Improving groundwater project analysis with geophysical data

摘要

When interpreting the earth's subsurface for groundwater contamination, we face a fundamental problem — we typically sample one-millionth of the relevant material. If only these data are used to determine the material between boreholes and the continuity of high hydraulic conductivity units, the answers will be ambiguous For example, consider a site where three boreholes intersect two hydro-facies (Figure 1). If no other information is available, all of the interpretations shown (and many more not shown) are equally likely.
