Where a River starts
its journey
Springs. Some rivers begin
where water flows out of
rocks.
Rainwater sinks through the
soil and trickles through the
cracks and spaces in rocks
such as chalk and limestone.
Lakes.
Melting snow and ice.
Bogs.
Dishcharge
The amount of water flowing in a river
per second.
Meander
A meander is a bend in a
river. Meanders normally
occur in the middle and
lower courses where the
water is moving more slowly.
The river carves out Sshaped bends.
Banks
are the sides of a river
or stream between which
the water normally flows
Rivers have two banks - the
right bank and the left bank.
If you stand in a river and
face the way the water is
flowing, the right bank will be
on your right hand side and
the left bank will be on you
left hand side.

Bed
The river bed is the
bottom of the river.
It can be made of
stones, pebbles,
boulders, rock and
mud
Braiding
A braided river course is where the river
channel splits into several channels.
Small islands of sand, mud and silt are
deposited between these channels.
Sometimes trees and plants can grow on
this deposited sediment
Deposition
A river lays down or drops the
sediment or material that it is
carrying such as sand, mud, and
small stones or sticks. This often
happens on the inside of meanders,
because the water is flowing
slowly.
Sediment
The name given to material that has been
carried by rivers or the sea and then
deposited. Sediment may be called
alluvium if it deposited on the bed or a
river, it may be called a beach when
deposited by waves.
Delta
A fan-shaped area of sediment built up at
the mouth of a river
