摘要:Pikes Peak Highway is a partially paved road between Cascade, CO and the summit of Pikes Peak (4300 meters).Significant gully erosion is occurring on the hillslopes due to the concentration of surface runoff along the road surface andadjacent drainage ditches. As a result, large quantities of sediment are transported to the surrounding valley stream networkscausing significant damage to riparian, wetland, and aquatic environments. This study addresses the rates of gully erosionalong the Pikes Peak Highway.
