THE EFFECT OF RAINWATER INFILTRATION WITHIN A SLOPE OF PYROCLASTIC DEPOSITS, RECORDED USING AUTOMATED ELECTRIC PROSPECTING

Rainfall and its infiltration into a slope is one of the most important factors affecting slope stability in a monsoon region. To understand the infiltration process, changes in the apparent resistivity within a slope in southern Kyushu, Japan, have been measured using automated electric prospecting. The slope studied is underlain by Quaternary weak and permeable pyroclastic flow deposits. Resistivity data obtained over a six month period indicate that the conditions within the slope vary and a distinct time lag is recognised between the rainfall event and the change in resistivity. At near surface depths the response is rapid and large. At lower depths it is slower and smaller, but the effects may be cumulative. (A)
