Morphology
alluviation = alluviate (opaque) = alluvi + ation
The word is a technical nominalization built on a rare stem and is not readily recoverable from familiar modern English parts by an average learner.
Etymology
Alluviation comes from Latin parts like alluv- (from ad- 'to' + luere 'to wash'), giving the picture of water washing soil and stones into one place. That's why alluviation means the process of sediments, like sand and gravel, being moved and left by water.
