Hiya. A swash aligned beach is where the swash of the waves (movement of the waves coming onto the beach) is at a vertical angle (90 Degrees). A drift aligned beach is where the swash is pushed out at an angle (diagonal motion)

Hope this helps. :D

Drift aligned beaches are produced where waves break at an angle to the coast. The swash therefore occurs at an angle but the backwash runs perpendicular to the beach. As a result, material is transported along the beach via longshore drift. Swash aligned beaches (e.g. Hell’s Mouth) are produced where the waves break in line (parallel) with the coast. Swash & backwash movements move material up and down the beach producing the aforementioned beach profile features. Swash aligned beaches are smoothycurved, concave beaches. The beach face is orientated parallel to the fronts of the dominant waves. Beaches which face the waves are termed swash aligned.
