Simulation de la teneur en eau dans le sol (DOY 200 à 204) avec irrigation et sans irrigation pour les différentes profondeurs du goutte à goutte enterré (15, 25 et 35 cm). L'arbre (positionné à r = 0) définit l'axe vertical de symétrie mis en œuvre dans le modèle. Le bulbe est généré par les goutteurs situés à r = 30 cm. Le bulbe vu en coupe occupe un cercle autour de l'arbre (goutteurs proches les uns des autres).

Simulation of soil water content (DOY 200–204) with irrigation and without irrigation for different depth placement of subsurface drip irrigation (15, 25 and 35 cm). The tree (positioned at r = 0) defines the vertical axis of symmetry implemented in the model. The wet bulb is generated by the emitters located at r = 30 cm. The wet bulb seen in section occupies a circle around the tree (emitters close to each other).
