Shingle beach nourishment
Fixed structures on mobile shingle shores have a number of drawbacks which
led in the 1970s to beach nourishment as being an acceptable alternative. Three
reasons can be cited:
- Beaches are better dissipaters of energy, absorbing rather than reflecting
the wave attack;
- Introducing additional material can reduce the potential for downdrift erosion;
- A wide stable beach is a local amenity (Coates
et al. 2001).
Examples of shingle nourishment schemes include:

Guidance: Shingle nourishment is an important method of beach
restoration. A principal requirement is an understanding of the beach
morphology. This is essential not only in relation to developing a sustainable
coastal defence system in the long term, but also in ensuring that there
is minimal impact on amenity and/or environmental interests in the area.
