Edge wave

Surface gravity wave fixed by refraction against a rigid boundary, often a shoaling beach

In fluid dynamics, an edge wave is a surface gravity wave fixed by refraction against a rigid boundary, often a shoaling beach. Progressive edge waves travel along this boundary, varying sinusoidally along it and diminishing exponentially in the offshore direction.^[1]
