The start of a river is called the Source
The end of a river is called the Mouth
The long profile of the river consists of three sections; Upper- where gorges and waterfalls form, Middle- where meanders tend to form, Lower- where deltas and floodplains form
There are four processes of erosion and transportation
Deposition is the putting down of material along the river due to a loss of energy
A waterfall is a steep drop in the course of a river. They form when a band of resistant rock lies over softer, less resistant rock
Meanders are bends in a rivers course
A flood plain is the wide, flat area of land on either side of the river in its lower course
Levees are natural embankments of silt along the banks of a river, which are often several metres higher than the flood plain.
A delta is a flat area of sand and silt built into the sea.
When a river enters the sea carrying large volumes of sand, the velocity slows and causes material to be deposited.
Flooding in MEDC’s has a different impact to flooding in LEDC’s
There are short, medium and long term attempts at managing flooding
