Groundwater Over-Extraction Model
Which of the following is an example of groundwater over-extraction, a process modeled by the differential equation , where the extraction rate (k) exceeds the natural recharge rate ®?
A
A region where groundwater extraction is balanced by equal natural recharge or artificial replenishment.
B
A region where groundwater withdrawal consistently surpasses the natural recharge rate, causing a steady decline in water levels.
C
A region that employs controlled irrigation methods to ensure that extraction never exceeds recharge.
D
An area with minimal irrigation demands, maintaining sustainable water table levels.
