The process is not strictly contingent upon tidal ebb and flow : circadian dews and rainfalls can produce identical cycling.
Over the last few years there has been a tidal wave of literature on the subject.
The estimated speed of the steady flow is greater than that expected for maximum flood-generated flow of tidal periodic flow.
The total cycling volume is comparable to the tidal pool scenario.
The main plants include a variety of microalgae (diatoms), green and red algae and, usually at lower tidal levels, various seagrasses.
The up-estuary, tidally averaged salinity increases with increasing tidal range and decreasing run-off.
In terms of occupied space, they may literally monopolise the upper sediment strata at lower tidal levels (personal observation).
Careful allowance is made for the flooding and uncovering of tidal flats; formulae are proposed for bottom friction in extremely shallow waters.
