ABSTRACT
This chapter aims to present strategies for monitoring and modelling of slope response to climate changes. Soil moisture variation in time within slopes is recognized as a major source of uncertainty concerning the safety conditions of any slope. The slope responses were characterised through measurement of the following variables: rainfall inputs to the slopes runoff generation from the slopes and changes in pore-water pressures in response to rainfall. Slope responses to rainfall were assessed through the pore-water pressure changes in the slope. The tensiometer readings from the slope crest were plotted with the corresponding rainfall readings to indicate the seasonal pattern of pore-water pressures at Yishun slope. The results of natural and simulated rainfall runoff experiments conducted on the test slope suggest that a large proportion of the rainfall contributes to infiltration in the residual soil slope.
