting local economies reliant on beach activities.

Coastal Engineering and Sand Loss

• Coastal engineers employ beach nourishment to counteract natural sand loss.
• Beach nourishment involves adding sand to eroded beaches to rebuild them.

Historical Context of Miami Beach

• In the 1970s, Miami beach dramatically lost sand, affecting its viability for tourism.
• The beach was revitalized in the 1980s through extensive nourishment projects.

U.S. Coastal Protection Strategies

• Beach nourishment is the primary strategy used for protecting coastal properties from erosion.
• Nourishments typically need to be repeated every 2 to 8 years, on average.

Funding Aspects

• The federal government covers approximately 65% of the nourishment costs.
• The Army Corps of Engineers designs and approves these nourishment projects, prioritizing beaches based on potential loss of property value.

Community Equity and Nourishment

• Poorer communities often miss out on nourishment benefits due to funding priorities and economic disparities.
• A negative consequence of beach nourishment may include increased development pressure in vulnerable areas.

Development and Erosion Feedback Loops

• Expansive properties along nourished beaches can lead to a feedback loop, driving further development despite erosion risks.
• Beach nourishment is appealing primarily for its ability to maintain property values and tourism attractiveness.

Key True/False Statements

• True: Beach nourishment is the primary strategy used to protect coastal properties from erosion in the United States.
• True: The federal government pays for up to 65% of the cost of nourishment projects.
• True: Nourishments need to be repeated every 2 to 8 years, on average.
• True: Research indicates that areas with nourished beaches typically have homes about three times larger than those in non-nourished areas.
• True: Beach nourishment may mask or reduce the immediate impacts of coastal hazards without altering underlying natural erosion processes.
