Interactive comment on “A model of landslide triggering by transient pressure waves
Abstract
Hydraulic diffusivity coefficient in Iverson’s (2000) paper and Pressure head diffusivity
coefficient in our manuscript may appear as a matter of semantics, but they do not
describe the same physical process, as indicated by referee 2. The former describes
the transmission of water through soil, while the latter describes the transmission of
pressure head through pore water (or even pure water, not in a poroud media) . This is
also reflected in the respective boundary conditions for which the models are solved.
While our model is solved for pressure head condition from the kinetic energy of an
intense rainfall at the ground surface (Waswa and Lorentz, 2014: page 2368, Eq. 11),
Iverson’s model is solved for pressure head condition from infiltration of rainwater at
the ground surface (Iverson, 2000: page 1901, Eq. 25c).
