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).
