文摘
Root water uptake modeled at meso- (single-root) and macro- (root-system) scales.
Results of RWU modeling confronted with sap flow and tensiometric data.
Similar critical RWU rates found when different mesoscopic RWU models applied.
Transpiration rates found highly sensitive to root geometry/resistance characterization.
Equifinality problem detected for active root system parameterization.
