Water Management and Environmental Impact

These flashcards summarize key concepts related to water management and its environmental impact, focusing on peat bogs, groundwater, and the effects of water abstraction.

What effect does digging drainage ditches have on water flow?

It increases the speed of water flow.

What is the impact of peat bogs on water retention?

Peat bogs increase water retention capacity.

How does heavy abstraction of water affect groundwater resources?

It reduces the long-term groundwater resource available.

What happens to rivers, lakes, and wetlands when groundwater is no longer feeding them?

They can dry up.

What is the result of reduced evaporation and transpiration due to changes in groundwater?

It decreases water availability and stresses vegetation.

What is the North-Western Sahara Aquifer System known for?

It is one of the world's largest underground reserves of fossil water.

Why is natural recharge of aquifers minimal in the Sahara?

Because rainfall is extremely scarce.

What greenhouse gases are released from exposed peat due to oxidation?

Carbon dioxide and methane.
