This report consists of two Special Project Reports on rainstorm runoff and infiltration on slopes in Hong Kong. They are presented in two separate sections in this report. Their titles are as follows:

Section 1 evaluates the effectiveness of various types of slope surface cover in generating rainstorm runoff based on field measurements at seven man-made slopes over a period of two years (1984 – 1985). The slope surface covers investigated were chunam, grass (both hydroseeded and turfed) and grass with shrubs and trees.

Section 2 presents and analysed the monitoring data of the six man-made slopes with different surface covers collected from 1986 to 1988. The data are also combined with the previous two years' records in Section 1 and re-analysed in order to derive conclusions from the full five years monitoring.
