✦ Synopsis

In this comment we argue that the premise on which the peat mound model developed by Armstrong (Earth Surface Process and Landforms, 1995,20,473-477) is based, that hydraulic conductivity shows an exponential decline with depth in bog peats, is unsound. Empirical evidence in the literature for such an exponential decline is less sound than Armstrong suggests. In addition, Armstrong's suggestion that the hypothesis of Baird and Gaffney (Earth Surface Processes and Landforms, 1995,20,561-566) supports an exponential decline is shown to be erroneous.
