- An aquifer is an underground water reservoir.
- Some aquifers are depleted by overuse, with a rate of meters per year.
- Dangers of pollution of groundwater.
Understanding groundwater, a project in India
When we have small gardens, we may forget how important groundwater is. This first video tells about confined and unconfined aquifers, groundwater over-exploration and well inventorization, or to inventorize wells in an area.
Second video about a groundwater study in India. As a gardener or farmer we should understand the mechanics of groundwater.
Some topics in this video:
- Drawdown of groundwater when water is pumped.
- Recharge of groundwater through rain.
- Discharges of groundwater by pumping and other mechanisms.
- Mineralization of groundwater.
- Salinization of groundwater and soils.
