Abstract

The analyses related to the selection of suitable adaptation measures for Singapore slopes showed that the 5-day rainfall scenario on low permeability soil has a lower FoS compared to the 1-day rainfall scenario on high permeability soil over all the different adaptation measures. This is because the prolonged period of rainfall allows more time for water to infiltrate the soil even at low permeability. Different adaptation measures have different capabilities in the prevention of rainfall-induced slope failure. The adaptation measures using vegetative cover, CBS, and GBS are recommended to achieve a minimum FoS of 1.25.
