Discussion of 'Effects of Aggregate Masking on Soil Infiltration under an Aggregate Bed' by William D. Martin Ⅲ, Nigel B. Kaye, and Bradley J. Putman

摘要

The discussers would like to thank the authors for their research in investigating the effect of masking and embedding on decreasing hydraulic conductivity. The discussers, however, would like add a few points about this research. 1. The results of Fig. 7 in the original paper show that the reduction of hydrualic conductivity (K) resulting from masking and embedding conditions is in the range of 9-53% for masking and in the range of 27-66% for embedding. This is a wider range than presented by Radcliffe et al. (2005) in Table 1 in the original paper. This result is caused by a wider range of ratio K (open: restricted) in the original study.
