Hydrus-1D Projects – Root Uptake

  • Project Group: Roots
  • Description: Examples demonstrating the use of the new root water and solute uptake term (which includes both compensated and uncompensated root water and solute uptake, and both passive and active root solute uptake (from Simunek and Hopmans, 2009)

Project Description
Root1 Non-compensated root water uptake, groundwater lever at the 120-cm depth.
Root2 Compensated root water uptake (critical stress index=0.75), groundwater lever at the 120-cm depth.
Root3 Compensated root water uptake (critical stress index=0.5), groundwater lever at the 120-cm depth.
Root4 Non-compensated root water uptake, groundwater lever at the 120-cm depth, daily variations of transpiration generated by HYDRUS.
Root1S1 Same as Root1 with no solute uptake.
Root1S2 Same as Root1 with unlimited passive solute uptake.
Root1S3 Same as Root1 with unlimited passive and non-compensated active solute uptake.
Root1S4 Same as Root1 with unlimited passive and compensated (critical stress index=0.5) active solute uptake.
Root1S5 Same as Root1 with only non-compensated active solute uptake.
Root1S6 Same as Root1 with only compensated (critical stress index=0.5) active solute uptake.
