Which of the following is a potential drawback of using jetties to prevent beach erosion?

Jetties block boats from being able to enter harbors.

Building jetties are more expensive than soft beach management strategies.

Beach erosion may increase on the downdrift side of the jetties.

Jetties are not effective until plant life has time to grow.

On the up drift side of a jetty there is accumulation of sand while the opposite effect takes place on the down drift side. This erosion is caused by the jetty due to the lack of sand which is trapped on the other side. Ironically, Jetties,which are built to prevent erosion, end up causing more damage than providing a solution.

The potential drawback of using jetties to prevent beach erosion is beach erosion may increase on the downdrift side of the jetties. So, the correct option is C.

What do you mean by Jetties?

It is a type of structure that is extended into a sea, lake, or river to influence the tide, current, or to protect the harbor.

The structure of the jetty consists of an upside and a downside, the upside has a lot of sand, while on the downside more amount of water is found. This results in erosion where there is a lack of sand. But the purpose for which the jetties have been built creates a problem (disbalance) rather than preventing the erosion.

Therefore, the potential drawback of using jetties to prevent beach erosion is beach erosion may increase on the downdrift side of the jetties.
