sediment cell

A sediment cell is a specific segment of the coastline where sediment, such as sand and gravel, moves within a closed system. Each cell has natural boundaries, like cliffs or river mouths, that trap sediment and prevent it from drifting to adjacent areas. This process is important for coastal stability, as it helps build and maintain beaches and prevents erosion. Understanding sediment cells is crucial for effective coastal management and protecting shorelines from the impacts of human activity and natural changes, such as storms and sea level rise.
