Swash: Forward Water Movement
The term "Swash" defines the forward movement of sea water travelling up the beach surface after a wave has broken.
Wave Action Dynamics
Following a wave's break near the shore, the resulting surge of water moves up the beach slope. This process is known as the swash.
Swash vs. Backwash Distinction
Swash is distinct from the backwash, which is the subsequent backward flow of water down the beach, returning to the sea.
Option Evaluation
- Option 1 describes the backwash (backward movement).
- Option 2 refers to an oblique movement, not the standard definition.
- Option 3 accurately defines swash as the forward surge up the beach.
- Option 4 suggests sideward movement, which is incorrect.
