Description :
Here, the AA. explore the issue of equilibrium landscapes through a previously developed model that predicts the spatial variation in thickness of soil as a consequence of the local balance between soil production and erosion. They present 2 independent methods that can be used to define quantitatively the function of soil production for a study site in Northern California. The results suggest that the study site has been subjected to a wave of incision and varying intensities of erosion because of tectonic and climatic oscillations that have a frequency shorter than the morphologic response time of the landscape.
