How can we Increase Water Supply Flashcards
How much did it cost to build a water transfer scheme from Wales to Birmingham, and what was it called?
The Birmingham resilience project costed £300 million to create a water transfer scheme from Wales to Birmingham.
What are the four strategies to increase water supply?
Four strategies to increase water supply are dams, water diversion, water transfers, and desalination.
What is water diversion?
When a small dam is built to raise a river’s water level, then new channels are then built to redirect some of the river water to a chosen location.
What are water tranfers?
These are large-scale engineering projects that move water from areas of surplus to areas of water deficit.
What is desalination, and what are the two ways of doing it?
Desalination is removing salt from seawater for use of increasing the water supply. The two ways of doing it are filtering the seawater through a fine membrane, and simple distillation.
Dams involve building a large wall across a river, so…
they flood the land behind, forming an artificial lake known as a reservoir, and generate hydroelectricity, taking carbon emissions away from burning fossil fuels.
Producing hydroelectricity is an advantage of a dam because…
it reduces the need for fossil fuels so there are much less carbon dioxide emissions.
Flooding land and creating reservoirs creates problems because…
it destroys natural habitats and forces people to move.
Often water diversion schemes are preferable to traditional dams because…
they do not require building a reservoir.
The fish that was blocked from travelling down the Colorado river by a water diversion scheme was a:
catfish.
Water Transfer schemes involve moving water from…
areas of surplus to deficit.
Water transfer schemes create large amounts of congestion so…
they create air and noise pollution.
Countries like Malta can only choose desalination because…
the small rivers, lakes and aquifers in the country cannot handle the increasing demand of the increasing population.
Brine is a by-product of desalination, it pollutes water systems so…
it poisons and possibly kills fish.
