relatively resistant rocks on one or both sides of a flood plain produce
natural leeves
are somewhat elevated areas of land on either side of a channel
when water leaves their banks

friction on the banks slows
overflowing water and forces the heaviest sediments (like sand and course silt)
the leeves are made up of
sands and course silts
back swamps are
low lying portions of the flood plain lying between the natural leeve and the edge of the flood plain
river terrance

Changing climate or tetonic uplift may cause
down cutting bellow the existing flood plain, and enough time passes a new flood plain is created bellow the original one
waterfalls and rapids
are portions of channels with steep gradients
are deposits of alluvium, formed when streams enter standing water
