What are River Valleys?
•
River plain valleys
have
broad flat valley floors
with sides of varying angles.
•
The valley bottom is formed by a
meandering river
.
How are River Valleys formed?
•
Plain valleys are created by
slow moving rivers
flowing at moderate to
low angle slopes
.
•
A river at this gradient tends to
erode more along the sides of the channel
than along the bottom.
•
Thus, the river slowly
sweeps across the valley floor
, forming a broad river plain.
