abstract = {In this manuscript, we propose a new method to calculate
water flow and xylem water potential distribution in
hydraulic architectures (such as root systems) of any
complexity. It is based on the extension of the water flow
equation analytical resolution of Landsberg and Fowkes for
single roots. It consists in splitting the root systems in
zones of homogeneous or homogeneously changing properties
and deriving the xylem potential and water flow under any
given boundary conditions (plant transpiration or collar
potential, and potential at soil-root interfaces) without
assuming a uniform xylem potential within each zone. The
method combines analytical solutions of water flow within
the segmented zones with the numerical solution of flow
connectivity for the whole root system.We demonstrate that
the proposed solution is the asymptote of the exclusively
numerical solution for infinitesimal root segment lengths
(and infinite segment number). As water uptake locations and
magnitudes predicted by the latter solution for finite
segmentation lengths deviate from the exact solution, and
are computationally more intensive, we conclude that the new
methodology should always be privileged for future
applications.The proposed solution can be easily coupled to
soil modules (as already done with existing solutions) and
further implemented in functional-structural plant models to
predict water flow in the soil-plant atmosphere continuum
with a better accuracy than current models. Finally the new
solution may be used to calculate more accurately plant
scale macroscopic parameters for crop models.},
