A floodplain, or flood plain, is flat or nearly flat land adjacent to a stream or river that experiences occasional or periodic flooding.

The part of a river that is underwater when the river overflows its banks is called the flood plain.
A coastal plain is a streach of land along a seacoast which slopes down. In most cases it is an elevated part of the oceanfloor. A flood plain is the floor of river valley beyond the river bed. It is formed by mud, sand and silt
The flat, wide area along a river is called its flood plain. This is sometimes part of a larger area called the alluvial plain, which formed as the river shifted over time and deposited soil when it flooded.

A delta is formed at the mouth of a river where sediment is deposited, creating a fan-shaped landform. A floodplain, on the other hand, is the flat area around a river that is covered in water during times of flooding. Essentially, a floodplain is an area that can be part of a delta but not all deltas have floodplains.
Tewksbury, Mass. has no major rivers. The Shawsheen and the Merrimack are in other towns. Flood plain is the area that would be underwater if a river flooded. Although the area around Silver Lake and Lubbers Brook in Wilmington, near the southern part of Rt 38 in Tewksbury is pretty flat, it still would not flood, because of the small likelihood that Silver Lake would ever overflow. Areas where rain overflows the streets during storms might be considered to be flood plains in a small sense.

It is down to geographic reasons in terms of the river Suir flowing through the town and tending to flood. Work is ongoing on a flood defence system to help deal with the problem. Clonmel is built on a flood plain, much like the Egyptians built on the nile delta, its because historically the river flooding would have yielded fertile ground, and later a source of trade. The flood defence system will not work in clonmel due to the age of the town, only certain sections of roads can be stopped from flooding, leaving the entire "old bridge" part of the town liable to flood the whole time. Currently only a small section of the flood defence system has been implamented, the rest has yet to materalise.
An embankment could mean a raised bank along a river as part of flood defences.
