In response to a Comment, several highlighted errors in the original article (Toulier et al, 2022) have been assessed and the corrections are presented here.

The double-ended arrow defining the piezometric head (H) was inappropriately drawn in the original Figures 2 and 3a. Accordingly, the length of the double-ended arrow in these figures has been extended to better represent the vertical datum, namely the sea level (z=0).
