Thus it has variable salinity and electrical conductivity over the tidal cycle, and flushes salts from inland soils.
Tidal creeks are characterized by slow water velocity resulting in buildup of fine, organic sediment in wetlands.
Creeks may often be a dry to muddy channel with little or no flow at low tide, but with significant depth of water at high tide.
Due to the temporal variability of water quality parameters within the tidally influenced zone, there are unique biota associated with tidal creeks which are often specialised to such zones.
Nutrients and organic matter are delivered downstream to habitats normally lacking these, while the creeks also provide access to inland habitat for salt-water organisms.

as well as some parts of the United States （near the Chesapeake Bay, parts of New England, and southern Florida）, a creek is a tidal water channel.
In the tidal section of the River Thames in London, the names of the rivers that flow into it all become Creeks for the lower section that is tidal; thus, for example the River Lea becomes Bow Creek in its tidal section.
In parts of southwest England and Wales, the term 'pill' is used, and is found in placenames such as Huntspill.
A narrow channel between islands in the Florida Keys is known there as a creek.
On the India and Pakistan borders the term also applies to the salt water inlets enclosed by mangroves.
Creeks are found dispersed all along the Indian coast.
