Discharge An outflow of water from a stream, pipe, aquifer, or watershed.
Drawdown A lowering of the groundwater level caused by pumping
Flow Rate The time required for a volume of groundwater to move between points

Infiltration rate The quantity of water that enters the soil surface in a specified time interval
volume of water per unit of soil surface area per unit of time How infiltration rate is often expressed
Monitoring well A non-pumping well that is used to measure the elevation of a water table or water quality
Overwithdrawal Withdrawal of groundwater over a period of time that exceeds the recharge rate of the supply aquifer
Overdraft, Mining the Aquifer Mainly known as overwithdrawal
