The effect of evapo-transpiration on the stability of mature trees

A tree’s stability largely depends on its root architecture as well as the soil properties it is grounded with. Numerical analysis was carried out using the SIGMA/W software, within the GEOSTUDIO suite of programs. The model was based on an experimental site located at Telok Blangah Rise where the t...
