Effective Urban Landslide Hazard Assessment, Robin N. Chowdhury, Phillip N. Flentje
Effective Urban Landslide Hazard Assessment, Robin N. Chowdhury, Phillip N. Flentje
Faculty of Engineering and Information Sciences - Papers: Part A
Landslide hazard assessment is a vitally important component of any strategy for the management of risk of instability in hilly areas. Within many urban areas, reactivation of landslides is an important component of risk. Yet, most qualitative approaches do not differentiate between the hazard of individual landslides. Two quantitative approaches are introduced in this paper both of which utilise GISbased accurate maps of geology and landslip as well as a landslide database. The first method is based on historical recurrence of individual landslides. The second method is based on monitoring of subsurface shear movements, and their relationships to rainfall. Both …

A Landslide Database For Landslide Hazard Assessment, Robin N. Chowdhury, Phillip N. Flentje
Faculty of Engineering and Information Sciences - Papers: Part A
Assessing the hazard and risk of slope instability and landsliding requires a consideration of basic geological and geotechnical factors which control stability as well as external agents or events which decrease stability and which may trigger landsliding. Prediction of slope performance is difficult and it is, therefore, considered appropriate to develop approaches for hazard and risk assessment. This paper is concerned primarily with one important aspect or element of such an approach. The essential and desirable features of a landslide database are outlined with particular reference to an urban area in New South Wales, Australia. The procedures and processes for …
