Engineering geologic mapping and potential geologic hazards in Colorado
Summary Land-use planning requires identification of areas where geologic conditions may be adverse to development and construction. In montane Colorado, where long-term experience with geologically hazardous conditions is usually not available, development accompanying increasing population necessitates engineering-geologic studies that contain predictive modelling of situations that may be encountered if geologically hazardous areas are inhabitated. Some hazardous geologic conditions in Colorado are unstable slopes, hydrocompactive soils, surface subsidence over abandoned underground mines, and fluvial processes related to water flooding. Traditional mapping of such categories usually involves recompilation of existing geologic map data in an engineering-geology format. The resulting map presents a correlation of generalized engineering properties with map units, leaving judgments about potential hazards entirely to the map user. An alternative approach to mapping these kinds of hazard-prone areas uses map units based primarily on the nature of the potential hazards associated with them. The map and its explanation are then combined with a land-use-type/geologic-hazard-area matrix that indicates engineering problems likely to be encountered in the mapped area, shows effects of local changes in slope and mechanical properties of soils and rocks, and generally evaluates hazard severity for various land uses.
