      abstract     = {Monitoring the distribution of water content is essential
                      for understanding hydrological processes in the lithosphere
                      and the pedosphere. The movement of water in unsaturated
                      rock formations and in the vadose zone is influenced by
                      different processes (mainly infiltration, evaporation,
                      percolation and capillary flow) which may be rate
                      determining depending on the actual conditions. The
                      interdependence of these processes also strongly influences
                      the transport and distribution of solutes in the pore space.
                      In order to gain a better understanding of the movement and
                      distribution of water in unsaturated media, systematic
                      investigations with non-invasive or minimal invasive methods
                      appear to be most suitable. Studies on the distribution of
                      electrical conductivity can improve risk analysis concerning
                      waste disposals in general and nuclear waste repositories in
                      particular. Induced polarization and magnetic flux density
                      determined with two highly sensitive accessories yield
                      additional information and may allow for better
                      discrimination of coupled flow processes. Electrical
                      impedance tomography (Err) with 20 current injection and 48
                      voltage electrodes was used here to monitor the evaporation
                      of tap water from a container filled with sand under
                      laboratory conditions at 20 degrees C. The results are
                      compared with data obtained by determining spectral induced
                      polarization (SIP) of sand during desaturation in a
                      multi-step outflow equipment. Infiltration processes and
                      evaporation from sand saturated with 0.01 M CaCl2 were
                      determined by magneto-electrical resistivity imaging
                      technique (MERIT). The results were obtained from a
                      long-term experiment under controlled conditions. (C) 2010
