L5 Flashcards
What are the three main hydrological processes?
Evaporation
Condensation
Percolation
What is small scale water management?
An intermediate technology solution to any water related problem, this usually costs a significantly smaller amount than a large scale management project.
What is large scale water management?
A solution to water related dilemmas via the use of advanced technology, this usually costs a large amount of money and takes a long time to develop.
What is precipitation?
Rain, Snow or sleet that falls to or condenses on the ground.
What is overland flow?
Overland flow is the movement of water over the land, down slope toward a surface water body. Overland flow is a very important aspect of the water cycle and can be generated under two different physical mechanisms.
What is through flow?
the flowing of liquid or air through something.
What is groundwater flow?
In hydro geology, groundwater flow is defined as the “…part of stream flow that has infiltrated the ground, and has been discharged into a stream channel, via springs or seepage water”. It is governed by the groundwater flow equation.
What positive functions does the Abingdon reservoir have?
Stores water and could generate HEP
Can design for local e.g. windsurfing
What negative functions does the Abingdon reservoir have?
Potential loss of farmland
More likely to flood
Disease and mosquitoes ( especially in poorer countries)
Methane accumulates as a result of rotting vegetation.
Where is the river Thames located?
Southern England, London
Where is the Queen Mary reservoir located?
borough of Spelthorne in Surrey
Can river pollution be regulated?
Yes it can, here are some solutions: Narrowing of a river More efficient removal of increasing rubbish Built riverside roads and walkways Covered huge pipes carrying sewage.
What is the Water cycle?
the cycle of processes by which water circulates between the earth’s oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.
What are the outcomes of an unreliable water supply?
Disease
poor sanitation
unclean drinking water
political problems
Causes of river pollution?
Nuclear plants
fertilizers
litter
