In which situation would beach nourishment be a good solution to issues caused by beach erosion?
1. a beach experienced sand loss due to currents and waves.
2 a beach experienced a recent increase in its plant population
3. a beach experienced a recent decrease in the sea turtle population.
4. a beach experienced massive sand loss after a recent hurricane.

Explanation:

Beach nourishment is carried out in beaches which loose sand due to erosion. The erosive sea waves and currents take away the beach sand and lower down the beach level thereby making it unattractive from the view point of tourism and recreation.  

For nourishing the beaches, sand is brought from nearby dredging areas and poured into the beaches. Also a buffer is created by these sand deposits to prevent the erosion.
