This article was originally published with incorrectly labeled columns for soil hydraulic parameters in Table 2. The table has been corrected as shown here. In addition, labeling (a, b, and c) has been added to Figure 1 since publication.

  • Note. θi, θs, and θr are initial, saturated, and residual water contents, respectively; α, n, and m are parameters of van Genuchten's (1980) model; Ks is saturated hydraulic conductivity, S is soil sorptivity, and β is an infiltration constant defined by Haverkamp et al. (1994).

The (a) simulated infiltration curve for known values of soil sorptivity (S) and saturated hydraulic conductivity (Ks), (b) temporal variations of the contributions (W) of different terms of the five‐term equation to the infiltration process, and (c) temporal variations of the first term contribution vs. the contribution of remaining terms. The β is an integral infiltration constant, t is time, I is cumulative infiltration data, W is the contribution of the sorptivity and gravity components to the infiltration process, and c(1) to c(5) are constants used in approximate expansions of the Haverkamp et al. (1994) formulation
