Flood embankment Flood embankment A flood embankment is traditionally an earth wall used to shore up flood waters. Most flood embankments are between 1 metre and 3 metres high. A 5 metre high flood embankment is rare.

Embankment dam to fracture into smaller and smaller sections of earth or rock until these would disintegrates into a thick mud soup of earth, rocks and water. Therefore, safety requirements for the spillway are high, and require it to be capable of containing a maximum flood stage. It is common for its specifications to be written such that it can contain a hundred year flood. Recently a number of embankment dam overtopping protection systems have been developed. These techniques include the concrete overtopping protection systems, timber cribs, sheet-piles, riprap and gabions, reinforced earth, minimum energy loss weirs, embankment overflow stepped spillways and
