Abstract
This report presents the findings of a detailed study of a cluster of over 45 natural terrain landslides that occurred in April 2000 and June 2001 in the vicinity of Cloudy Hill, Tai Po. The incidents ranged in volume from about 12 m3 to 630 m3 and consisted of debris slides, debris avalanches and debris flows, about 85 % of which became channelised. A high concentration of relict landslides was also identified in the Study Area.
The key objectives of the detailed study were to assess the characteristics of the landslides, mechanisms of failure and mobility of the debris following systematic collection of data. This was achieved through API study combined with engineering geological and regolith mapping and detailed inspection of selected landslides. The data have been interpreted with reference to spatial, topographical and geotechnical data, together with proposed geomorphological and landslide models of the natural terrain.
