alluvion

Alluvion, al-lū′vi-un, n. land gained from the sea by the washing up of sand and earth.

The whole party crowded to the spot where Uncas pointed out the impression of a moccasin in the moist alluvion.

Further down, abrupt cliffs and overhanging precipices are frequently seen at the termination of the river alluvion.

The cypress begins near the mouth of the Ohio and spreads through the alluvion portions of the Lower Valley.

Immediately on the banks of the Ohio and other large rivers are strips of rich alluvion soil.
