摘要：	In July 2001 a series of severe storms withextreme rain and winds resulted in heavy flooding in West Virginia. The flooding caused damage to several roads and bridges in six counties. A significant landslide developed along a 600-foot section of Cunard River Access Road on the New River Gorge National River creating an 85 feet high sheer face. Flood water reshaped a 27-foot high waterfall located at the base of the slide and formed a large scour pool. Removal of material at the slope face and water flowing through the slope contributed to the slide movement. The subsurface field investigations to obtain soil and rock strength properties for the design progressed in several phases because of the difficulty accessing the unstable edge and toe of the slope. A proposed slide repair design was completed quickly and met environmental and aesthetic constraints and requirements for maintaining of public access during construction and maintaining the original alignment.
