Evaluating Slope Stability Prior to Road Construction (Classic Reprint)

Excerpt from Evaluating Slope Stability Prior to Road Construction<br/><br/>The hazard potential for mass erosion in the batholith is greatly increased following a disturbance such as logging or road construction. Vegetation removal often results in removal of a critical margin of safety afforded the soil by roots and soil arching between stems (gray and Megahan, Changes in slope hydrology associated with interception and redistribution of subsurface ?ow following road construction also increase the potential for mass erosion (gray and Megahan Jensen and Cole (1965) reported that 80 of 89 landslides occurring in the South Fork of the Salmon River in April, 1965 were associated with roads.
