Sensitivity Analysis and Validation for Numerical Simulation of Water Infiltration into Unsaturated Soil

Table 1

The coefficient values from Haverkamp et al. (1977) [7] based on (10). These values were used as base case. Note that is residual volumetric water content, is saturated volumetric water content, is saturated hydraulic conductivity, and , , , and are fitting coefficients.
