What conclusion did the researchers from university of california san diego reach regarding the best type of material to use for beach nourishment?

a. boulders should be placed near the water's edge to prevent the current from taking the new sand out to the ocean.

b. sandy areas of a beach should alternate with cement areas to prevent erosion.

c. large, coarse grains of sand should be used since they remain on the beach longer.

d. sand mixed with soil should be used to promote plant growth and prevent erosion.

The researchers from University of California San Diego can conclude the Large, coarse grains of sand should be used since they remain on the beach longer about the best type of material to use for beach nourishment

Option C

Explanation:

Beach nourishment is adding excessive sand or sediments to a beach. It is used to stabilize the shore line. If any artificial buildings or structures are used it will spoil the beach look. Due to rising sea levels we have this problem of the sea level rising where water comes too close to the living areas.

Large and coarse grains of sand should be used as they stay longer and help prevent erosion. Threatening storms and natural disasters deplete the coastal line which seeks an immediate intervention to preserve the coastal areas.
