Proceedings of the 2014 Rocky Mountain Geo-Conference held in Lakewood, Colorado, on November 7, 2014. Sponsored by the Geo-Institute Chapter of the Colorado Section of ASCE, the Rocky Mountain Section of the Association of Environmental and Engineering Geologists, and the Colorado Association of Geotechnical Engineers Geotechnical Practice Publication No. 9 contains 11 papers that address the complex geotechnical challenges in geologic hazards, nondestructive evaluation, geo-construction, and the ground itself. Topics include: seepage reduction on dams and levees; debris flow risk assessment; testing rockfall barrier systems; landslide hazard ranking and remediation; collapsing soils; ground classification system for excavations; and flooding impacts on Left Hand Creek. GPP 9 focuses on Colorado and the Rocky Mountain West s specific geotechnical practice and experience. It will be valuable to anyone in geotechnical engineering, especially those working in similar geologic settings.
