Sediment Cell
A conceptual framework dividing the coast into units where sediment circulation occurs with minimal cross-boundary movement, facilitating coastal management and understanding sediment dynamics.
Real World
England and Wales are divided into 11 major sediment cells by the Environment Agency; Cell 3 (Norfolk to Thames) underpins decisions about managing Happisburgh's rapid cliff erosion without disrupting downdrift beaches.
Exam Focus
Always identify sources, transfers, and sinks when describing a sediment cell — omitting one component typically loses a mark.
