Erosional landforms
Features often found in the upper course of the river.
1 of 17
Waterfall
A waterfall is a sudden drop along the river course.
2 of 17
Gorge
A steep-sided valley is left where the waterfall once was.
3 of 17
Interlocking spurs
Hill that a river meanders around in a V-shaped valley. When viewed from downstream, these spurs appear to be locked together.
4 of 17
Erosional and depositional landforms
Features often found in the middle course of the river.
5 of 17
Meanders
A bend in a river
6 of 17
Oxbow lakes
a curved lake formed from a horseshoe bend in a river where the main stream has cut across the narrow end and no longer flows around the loop of the bend.
7 of 17
Depositional landforms
Features often found in the lower course of the river.
8 of 17
Floodplain
an area of land which is covered in water when a river bursts its banks.
9 of 17
Levees
Ridges or banks formed by deposits of alluvium left behind by the periodic flooding of rivers. Can also be artificially constructed banks or walls.
10 of 17
Estuary
where the river meets the sea.
11 of 17
Alluvium
The sediment deposited by rivers. Also known as silt.
12 of 17
Discharge
The volume of water in a river passing a point in a given time. Measured in cumecs (cubic metres per second).
13 of 17
Mudflat
Sheltered coastal areas where mud is deposited by tides or rivers.
14 of 17
Plunge pool
The pool of water found at the bottom of a waterfall. It is an erosional feature which has been created by a combination of hydraulic action and the abrasion of the plunging water.
15 of 17
River cliff
Steep bank created on the outside of a river bend by the erosive effect of fast-flowing water undercutting the bank.
16 of 17
Slip-off slope
Gently sloping bank found on the inside of a river bend because of slow-flowing water, depositing sediment.
