Comment on “Numerical study on pore clogging mechanism in pervious pavements”

Abstract In this paper, we draw attention to some inappropriate descriptions and mathematical errors in the recently published article “Numerical study on pore clogging mechanism in pervious pavements” ( Zhang et al., 2018 ), which has employed the computational fluid dynamics – discrete element method (CFD-DEM) coupled model to numerically reveal the pore clogging mechanism in pervious pavements. The inappropriate descriptions about the referred papers ( Luo et al., 2015 , Blais et al., 2016 , Li and Li, 2018 ) which may cause misreading are clarified and communications concerning the errors in mathematical equations are also served in this comment.
