Definition of Swash:
Up and down propagation of bores formed after collapse of waves on the beach. Swash is the decelerating uprush phase and backwash is the accelerating downrush phase.
This is the common definition for Swash, other definitions can be discussed in the article
On dissipative coasts swash processes are dominated by infragravity waves.
