Escape of Pore Fluid from Consolidating Sediment
Cohesive sediment can be moved substantial distances as suspended solids in rivers, estuaries and coastal waters, until eventually insufficient energy is available to keep it in suspension and it is deposited. It may then consolidate and form an increasingly dense stable layer, or it may be eroded and moved before settling again. During this process of erosion, movement and deposition, the sediment may encounter a wide range of physical and electrochemical conditions, causing corresponding changes in its flocculation characteristics and its behaviour. These changes do not end with deposition, as biological, bacterial and chemical action can substantially affect the consolidating sediment.
