Roddon

A roddon, also written as rodham, roddam or rodden, is the dried raised bed of a watercourse such as a river or tidal-creek, especially in the Fen district of East Anglia in England. Such raised silt and clay-filled beds are ideal for settlement in the less firm peat of The Fens. Many writers have followed the archaeologist Major Gordon Fowler's preference for the word roddon to define such structures though modern researchers suggest the word rodham is the more correct local word.
