Question 14
Which one of the following would NOT be a likely effect of constructing a pair of JETTIES at a harbor channel entrance to the open ocean along a beach-lined coast?
Decreased sand deposition in the channel entrance.
Increased beach erosion on the down- (longshore) current side of the jetties.
Increased beach sand deposition on the up- (longshore) current side of the jetties.
Increased erosion of beach sand on the up- (longshore) current side of the jetties.
Decreased sand deposition in the channel entrance.
Increased beach erosion on the down- (longshore) current side of the jetties.
Increased beach sand deposition on the up- (longshore) current side of the jetties.
Increased erosion of beach sand on the up- (longshore) current side of the jetties.
Explanation / Answer
Answer: Increased erosion of beach sand on the up- (longshore) current side of the jetties.
Increased erosion of beach sand on the up- (longshore) current side of the jetties would NOT be a likely effect of constructing a pair of JETTIES at a harbor channel entrance to the open ocean along a beach-lined coast.
Jetties can be described as the pair of long groins that protect harbor channel from sedimentation, this is because of size, jetties can completely cut off longshore sediements transport. Here sum of downcurrent erosion and problem of upcurrent deposition is greater than groins.
