Theory 35/Transport & flow/Infiltration
Infiltration Is Rain Against Conductivity
The claim
Whether rain infiltrates or runs off is set by the ratio of rainfall intensity to saturated hydraulic conductivity, so the same storm behaves differently on two soils.
01Mechanism
Ponding begins when delivery exceeds the soil's capacity to transmit.
02Prediction
Runoff should track the ratio.
03Refutation
Runoff tracking total rainfall would remove conductivity.
