What factors might effect the supply for water across uk 6 points
Water leaks from pipelines , dam being created, climate and precipitation, over - abstraction , geology, pollution of water
List 3 positives of a water transfer scheme
- jobs will be created, building and maintaining the infrastructure
- recreational opportunities as result of the construction of dams and reservoirs
- reservoirs offer new hapbbitats for plants and animals
Name 3 disadvantages of a water transfer scheme
- very expensive to build and maintain
- the river flow downstream could be affected with flooding
- dams can disrupt fish migration and breeding
What is eutrophication name the 6 steps
1) nutrients (from fertiliser ) added to the water
2) algae then bloom ( grow rapidly)
3) algae rises to the surface and blocks sunlight
4) plant life dies
5) bacteria feeds on dead plants , multiply
6) oxygen used up by bacteria, causing animals (fish) to die

Define Johed
Small earth and sand dams: capture and store rainwate, aiding in replie shingle ground water levels
Define pats
These are irrigation channels that distribute water to fields. System operates on a rotational basis where villagers take turns maintaining and using it.
Define water table
The boundary between water- saturated ground and unsaturated ground. Bellow water table are pockets of water called aquifers
Define water logging
Over Saturation of the soil with water due to over irrigation or poor drainage
Over abstraction
Excessive extraction of water from a natural resource beyond its sustainability capability
Define Unregulated pumps
Pumps used to extract ground water or surface water without proper regulation or oversight.
