Store
Places within a system where materials or energy are held for a time
1 of 20
Transfer
Flows of water between stores in the hydrological cycle
2 of 20
Precipitation
The deposition of moisture on the Earth's surface, in the form of dew, frost, rain, hail, sleet and snow
3 of 20
Watershed
The dividing line between two drainage basins
4 of 20
Channel network
The system of tributary streams that join an increasingly large river channel in a drainage basin
5 of 20
River regime
The seasonal pattern of river discharge over the course of a year in response to precipitation, temperature, evapotranspiration, drainage basin characteristics
6 of 20
Discharge
The quantity of water that passes a given point on a river bank within a set period of time
7 of 20
Hydrograph
A graph showing a river's rate of discharge over time as it goes past a specific point
8 of 20
Peak discharge
The point at which the river channel reaches its highest level of discharge after precipitation occurs
9 of 20
Lag time
The difference in time between peak rainfall and peak discharge. Affected by permeability of rock, amount of vegetation, amount of rain, channel density (number of tributaries), relief
10 of 20
Surface run-off
When water flows over the surface of the ground
11 of 20
Erosion
The wearing away of land by water, ice, wind and gravity
12 of 20
Weathering
The chemical alteration and physical breakdown of rock in its original position
13 of 20
Mass movement
The movement of weathered material down a slope without the direct action of running water
14 of 20
Meander
A pronounced bend in a river
15 of 20
Water quality
A measure of how fit water is for human consumption. Polluted water has low water quality
16 of 20
Deposition
When sediment is dropped from the river. Ocurrs when there is a decrease in the energy, speed and discharge of the river
17 of 20
Floodplain
An area of low land in the middle and lower course of the river that is susceptible to flooding when precipitation levels are high
18 of 20
Soft engineering
Methods to avoid flood damage i.e afforestation, preserving marshes, zonation of urban areas
19 of 20
Hard engineering
The building of structures such as dams, embankments (levees), flood relief channels, sluice gates to hold back/ divert floodwater
