Roman and Medieval Sea and River Flood Defences

Introductions to Heritage Assets

An introduction to Roman and medieval sea and river flood defences (largely consisting of banks rather than walls).

The banks are normally simple dumps of earth but occasionally have a masonry component. Particularly when connected with land-claim, they are frequently accompanied by a ‘back ditch’ on their landward side, by outfall works to enable water to continue to drain through and off the defended area, and, in the case of seabanks, by breakwaters to protect against storm damage.

Descriptions of the asset type as well as its associations and a brief chronology are included.
