Popis

The false-color composite image of the Death Valley regional ground-water flow system (DVRFS), an approximately 100,000 square-kilometer region of southern Nevada and California, was derived from Landsat 5 Thematic Mapper (TM) data for 1996. The image is a composite of spectral bands 2, 4, and 7 in RGB (Red-Green-Blue) space. Individual bands were processed to display their full dynamic range. The image was further processed in hue-saturation space to emphasize specific geologic features. The image was a base reference for field reconnaissance work and for developing of the DVRFS transient ground-water flow model. The DVRFS flow model is one of the most recent in a number of regional-scale models developed by the U.S. Geological Survey (USGS) for the U.S. Department of Energy (DOE) to support investigations at the Nevada Test Site (NTS) and at Yucca Mountain, Nevada (see "Larger Work Citation", Chapter A, page 8).
