As the name implies, they are subject to flooding. Flood plains tend to leave fertile soils, enriched by silt. To exploit these, without the risk of inundation, embankments were built up along the river banks. The risk of flooding has been heightened by land drainage, including sub-soil drains, upstream of flood plains. This has led to quicker run-off and more extreme variations in river level.
