Theory 47/Springs/Threshold lens
Springs Stop on a Pumping Ratio
The claim
Spring flow ceases below a threshold in the ratio of recharge to abstraction, so a modest well field can dry a large spring.
01Mechanism
The water table must stay above the spring outlet; pumping lowers it, and the ratio determines whether it drops below.
02Prediction
Cessation should track the ratio.
03Refutation
Cessation tracking abstraction volume would remove recharge.
