sediments
Bottom of rivers
Sediments are particles that settle at the bottom of a liquid.
In geology, sediments are fragments of rock, soil, or organic matter deposited by water, wind, or ice—the raw material that eventually becomes sedimentary rock.
Wine sediments are the grainy residue in aged bottles: Decant carefully to leave the sediments behind.
The verb sediment means to deposit or settle as sediment.
