文摘

A model is developed to describe aggregate layer formation by delayed settling. Depth-dependent settling velocity is formulated using laboratory observations. Layer intensity and sharpness depend on aggregate settling behavior and turbulence. Model predicts layers formed by delayed settling that are asymmetrical and peaky. Results provide predictive ability for layer formation by delayed settling in the field.
