Abstract
We seek to conduct a hillslope safety analysis of a hill located in Roane County, Tennessee, composed of the Gilpin-Petros soils. This unit is composed primarily of residuum from sandstone, siltstone, and shale. The stability of the hill was assessed using a one-dimensional infinite slope-stability model. This model was used to calculate the factor of safety under both dry and wet conditions based on a set of assumptions derived from soil lithology and hydrologic parameters. Simulations in ArcGIS show that under dry conditions, the slope is unconditionally stable at all locations. Under conditions of sufficiently heavy rainfall (>9 inches of rainfall in a 24 hour period), results indicate that the slope becomes unstable at the top and could result in slope failure.
