The Application of Geomorphological Mapping in the Assessment of Landslide Hazard in Hong Kong

Abstract In 2008 the Hong Kong Government commenced a 10-year programme of assessing natural slopes potentially affecting existing developments. Such studies require a high level of engineering geomorphological input to examine landscape evolution, understand past and present geomorphological processes and establish applicable hazard models as a basic framework for landslide hazard and subsequent risk assessment. This case study outlines the geological and geomorphological setting of Hong Kong, discusses the current landslide risk guidance in Hong Kong, outlines the importance of geological and geomorphological models to provide a framework for the assessment of landslide hazard and discusses the critical role of engineering geomorphological mapping in evaluating the model and in producing a defensible design event.
