How is the beach replenished of sand?

Question:
How is the beach replenished of sand?
Answer:

Sand is dredged from a licensed area of seabed, for example, to the South East of the Isle of Wight. It is brought by dredger close to the section of beach where it will be deposited. The sand is then pumped through a long pipe on to the beach. The sand is mixed with water to assist it being pumped. As the mixture exits the pipe the water flows back in to the sea leaving the new sand behind. The beach is then levelled using bulldozers.
