3 human impacts of water cycle?

Answer 1

1) Increased demand for water by humans for domestic and industrial use, has affected the height of the water table and the level of ground water. Drought is occuring in areas where there was not previously a problem.
2) Increase in buildings, roads, concrete and paved areas, has reduced the ability of water to seep into the ground. The increased in run-off into areas too small to cope has increased localised flooding.
3) The change in land use over several hundred years from natural forest to agricultural to urban sprawl has had a significant impact on evaporation and transpiration rates

Answer 2

deforestation - reduced transpiration, increased run-off.

global warming: increased sea temperature - increased evaporation; increased freshwater from glacier melt.

increased particulate emmissions - increased nuclotides for rainfall
