Description :
A physics-based Integrated Hydrology Model (InHM) was employed to conduct both three- and two-dimensional (3D and 2D) hydrologic-response simulations for the small upland catchment known as C3, located within the H.J. Andrews Experimental Forest in Oregon. Comparison of the 3D results with the 2D results clearly illustrates the importance of convergent subsurface flow. A simple infinite-slope model, driven by sub-surface pore-water pressures generated from the 3D and 2D hydrologic-response simulations, was employed to estimate slope stability along the long-profile of the C3 hollow axis, and to study the impact of forest roads on near-surface hydrologic response and slope stability at the catchment scale.
