Hazard assessment of debris flows for Leung King Estate of Hong Kong by incorporating GIS with numerical simulations

  title={Hazard assessment of debris flows for Leung King Estate of Hong Kong by incorporating GIS with numerical simulations},
  author={K. T. Chau and Kin Hing Lo},
As over seventy percent of the land of Hong Kong is mountainous, rainfall-induced debris flows are not uncommon in Hong Kong. The objective of this study is to incorporate numerical simulations of debris flows with GIS to identify potential debris flow hazard areas. To illustrate this approach, the proposed methodology is applied to Leung King Estate in Tuen Mun. A Digital Elevation Model (DEM) of the terrain and the potential debris-flow sources were generated by using GIS to provide the… CONTINUE READING
