Rivers [IGCSE Geo]
Terms in this set (...)
Rocks carried along by the river wear down the river bed and banks (sandpaper motion).
The planting of trees (a method to reduce flooding by increased interception).
A deposit of clay, silt, and sand left by flowing floodwater in a river valley or delta, typically producing fertile soil.
Rocks being carried by the river smash together and break into smaller, smoother and rounder particles.
The point at which 2 rivers meet.
The dropping of sediment that was being carried by a moving force
The volume of water flowing through a river at a certain point.
The area of land drained by a river and its tributaries
The wearing away and removal of material by moving a force such as the flow of a river
The relatively flat area forming the valley floor on either side of a river channel, which is sometimes flooded
The predicted frequency of floods in an area
The rocks or soil which make up the solid part of the earth
Water that flows underground.
Using solid structures to resist forces of erosion
The force of the river against the banks can cause air to be trapped in cracks and crevices. The pressure weakens the banks and gradually wears it away.
A graph which shows the discharge of a river, related to rainfall, over a period of time
Integrated river management
A holistic system of managing rivers that takes an overview of the whole river basin and the relationship between its different parts
Not allowing water to pass through.
When precipitation is interrupted in its fall to the ground e.g. by trees.
When water passes through a permeable surface e.g. soil.
Areas of high land which stick out into steep sided valleys
Natural embankments of sediment along the banks of a river
The gradient of a river, from it source to its mouth
That part of a river system that is close to the mouth of the river
The bend formed in a river as it winds across the landscape
Middle (mid) course
The central section of a rivers course
The point at which the river meets a sea or lake.
An arc-shaped lake which has been cut off from a meandering river
Allows water to pass through it.
Steep outer edge of a meander where erosion is at its maximum
Small pebbles and stones are bounced along the river bed.
Usually sand, mud or pebbles deposited by a river
Inner gentle slope of a meander where deposition takes place
minerals are dissolved in the water and carried along in solution
The highest point of the river - its starting point.
Water from rain, snowmelt or other sources than runs over the land.
fine light material is carried along in the water
Large boulders and rocks are rolled along the river bed at times of high discharge.
A smaller river that joins a larger one.
The source area of a river, often in an upland or mountainous region
The development and growth of towns and cities
Sudden descent of a river or stream over a vertical or very steep slope in its bed
The boundary between drainage basins (normally higher land).
The breakdown of rock by natural processes, without the involvement of any moving forces.
