silts
Fine delta particles
Silt is fine sediment—finer than sand but coarser than clay—deposited by water.
Rivers carry silt downstream, leaving fertile deposits on floodplains.
As a verb, to silt or silt up means to become clogged with sediment: The harbor silted up over decades of neglect.
Silts is the plural noun or third-person verb form.
