Benthos as a key driver of morphological change in coastal regions [PDF]

Earth Surface Dynamics
Benthos has long been recognized as an important factor influencing local sediment stability, deposition, and erosion rates. However, its role in long-term (annual to decadal scale) and large-scale coastal morphological change remains largely speculative.
