SCOTT WILSON (Hong Kong) has been commissioned by the Hong Kong Geotechnical Engineering Office to carry out further study of landslides on natural ground as part of its Natural Terrain Landslide Study.
With continued expansion of the SAR into previously undeveloped areas, concerns have been increasing over the stability of natural slope failures. The latest project hopes to help develop a risk management strategy of these features.
The project will update the Natural Terrain Landslide Inventory (NTLI) with landslide events since 1995. High level aerial colour photography taken between 1995 and 1997 will be studied, identifying slope failures, digitising them and putting them on the NTLI database.
The team also aims to identify and form a classification of large landslides in the region. For this, mainly black and white low level aerial photographs taken in 1963 and 1964 will be studied. Events since 1964 will also be reviewed as part of the study.
