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)

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.
