      abstract     = {A saline tracer infiltration test across the fractured
                      vadose zone of an industrial contaminated site in Belgium
                      was monitored by combining surface and cross-borehole
                      electrical resistivity tomography (ERT) methods with a
                      vadose zone monitoring system (VMS). The VMS provides in
                      situ continuous hydraulic and chemical information on the
                      percolating tracer at multiple depths in the vadose zone.
                      The combination of such high-resolution data with time-lapse
                      geophysical images that capture the spatiotemporal
                      variability of the subsurface improves interpretations of
                      flow and transport, providing a better characterization of
                      infiltration mechanisms and preferential flow paths. The
                      tracer infiltration test was performed over a heterogeneous
                      vadose zone composed of backfilled materials, sands and
                      silts, and unsaturated fractured chalk. Monitoring results
                      during a 5-d period revealed the formation of a tracer plume
                      in the upper backfilled deposits, while some of the tracer
                      migrated laterally following preferential pathways. Slow
                      vertical flow through matrix pores was found to be dominant
                      under dry conditions. Infiltration of small quantities of
                      rain during the test was found to have an influence on the
                      spatial distribution of the plume. Results from long-term
                      monitoring revealed vertical transport of the tracer toward
                      depths that reached 4 m during a time period of 105 d.
                      During that period, fracture and matrix flow mechanisms
                      across the vadose zone were activated as a response to
                      frequent rainfall episodes. The study demonstrates that the
                      interpretation of geophysical images is improved by in situ
                      information from the VMS.},
