Understanding Coastal Erosion and Solutions

Front

What is coastal erosion?

Back

Coastal erosion is the process by which coastlines are eroded by the action of waves, currents, tides, and human activities, leading to the loss of land.

Front

What are the main causes of coastal erosion?

Back

The main causes of coastal erosion include wave action, tidal forces, ocean currents, and human activities such as construction and deforestation.

Front

What is the projected increase in global mean sea level in 50 years according to NOAA?

Back

At least 1 foot.

Front

What is a breakwater?

Back

A breakwater is a structure built parallel to shorelines to protect the coast from the impact of waves.

Front

What is the primary reason humans are fascinated with the coast?

Back

The coast is where the ocean meets the land.

Front

What role do waves play in coastal erosion?

Back

Waves are the primary force driving coastal erosion, as they continuously impact the shoreline, wearing away rocks and sediment.

Front

What is beach nourishment?

Back

Beach nourishment is a coastal management strategy that involves adding sand or sediment to beaches to combat erosion and increase beach width.

Front

What does 'retreat' mean in coastal management?

Back

Retreat refers to the strategy of moving development away from the coast to protect it from erosion.

Front

What are seawalls?

Back

Seawalls are structures built parallel to the shoreline to protect coastal areas from wave action and erosion.

Front

What is the difference between groins and breakwaters?

Back

Groins are structures built perpendicular to the shoreline to trap sand and prevent erosion, while breakwaters are built parallel to the shore to protect against wave action.
