Comment on “Modeling slope rainfall-infiltration-runoff process with shallow water table during complex rainfall patterns” by Wu et al. (2021)

Abstract

In this comment we draw attention to parametrization errors in this recently published article when comparing an existing model for soil infiltration under shallow water conditions, SWINGO, with an alternative solution and Richards benchmark solution. After correcting the errors, a new model comparison shows SWINGO ability to match the other approaches and supports the general validity of SWINGO’s simplified approach against the more complicated solutions.
