Comment on “HydrogeoSieveXL: an Excel-based tool to estimate hydraulic conductivity from grain-size analysis”: technical note published in Hydrogeology Journal (2015) 23: 837–844, by J. F. Devlin

Permeability of sandy soils estimated from particle size distribution and field measurements

“…The original paper [20] and [41,42] support the use of 𝑑 ℎ instead of 𝑑 10 , as often reported in the literature; 𝑛 function fitted by [3] Zamarin (ZAM) [3,32] 𝑘 =…”

Wolfgang Beyer: A Groundwater Scientist from Dresden

“…The literature review for this paper revealed that between 2015 and 2019 at least five review articles were published that compare different existing methods. It is worth noting that the Beyer method was listed in several of these papers among the preferred methods (e.g., Lopez et al ; Fuchs et al ; Urumovic and Urumovic ) and was found to produce the best correlation in investigations with highly heterogeneous soil samples (e.g., Odong ).…”

Erratum : HydrogeoSieveXL: un outil développé sous Excel pour estimer la conductivité hydraulique à parrit de l’analyse de la granulométrie

“…In response to a Comment (Urumović and Urumović, 2016) regarding the original article , an error was noticed in Table 1 The very latest version of HydrogeoSieveXL can be found on t h e U n i v e r s i t y o f K a n s a s ( U S A ) w e b s i t e a t https://kuscholarworks.ku.edu/handle/1808/21763, and any further updates will be executed on this website.
