drainage basin
the area of land drained by a river and its tributaries
1 of 33
a stream or small river that joins to a larger one
2 of 33
solid creep
where individual particles of soil move slowly down a slope
3 of 33
where masses of soil or rock, usually mixed with water, flow like liquid downhill
4 of 33
the volume of water flowing in a river, measured in cubic metres per second {cumecs}
5 of 33
where materials move rapidly down slope in one go, like a landslide
6 of 33
the starting point of a stream or river, often a spring or lake
7 of 33
interlocking spurs
an area of higher land jutting out of a steep valley sides in a rivers upper course
8 of 33
plunge pool
a hollow under a waterfall created by erosion and filled by water
9 of 33
a steep, narrow valley with rocky sides
10 of 33
vertical erosion
downward erosion like a river bed
11 of 33
a bend formed in a river.
12 of 33
lateral erosion
erosion where a river cuts sideways into its banks
13 of 33
river cliff
a steep section of river bank, caused by fast-flowing water eroding the outside of a meander
14 of 33
slip off slope
the gentle slope on the inside of a meander bend formed by deposition
15 of 33
point bar
sediment laid down on the inside of a meander bend where the river flows slowly
16 of 33
a diagram showing the shape of a feature or landscape as if it was cut through sideways
17 of 33
the narrow ***** of land between the two closest banks of a meander
18 of 33
flood plains
the flat land in a valley floor each side if the river channel, which is sometimes flooded
19 of 33

22 of 33
a large lake, usually artificial, used to store water
23 of 33
the deepening and/or straightening of a river to allow it to carry more water
24 of 33
the process where by water soaks into the soil and permeable rock
25 of 33
jet stream
a fast-moving current of air in the upper atmosphere
26 of 33
hard engineering
strategies using artificial structures to prevent river or coastal flooding
27 of 33
soft engineering
flood defences that work with natural processes to reduce the risk and impact of coastal or river flooding
28 of 33
a graph showing changes in a rivers discharge and rainfall over time
29 of 33
rising limb
represents the rapid rise in water after a period of heavy rainfall
30 of 33
lag time
the difference between the time of the heaviest rainfall and the point at which the river contains the largest amount of water
31 of 33
falling limb
shows the reduction in the amount of rainfall reaching the channel
32 of 33
a process where sediments are dropped by the river, glacier or waves that carried them
