Risk Assessment Of Sloping Land Using Gis-Based Mapping, Phil N. Flentje, Robin N. Chowdhury
Risk Assessment Of Sloping Land Using Gis-Based Mapping, Phil N. Flentje, Robin N. Chowdhury
Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, attention is drawn to GIS-based techniques for mapping and risk assessment for slopes and landslides. The authors focus on an approach developed recently for mapping of geology and slope stability in the Northern Illawarra (or the Northern Suburbs of Greater Wollongong Area) in New South Wales, Australia. The use of databases of geology and land instability and use of other GIS-based information relevant to sloping land for the development of a valid hazard and risk assessment procedure is explored. The developed approach will be applicable to other sloping areas and, in particular, urban areas both nationally and …
Geological And Land Instability Mapping Using A Gis Package As A Building Block For The Development Of A Risk Assessment Procedure, R N. Chowdhury, P N. Flentje
Geological And Land Instability Mapping Using A Gis Package As A Building Block For The Development Of A Risk Assessment Procedure, R N. Chowdhury, P N. Flentje
Faculty of Engineering and Information Sciences - Papers: Part A
A modern land instability risk assessment procedure must include an accurate geological framework and land instability database. Geological and land instability mapping of the northern suburbs of the City of Wollongong represents a considerable challenge and is to be achieved using computer generated 1:4000 topographic base maps. Using an integrated series of techniques, including computer modelling of the escarpment geology and field mapping techniques, a new series of geological maps has been produced. Meanwhile an exhaustive land instability database of the region has been compiled. A flexible approach to mapping and data compilation is very useful and confirms the viability …
