Transcript of Jskerce Groundwater Discharge

Ground Water Discharge Some of the precipitation that falls onto land infiltrates into the ground to become ground water. Ground water is a vast amount water that is stored underground and is unseen. Once the water that has fallen in the ground, the water travels close to the surface and emerges quickly into stream beds, but because of gravity most of the ground water gets sucked deeper in the soil. Unconfined Aquifers- In unconfined aquifers, water has simply infiltrated from the surface and saturated the subsurface material. If people drill a well into an unconfined aquifer, they have to install a pump to push water to the surface.
Confined Aquifers- Confined aquifers have layers of rock above and below it that are not very permeable to water. Natural pressure in the aquifer can exist; pressure which can sometimes be enough to push water in a well above the land surface. No, not all confined aquifers produce artesian water, but, as this picture of an artesian well in Georgia, USA shows, artesian pressure can force water to the surface with great pressure. People use aquifers to get water for drinking and irrigation. They get the water out by using Artesian well pumps. Under Ground water is generally like a sponge. It takes up the unoccupied space in the rocks and soil particles. If groundwater want to be a big part of the water cycle it can stay still, it alays has to be moving. That depends upon the aquifers and layers of subsurface rocks and also the permeability which means how easy or hard it is to move. BY: JUSTIN SKERCE THE END
