RIVERS

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.
