The phrase "a bed of sediments" is correct and usable in written English.
It can be used in contexts related to geology, environmental science, or discussions about sedimentary layers in various settings, such as rivers, lakes, or oceans.
Example: "The researchers discovered a bed of sediments that revealed important information about the region's geological history."
Alternatives: "a layer of sediments" or "a deposit of sediments".
Larval lampreys were collected from the river Ulla (Galicia, Spain), with permission from the Xunta de Galicia, or provided by Lamprey Services, Inc. (Ludington, MI, USA) and maintained in aerated fresh water aquaria at 15 23 °C with a bed of river sediment until their use in experimental procedures.
Other rocks, like the mudstone shown here, display the flat bedding of sediments deposited at the bottom of a lakebed.
Discontinuous beds of sediment were deposited in broad channels eroded into the Moenkopi, creating the locally 0 to 90 foot (0 to 27 m) thick white to yellowish gray cliff-forming Shinarump Member of the Chinle Formation.
A large weir height leads to huge sedimentation volumes and thus to a lack of sediments and to river bed erosion downstream of the hydropower plant.
The idea, he added, has been verified as geologists have roamed the globe over the decades and repeatedly found that beds of marine sediments are "a good predictor" of where to discover oil.
Sewer design based on consideration of flow with non-deposition with a bed deposit reduces channel bed slope and construction cost in which the presence of a small depth of sediment deposition on the bed increases the sediment transport capacity of the flow.
The Lower Birimian is principally pelitic in origin having muds and silts with beds of coarser sediments (Kesse 1985).
Evidence for this is in cross-bedding of the sediments and large numbers of fish fossils.
Micritic-limestone beds were deposited during a period of sediment starvation coeval with the maximum marine inundation in the basin (MFZ).
There remains a need to address environmental concerns about the potential impacts of TSTs including the suspension and deposition of bed sediments if TSTs are to be more widely accepted and deployed.
