Hydrodynamic Porosity: A Paradigm Shift in Flow and Contaminant Transport Through Porous Media, Part II
Abstract. In this work, we build upon our previous finding that hydrodynamic porosity, θmobile, is an exponential function of pore-scale flow velocity (or interstitial Reynolds number). We previously discovered this relationship for media with a square cavity geometry – a highly idealized case of the dead-ended pore spaces in a porous medium. Thus, we demonstrate the applicability of this relationship to media with other cavity geometries. We do so by applying our previous analysis to rectangular and non-rectangular cavity geometries (i.e., circular, and triangular). We also study periodic flow geometries to determine the effect of upstream cavities on those downstream. We show that not only does our exponential relationship hold for media with a variety of cavity geometries, but it does so almost perfectly with a coefficient of determination (R²) of approximately 1 for each new set of simulation data. Given this high fit quality, it is evident that the exponential relationship we previously discovered is applicable to most, if not all, unwashed media.

This review is identical to that of hess-2023-208
The papers contain some interesting results, but also confusing and irrelevant disgressions. See detailed comments in the attached document,

The paper is very well written and is an extension of the first one. The extension of the previous one concerns different type of cavities (triangle, circular, periodic squares). Again, the pore geometry is oversimplified and the results cannot be extended to realistic porous network.
As for the first paper, the main missing elements are the 3D geometry of the pores, the change in the pore diameter and the effects of interconnections.
Both papers are technically very sound but they could be partly improved by studying the relationship between the fitted parameters and the characteristics of the geometry for example.
Therefore, these results are of limited interest for a publication in HESS, which promotes research in Earth Systems. However, I leave the final decision to the editor concerning the suitability of both papers for HESS. If yes, I recommend major revision by merging both papers in one manuscript.
