Sub-tidal sandbanks

Sub-tidal sandbanks are permanently covered by seawater, typically at depths less than 20m. The sub-tidal environment of the Humber Estuary is highly dynamic and varies according to the composition of the bottom sediments, salinity, sediment load and turbidity, dissolved oxygen and anthropogenic factors relating to water quality and dredging.  The sub-tidal area of the Humber accounts for 55% of total estuary area.
