"Webbthis means in soils is that any change in the discharge with depth has to be balanced with a change in the soil moisture. Like this: =0 ∂ ∂ + ∂ ∂ z q t θ where θ is the moisture content of the soil. This is a simple statement of continuity, just like we had before. If water goes in (through discharge), it increases the soil moisture. " - Richards soil
