Short summary
The channel flow model proposed by Marques et al (2018) for the Himalayas has a geometry that would not generate any excess pressure. The excess pressure calculated by the authors, based on a different and highly improbable geometry, is so high that the overlying rocks would not be able to contain it: they would bend or break in such a way as to relieve the pressure. The conclusions drawn by the authors are therefore unwarranted and misleading.
