Terminology is identical in both dialects. However, related terms like 'levee' (more common in US, especially for earthworks) or 'embankment' (common in UK) are near-synonyms with slightly different technical specifications.
Connotations
Neutral technical term in both. In the UK context, may be associated with government Environment Agency projects. In the US, may be discussed in contexts like New Orleans' flood defense system.
Frequency
Comparable frequency in technical contexts. Slightly higher public discourse frequency in US due to major flood events (Hurricane Katrina).
