Two-thirds of Singapore's land area is covered with residual soils from the Sedimentary Jurong Formation and the Bukit Timah Granite Formation. Rainfall-induced slope failures often occur in these residual soils as a result of tropical rainfall events. These slope failures can be dangerous, disruptive to the development of infrastructures and quite costly to repair. Therefore, it is timely and appropriate that a better technology for preventing these failures be developed with special consideration being given to the local climate and geology. This appropriate technology can be developed only if the mechanism of rainfall-induced slope failures is properly understood.
