Description :
This paper presents a method that uses Geographic Information System (GIS) to assess geological hazards, vulnerability, and risk in the Glenwood Springs area. The hazards evaluated include subsidence, rockfall, debris flows, and floods. The AA. focus on debris flows and subsidence. Information on topography, hydrology, precipitation, geomorphic processes, bedrock and surficial geology, structural geology, soils, vegetation, and land use, was processed for hazard assessment using a series of algorithms. ARC/INFO and GRASS GIS softwares were used to produce maps and tables in a format accessible to urban planners.
