Abstract
Tree failure in Singapore commonly occurred during or after heavy rainfall. This incidence could cause economic losses and even serious casualties. However, the relationship between a rainfall event and a tree failure has not been well understood. This study presents details of a field monitoring program used to investigate the water flow characteristics in the soil around a tree during and after rainfall. The results of the study were then used for assessment of tree stability. Data from a specified period of field instrumentation were used for limit equilibrium analyses. The analyses showed that the matric suction in the soil decreased during rainfall and as a result, the shear strength of the soil decreased. The reduction in shear strength of soil led to a decrease in tree stability.
