Riparian came to English from the same source that gave us riverthe Latin riparius, a noun deriving from ripa, meaning "bank" or "shore." First appearing in English in the 19th century, riparian refers to things that exist alongside a river (such as riparian wetlands, habitats, trees, etc.). Some river communities have laws called "riparian rights," referring to the rights of those owning land along a river to have access to the waterway. Note the distinction of this word from littoral, which usually refers to things that occur along the shore of a sea or ocean.
