  mud coastlines
Mud deposition is typically in protected, low energy environments such as estuaries and lagoons that also have an influx of dominantly fine-grained sediments.
The mud banks of Surinam resemble linear sand ridges on the shelf of the eastern United States in shape, oblique orientation to the coastline, and orientation with respect to dominant direction of transport processes.
The middle part of the intertidal flat is covered for about half of the tidal cycle and the nearly equal periods of suspension and bedload transport generate thin, parallel layered beds of alternating sand and mud with a tendency to coarsen in a seaward direction.

 Reopening of clam flats delayed - The Boston Globe
The Merrimack mud flats were once one of the state's most productive clamming areas, the state agency said in a press release Monday.

When the flats do open, only professional diggers will be allowed to harvest, and any time it rains more than a quarter of an inch near the mouth of the river, they will be subject to closure for at least five days, Kennedy said.
