Safeguarding Groundwater Resources: A View From Denmark

Successful practices to advance sustainable management around the world

Figure 1 - 3D visualization of results produced by a survey with the tTEM system. The figure shows variations in subsurface electrical resistivity, which can be interpreted as geological structures. High resistivities are shown as red and purple colors, which correspond to sand-rich deposits, whereas green and blue colors show low resistivity values corresponding to clay-rich layers.
