Abrasion
the pebbles being transported wear away the bed and banks of the river channel
1 of 15
Alluvium
rock particles (clay, silt, sand and gravel) deposited by a river
2 of 15
Attrition
The particles are knocked about as they are transported, and they gradually become more rounded and reduced in size
3 of 15
Bedload
the material carried by a river by being bounced or rolled along its bed
4 of 15
Confluence
the point at which rivers meet
5 of 15
Delta
a river mouth choked with sediment causing the main channel to split into smaller branching channels or distributaries
6 of 15
Discharge
the amount of water passing a specific point at a given time. This become larger downstream as a result of the joining of many tributaries. It is calculated as: cross-sectional area x velocity, and measured in cubic metres per second (m³/sec).
7 of 15
Drainage Basin
the land that is drained by a river and its tributaries
8 of 15
Erosion
the wearing away of the bed and banks of the river channel by abrasion, hydraulic action, solution and attrition
9 of 15
Estuary
the tidal mouth of a river, with large, flat expanses of mud exposed at low tide
10 of 15
Eutrophication
high nitrate levels combined with phosphates cause excessive plant and algae growth, a deteriorating process that results in loss of oxygen and the biological death of the river
11 of 15
Flood Plain
the wide, flat floor of a river valley. It consists of sediments (alluvium) deposited by the river
12 of 15
Gorge
a steep-sided, narrow rocky valley marking the retreat of a waterfall
13 of 15
Hydraulic Action
The sheer force of the water by itself can erode material from the bed and banks of the river channel
14 of 15
Interlocking Spurs
As the river descends from the highland, it begins to meander between spurs which interlock down the valley

Amy Bold

Thanks for these. Brilliant material for revision!

Mr A Gibson

This is part one of two sets of cards that you could use together. Between them they offer over 30 terms that a competent student may use in their exam answers - specialist vocabulary is important.
