MEANDERMost erosion normally occurs on the outside bend of a meander. This is because the velocity (speed) of the river is faster. As well as the water hitting the banks, pieces of sediment may also be thrown
against the river banks wearing them away.
On the inside bend of a meander, the
water flows more slo
wly. There is
normally deposition on the inside
bend. This is because the sediment is
too heavy for the riv
er to carry.
RIVERSRivers start as very small streams
and gradually get bigger as more and
more water is added. Heavy rains
and spring meltwater add so much
water to some rivers that they
overflow their banks and flood the
surrounding landscape.
When a river reaches a
lake or the sea the water
slows down and loses the
power to carry sediment
Larry. The sediment is
dropped at the mouth of
the river. Some rivers
drop so much sediment
that waves and tides can't
carry it all away. It builds
up in layers forming a
delta.
TributaryA tributary or affluent
is a stream or river
that flows into a main
stem (or parent) river
or a lake. A tributary
does not flow directly
into a sea or ocean.
Tributaries and the
main stem river serve
to drain the
surrounding drainage
basin of its surface
water and
groundwater by
leading the water out
into an ocean or sea.
Confluence a confluence is the meeting of two or
more bodies of water. Also known as
a conflux,[1] it refers either to the
point where a tributary joins a larger
river, called the main stem, or where
two streams meet to become the
source of a river of a new name, such
as the confluence of the
Monongahela and Allegheny rivers in
Pittsburgh, Pennsylvania creating the
Ohio River.
