Dependency of soil moisture distributions and gravity changes on saturated permeability, Ks. For Ks equal to (1) 2.0 × 10−8, (2) 3.0 × 10−8, (3) 5.0 × 10−8 (default value: thick line), (4) 7.0 × 10−8, (5) 1.0 × 10−7 [m/s]. (a) Steady-state soil moisture profile with p = 1.0, θs(Z; p = 1). (b) Time variation of soil moisture at 50 cm below the ground surface with p = 1.0, θ(zs − 0.5, t; p = 1). (c) Gravity changes due to soil moisture distribution, gw(t).
