Reply to comments by Muñoz-Carpena et al. on “Modeling slope rainfall-infiltration-runoff process with shallow water table during complex rainfall patterns”

Abstract

We appreciate the comments by Muñoz-Carpena et al. (2021), which pointed out some inconsistency between our work and their results. After a thorough examination, we identified an inaccurate description of the soil hydraulic property model applied in Wu et al. (2021) and an associated inconsistency in parameterizing the model in Section 4.1 and Figure 6. After correcting the parameters, we found that the simulated infiltration rates of Wu et al. (2021)’s model, SWINGO, and Hydrus-1D are close under both steady and unsteady rainfalls. Moreover, Wu et al. (2021)’s model has been further validated using the experimental data of Vachaud et al. (1974) and Chu (1997) and the results show satisfactory performance of Wu et al. (2021)’s model in simulating infiltration in soils with a shallow water table (WT).
