EG-14 Collapsible Soils in Colorado


2 in stock

Collapsible Soils in Colorado describes the geologic setting, the geomorphic and soil conditions, locations of potential susceptibility, and engineering properties of collapsible soils in Colorado. This bulletin is the result of a comprehensive and multi-year effort to understand collapsing soil behavior and the geologic and geomorphic conditions where they can form. In addition, this report contains a 1:1,000,000-scale map of Colorado that shows locations of soil collapse compiled from soil test data and damage incidents, climatic exclusions zones, and areas of the state where collapse-prone soil may exist. 108 pages, spiral-bound, 1 plate. EG-14

The objective of the CGS collapsible soil program is to increase the public and professional awareness of collapsible soils in Colorado; and to improve the existing geological and geotechnical professional standard-of-practice through the discussion and evaluation of the tools and techniques that are available to investigate and assess what is a widespread geologic hazard, common in almost all semi-arid non-mountainous areas of Colorado.

UPDATE: The Association of American State Geologists announced that their annual John C. Frye Memorial Award for 2009 is granted to the CGS and the staff members who authored EG-14.
