Soil-water measurement technology developed for dry-soil investigations at the Amargosa Desert Research Site is being used by USGS and U.S. Army Corps of Engineers (USACE) scientists to assess the hydrologic performance of an evapotranspiration landfill cover at the U.S. Army Fort Carson military base, Colorado Springs, Colorado. The evapotranspiration landfill cover uses plants to control and prevent the downward movement of water. The soil-water measurement techniques provide a means to assess the performance of unconventional landfill covers that can be constructed at a considerably lower cost than conventional covers. USGS assistance to the U.S. Army Corps of Engineers (USACE) and their contractor has included calibration, installation, and instruction on the use of instruments. USGS is continuing to provide technical assistance through the review and interpretation of field data.
