Transcript of Water Resources. What is a Watershed ? Area of land that sheds (moves ) water from the highest to...
Groundwater
Water found in the spaces between soil particles and cracks in rocks underground
A natural resource that is used for drinking, industry and growing crops
Examples: aquifers and springs
Porosity and Permeability
How fast water can flow through a material
Depends on the particle size. The larger the particle size the
more permeable the material.
Impermeable Layer
A layer of material which water does not pass; also known as a confining layer
Examples: Clay and shale(natural), concrete (man-made)
Recharge Zone
Layer below the surface that has holes where water can go through to the Aquifer.
Example: Karst Limestone
