      abstract     = {This study tested a method to quantify and locate hydraulic
                      lift (HL, defined as the passive upward water flow from
                      wetter to dryer soil zones through the plant root system) by
                      combining an experiment using the stable water isotope 1H2
                      18O as a tracer with a soil–plant water flow model. Our
                      methodology consisted in (i) establishing the initial
                      conditions for HL in a large rhizobox planted with Italian
                      ryegrass (Lolium multiflorum Lam.), (ii) labeling water in
                      the deepest soil layer with an 18O-enriched solution, (iii)
                      monitoring the water O isotopic composition in soil layers
                      to find out changes in the upper layers that would reflect
                      redistribution of 18O-enriched water from the bottom layers
                      by the roots, and (iv) comparing the observed soil water O
                      isotopic composition to simulation results of a
                      three-dimensional model of water flow and isotope transport
                      in the soil–root system. Our main findings were that (i)
                      the depth and strength of the observed changes in soil water
                      O isotopic composition could be well reproduced with a
                      modeling approach (RMSE = 0.2‰, i.e., equivalent to the
                      precision of the isotopic measurements), (ii) the
                      corresponding water volume involved in HL was estimated to
                      account for $19\%$ of the plant transpiration of the
                      following day, i.e., 0.45 mm of water, and was in agreement
                      with the observed soil water content changes, and (iii) the
                      magnitude of the simulated HL was sensitive to both plant
                      and soil hydraulic properties.},
