| description abstract | Root water uptake is often modeled as a sink term in the Richards equation to account for evapotranspiration losses. The sink term is assumed to be a power law function in the nonlinear root uptake model (O-R model) to account for the decrease in root density and water uptake with depth. In order to extend the O-R model to other crops without requiring detailed and time-consuming experiments, two important dimensionless numbers (specific transpiration, | |
