Most flood embankments are between 1 metre and 3 metres high. A 5-metre-high (16 ft) flood embankment is rare.

A flood embankment of 2.5 metres high requires an outreach of 15 metres, which makes it unsuitable in some areas.

To prevent seepage through the embankment a central core is added to acquire stability and integrity.

When the structure has moved sideways exposing the foundation to erosion
