A systemic framework for mathematical modeling of Soil-Tree system is proposed through this work. The model couples the vadose zone moisture uptake by trees with the cumulative multi-layered canopy water demand. The water demand is estimated by integrating the photosynthesis models and stomatal conductance with the leaf energy balance. The philosop...
