If a waves swash is bigger than its backwash it is… 

• Surging 

• Depositional 

• Longshore drift 

• Erosional 

What is longshore drift?

• When a wave’s backwash is stronger than its swash resulting in the erosion of the beach 

• When sand is moved diagonally along the beach due to natural wave action 

• When boats are caught in waves current and are swept along the coast
