Resilience And Sustainability In The Management Of Landslides, Phillip N. Flentje, Robin N. Chowdhury
Resilience And Sustainability In The Management Of Landslides, Phillip N. Flentje, Robin N. Chowdhury
Faculty of Engineering and Information Sciences - Papers: Part A
There are many regions worldwide which are susceptible to landslides, which cause loss of life and adverse impacts to infrastructure, environment and communities. Landslides are often triggered by exceptional rainfall and large-magnitude earthquakes. A range of strategies and methods have been developed to mitigate the occurrence of landslides and to reduce their impact, including risk to human safety. The adopted approaches and systems must be sustainable and resilient in relation to the communities that are at risk. This paper refers to an Australian regional case study of urban landslide management in the Wollongong region, New South Wales. The research carried …
An Inventory Of Landslides Within The Sydney Basin To Aid The Development Of A Refined Susceptibility Zoning, Phillip N. Flentje, David Stirling, Darshika Palamakumbure
An Inventory Of Landslides Within The Sydney Basin To Aid The Development Of A Refined Susceptibility Zoning, Phillip N. Flentje, David Stirling, Darshika Palamakumbure

The University of Wollongong GIS-based Landslide Inventory is currently being expanded from its Illawarra centric coverage (664 landslides) to include the 31,000km2 geological extent of the Sydney Basin and ultimately all of New South Wales (hereafter this inventory will be referred to as the NSW LI). In 1998, this inventory stood at 319 sites of instability and in 2010 it had grown to 616 landslides. The population of the Sydney Basin in 2006 was approximately 4.9 million people, representing approximately one quarter of the population of Australia. When this current phase of expansion is completed, the NSW LI will include …
Consideration Of Probability Assessments Relevant To Hazard And Risk For Landslides, R N. Chowdhury, P N. Flentje
Consideration Of Probability Assessments Relevant To Hazard And Risk For Landslides, R N. Chowdhury, P N. Flentje
Faculty of Engineering and Information Sciences - Papers: Part A
Probability of occurrence is the most important component of landslide hazard and risk and this paper outlines different approaches for its assessment. The reasons for the popularity of qualitative approaches are first outlined. Quantitative approaches can be best applied if the important influencing factors and issues are fully understood. Formal probabilistic approaches are often based on geotechnical models or on a combination of hydrological and geotechnical models. The paper also highlights the situations for which the performance function must be formulated in terms of lateral displacements rather than the conventional safety factor. Reference is then made to a procedure, based …
Geotechnical Assessment And Management Of 148 Landslides Triggered By A Major Storm Event In Wollongong, Australia, P N. Flentje, R N. Chowdhury
Geotechnical Assessment And Management Of 148 Landslides Triggered By A Major Storm Event In Wollongong, Australia, P N. Flentje, R N. Chowdhury
Faculty of Engineering and Information Sciences - Papers: Part A
On the 17th August 1998 a severe rainfall event occurred over a widespread area of the City of Wollongong. During this storm, 1 person drowned and an estimated $50 to $100 million damage was caused to the City of Wollongong. Road access to the City was cut by raised water levels and debris flows covering and or scouring road and rail routes for up to 36 hours following this event. A geotechnical team of 3, including the first author, was organised at very short notice during the response phase of the emergency operations on the early morning of the 20th …
