Abrasion
the wearing down on river bed and banks from the rocks that are carried by the river
1 of 41
Attirtion
Rocks smash against each other and become smaller, smoother and rounder
2 of 41
Hydraulic Action
the sheer force of the water against the river banks erodes them
3 of 41
Solution
the dissolved rock in the water
4 of 41
Interlocking spurs
hills on either side of the river. river flows around them causing them to interlock
5 of 41
Corrosion
 Corrosion is the melting of the bed and banks
6 of 41
Rapids
 Rapids are when there is less and more resistant rock. The less resistant erodes first and causes bumps in the river. The river is insufficient and goes around the more resistant rock causing it to jump
7 of 41
Dam
 Dam barrier in a river to prevent water from flowing/to divert water and to raise water level
8 of 41
Deposition
 Deposition is the dropping of the load by a river. It deposits the larger material first, then the smaller particles- sorting.
9 of 41
Erosion
 Erosion is the wearing down of the river bed and banks and in some cases rock/load
10 of 41
Evaporation
 Evaporation The vapourisation of a liquid- liquid to gas = evaporation
11 of 41
Evapotranspration
 Evapotranspiration is the movement of water from land to the atmosphere  Flood is the overflow of water over the river sides
12 of 41
Flood
 Flood is the overflow of water over the river sides
13 of 41
Floodplain
 Floodplain is the area of land which is subject to flooding- very fertile land
14 of 41
Gorge
 Gorge a narrow valley with steep rocky walls situated between hills and mountains
15 of 41
Groundwater flow
flow is the water stored underground in the soil
16 of 41
Hard Engineering
is an expensive way of managing natural processes
17 of 41
Honepot site
is a tourist hotspot and can be referred to as sacrificial site
18 of 41
Hydrograph
 Hydrograph is a graph that shows the rate of discharge v time
19 of 41
impermable
won’t allow fluids e.g. water to flow through
20 of 41
infiltration
 Infiltration is the process by which water enters the soil
21 of 41
Lateral erosiion
 Lateral erosion is erosion that causes the river channel to widen and deepen
22 of 41
leeve
 Leeve is an embankment to prevent flooding/ mounds on the side of a river
23 of 41
load
 Load is material transported by a river
24 of 41
meander
bends in a river
25 of 41
ox bow lake
is a curved lake formed from a horseshoe bend in the river
26 of 41
peak discharge
 Peak discharge is the highest flow in the channel and the time taken for a river to reach it.
27 of 41
peak rainfall
rainfall is the time of the highest rainfall
28 of 41
percolation
 Percolation is the passing of a liquid through a porous object
29 of 41
precipitation
 Precipitation is any type of water that is in the atmosphere and falls down on to the surface of the earth eg. Rain
30 of 41
river
 River is a large stream of water flowing in a channel
31 of 41
saltation
the transport of hard particles over an uneven surface via bouncing
32 of 41
soft engineering
Ecological and econmonical way to reduce erosion
33 of 41
storm surge
a rising of the sea due to wind and atmospheric pressure changes associated with a storm
34 of 41
Suspension
Transportation proccess which caries sediments (small particles)
35 of 41
Throughflow
The movment of the water within the soil downwards towards the river. Above the water table
36 of 41
Traction
When large boulders roll along the river bed
37 of 41
Transport
The movement of load etc.
38 of 41
Waterfall
River's steepfall into a plunge pool over overhanging rock
39 of 41
Lag time
The time between when rainfall occurs and when it reaches the river
40 of 41
watershed
boundry dividing 2 drainage basins
