I think you mean a plateau. Plateau: expanse of raised land with a level surface. Also known as tableland, do to the flat tops.
It would be the flood plain or meander belt.
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.
Well it could be a plateau or a mesa depending if it was wide or broud.If it was wide it would probably be a Mesa.If it was broud it would probably be a plateau.
