      abstract     = {Three dimensional soil-root water transfer models require a
                      fine soil and root discretization in order to obtain
                      accurate results. This goes along with a considerable
                      computational effort. One way of reducing the computational
                      effort is the usage of grid refinement techniques. With such
                      techniques irregular grids are obtained that combine the
                      accuracy of a fine grid resolution with a considerable
                      reduction in computational costs. As a consequence of plant
                      transpiration roots take up water and large soil water
                      potential gradients around roots are created. Especially in
                      these regions a fine soil discretization is needed. The root
                      spatial distribution can therefore be used for refinement of
                      the soil grid, a priori. Simulations show that the accuracy
                      is indeed maintained for a priori refined grids but with
                      reduced computational costs as compared to regular fine
                      grids. Comparison with a well recognized a posteriori error
                      estimate strengthen these results.},
