Question

In 3–5 sentences, construct an argument for why beach nourishment is or is not a viable strategy to manage beach erosion.

Answer 1

Answer:

describes a process by which sediment, usually sand, lost through longshore drift or erosion is replaced from other sources. A wider beach can reduce storm damage to coastal structures by dissipating energy across the surf zone, protecting upland structures and infrastructure from storm surges, tsunamis and unusually high tides.[citation needed] Beach nourishment is typically part of a larger coastal defense scheme. Nourishment is typically a repetitive process since it does not remove the physical forces that cause erosion but simply mitigates their effects.

Answer 2

Answer:

Compatibility issues, No exact volume calculation, high cost of construction etc

Explanation:

Beach nourishment is not a viable strategy to manage beach erosion because of the following reasons -

1. It is very difficult to exactly calculate or evaluate the amount of sand volume that is to be brought from nearby borrowing area

2. The cost of construction and maintenance is extremely high

3. Though it is one of the environment friendly method to cater sand beach losses, yet it disturbs the ecology by disturbing the native flora and fauna of the borrowing land

4. It also causes compatibility issue. The sand transported from other areas may have varying characteristics as compared to the sand in the areas where beach nourishment is to be done. This difference may cause higher level of erosion the next time.
