      abstract     = {Commercial cultivation of date palms has high economic
                      significance, particularly in arid and hyper-arid regions.
                      Achieving commercially viable yield of dates amid water
                      scarcity and enforced restrictions on water use requires
                      optimising the amount and timing of irrigation. To that end,
                      better understanding of the temporal dynamics of the water
                      use of date palm is of great importance. Traditionally, this
                      can be achieved through sap flow estimates obtained using
                      heat dissipation probes. However, such measurements lack the
                      ability to provide information on the spatial distribution
                      of sap flow, which is important considering that date palms
                      transport water in the entire stem cross-section. The aim of
                      this study is to evaluate whether electrical resistivity
                      tomography measurements have the potential to provide
                      information on the spatial variability of flow in date palm
                      stems. For this, flow was induced through a stem segment
                      that was obtained from a felled date palm tree. ERT
                      measurements were continuously obtained throughout a cycle
                      of flow and no-flow periods. The results showed that the
                      mean bulk electrical conductivity varied strongly due to
                      changes in the flow conditions. In addition, it was found
                      that the electrical conductivity of the outflow was much
                      higher than that of the inflow, which indicates the release
                      of stored salt from the stem segment. Analysis of the
                      spatial distribution of the electrical conductivity
                      suggested that flow mainly occurred in a limited part of the
                      cross-sectional area of the stem. Overall, it was concluded
                      that the ERT is a promising tool to investigate the spatial
                      variability of water flow in date palm stems.},
