A summary of the shape and gradient of a river bed from source to mouth.
V-shaped sections, changing downstream for steep to gentle.
The end of a river that flows into the sea, river or lake.
Flat land built of silt on the sides of a river, usually in its lower course.
Semi-circular lake on the flood plain of a river, a cut-off meander.
The mouth of large rivers when there is a lot of sediment or debris that the sea can get rid of quickly.
Raised bank along the sides of a river, made of silt from river floods.
A curve of a river from erosion and deposition.
Fast-flowing turbulent part of a river.
Base of a waterfall, where the waterfall lands.
Eroding against the banks of a river.
Eroding towards the river bed.
Protruding sides of a valley where a river weaves.
When water vapour changes to liquid (warming).
When water vapour changes to liquid (cooling).
Water in any form that falls to earth e.g. rain.
Rain water just runs along the ground, mostly when soil is hard or wet.
The water that is stored within the ground.
Water flows sideways through the soil
Water that is stored e.g. ground, clouds, air.
When the ground water moves through the rock layers.
Rain soaks into the soil/ground.
Rock will not let water through.
Rock that lets water seep through.
Where a river begins.
A small river or stream that joins a larger river.
The area of high land forming the edge of a river basin.
The point at which two rivers meet.
This is where the river flows.
Water and debris is forced into cracks.
Rocks and stones erode the bed and sides of river bank.
Rocks get smaller by chemical action. Rocks such as chalk and limestone.
Rocks get smaller when knocked together.
A narrow, steep-sided valley.
Large boulders roll along the river bed.
Smaller pebbles are bounced along the river bed, picked up and then dropped as the flow of the river changes.
The finer sand and silt-sized particles are carried along in the flow, giving the river a brown appearance.
Minerals, such as limestone and chalk, are dissolved in the water and carried along in the flow, it often cannot be seen.
The time period when the most rain fell
The maximum discharge in the river
Falling flood water in the river
Normal discharge of the river
The rising of flood water in the river
Time difference between the peak discharge and the peak rainfall
Used to show how the water flow in a drainage basin responds to a period of rain
The amount of water that is flowing through a river at one point - measured in cumecs
How fast something is going
The materials carried by a river by being bounced along its bed.
The process where the river no longer has the energy to carry its load
Here, the river has high volume and large discharge
A deposit of clay, silt and sand left by flowing floodwater in river valley
Created on the outside of meander by erosion from fast-flowing water
Created on the inside of a meander from slow-flowing water
The movement of rock or other materials in a river.
The section of the river between the mountains and the lowland
The wearing away of the bed and banks of the river channel by abrasion, hydraulic action, solution and attrition
The mountain stage of a river with steep gradients and lots of erosion
Form where the river meets a band of softer rock after flowing over an area of more resistant material. They progressively cut back, leaving a gorge
They are usually found in the upper course of the river where the water has considerable erosive power
The pebbles being transported wear away the bed and banks of the river channel
