Alluvion

Part of speech: noun

Definitions

1. The natural process where soil and sediments are carried by water to create new land forms occurs alongside the accretion of fresh material over time
2. The gradual accumulation of sediment deposited by water can lead to the formation of new land, resulting in both the alteration of landscapes and the addition of fertile soil
3. The process of sedimentation from flowing water results in the development of new land areas while enhancing the surrounding environment with nutrients

Etymology: Alluvion sounds like a geological term that has always existed, but it is a legal word first. In English law, it names the gradual addition of soil to a riverbank or shore by the slow action of water, and the land gained this way belongs to the owner of the adjacent property. The same idea runs through the geology sense, which covers the deposits rivers leave behind as they build up floodplains and deltas. The word comes from Latin "alluvio," a noun built from "alluere," meaning "to wash against" or "to flow against," combining "ad-" ("to") with "luere," "to wash." The Latin root is the same one behind "lave" and "lotion," so the word's core image is simply water washing material up against land.

Synonyms: flood
