Theory 15/Phase & ice/Frost heave
Heave Is Freezing Against Supply
The claim
Frost heave magnitude is set by the ratio of freezing rate to water supply rate, so slow freezing with ample water lifts more than fast freezing.
01Mechanism
Ice lenses grow when water migrates to the freezing front faster than the front advances.
02Prediction
Heave should track the ratio.
03Refutation
Heave tracking frost depth would remove water supply.
