Are you looking for delta?
http://en.wikipedia.org/wiki/River_delta
I know that a peneplain is a flat area due to erosion, but what is the term for a flat area due to deposition?
I am generally very successful with searching the internet, but I could not find the term I am looking for.
Could you please help? Thank you!

Thank you Ms. Sue but, unfortunately, this is not the term I was searching for. (It is a longer name. I know there is a pediment, but that, too, is due to erosion, if I remember correctly.)
Delta was a good guess. I also thought of reef. It may be here, along with someother interesting term s; A few other terms:
floodplain -- n. The flat area on either side of an active river channel that can be covered in water when the river is in flood. When the channel is breached, sediment-laden waters spread across the floodplain. When the waters recede, a layer of sediment is left behind. When the floodplain is not covered with water, it commonly supports vegetation and soil formation.
loess -- n. A widespread, loose deposit consisting mainly of silt; most loess deposits formed during the Pleistocene as an accumulation of wind-blown dust carried from deserts, alluvial plains, or glacial deposits.
marine terrace -- n. A platform of marine deposits (typically sand, silt, gravel) sloping gently seaward. Such a platform may be exposed along the coast, forming cliffs, due to uplift and/or the lowering of sea level, e.g., marine terraces of coastal Southern California.
moraine -- n. A mound or ridge of sediment deposited by a glacier; lateral moraine- n. deposited to the side of a glacier; terminal moraine- n. deposited to the front of a glacier; ground moraine- n. deposited on the land surface.
red bed -- n. Sedimentary layers composed primarily of sandstone, siltstone, and shale, that are predominantly red in color due to the presence of iron oxides; often used in reference to the Permian or Triassic sediments of the western U.S.

If not "floodplain," here is one more site to check:
