Direct Current Resistivity Profiling to Study Distribution of Water in the Unsaturated Zone Near the Amargosa Desert Research Site, Nevada. | |
Abraham, J. D; Lucius, J. E. | |
英文摘要 | In order to study the distribution of water in the unsaturated zone and potential for ground-water recharge near the Amargosa Desert Research Site south of Beatty, Nevada, the U.S. Geological Survey collected direct-current resistivity measurements along three profiles in May 2003 using an eight-channel resistivity imaging system. Resistivity data were collected along profiles across the ADRS, across a poorly incised (distributary) channel system of the Amargosa River southwest of the ADRS, and across a well-incised flood plain of the Amargosa River northwest of the ADRS. Subsurface profiles of resistivity produced from these data indicate three categories of materials: 1) laterally extensive very-dry, high-resistivity (> 150 ohm-m) materials at the surface, 2) localized regions of higher-water content, and lower-resistivity (< 40 ohm-m) materials below the surface in active recharge areas (beneath the Amargosa River), and 3) laterally extensive areas of intermediate water content and resistivity values. |
