Groundwater July 9th Lecture 18
Fresh Water Availability:
Aquifer: unit of rock from which water can flow and fill into pore-space
-ground water is what's inside an aquifer
Water table: depth at which you will encounter water
Capillary Water: an area through which water can move through capillary action
Storage and Movement:
Porosity:how much space in between stuff
flow cannot happen fast enough=cone shape
big well and pump a lot= suck up salt water and contaminate drinking supply
-rising sea levels=more pressure--> can create contamination?
suck out water from the ground and reduce pressure of pore-space
-water going through the ground--> limestone will react w/ acidic groundwater and form
Sinkholes: anytime you have a removal in the ground due to flowing water?
suck out enough groundwater quickly enough, you will destabilize it
water table to stabilize?
