Geospatial Analysis and Knowledge Discovery: Complementary Perspectives using Statistical and Machine-learning Techniques

15. April 2013, Alexander Brenning

Novel analysis and prediction methods developed at the intersection between computer science and statistics have been gaining popularity in recent years in quantitative (physical  and human) geography and remote sensing. These newer approaches promise to improve predictive performances by overcoming the limitations of statistical models, and to better represent complex social and environmental processes. ... more

Development of a spatial decision support system for analyzing changes in hyrdo-meteorological risk

8. April 2013, Cees van Westen

The analysis of the effect of risk reduction planning alternatives on reducing the risk now and in the future and the support of decision makers in selecting the best alternatives is of highest relevance. Herein, Spatial Decision Support Systems SDSS are most promising. ... more

Mitigating the Risk from Lahars on Ruapehu Volcano, New Zealand

29. November 2010, Harry Keys

Hazardous lahars occur about every decade on average on the active glacierised Ruapehu Volcano (2797m, winter snowline 1600-1700m) in New Zealand. It is the nation’s singly largest centre for mountain recreation, particularly skiing and snowboarding. ... more

Early Warning Systems for Natural Hazards - The Fundamentals

15. November 2010, Tad Murty

Natural hazards can be broadly grouped into three types: (A) Permanent, (B) Evanescent and (C) Episodic. A dominant feature in almost all types of geophysical data records is the so-called clustering effect. ... more


Guest Lectures 2008

Emergence and Complexity

10. November 2008, Stephan Harrison

Emergence is a characteristic of dynamic systems where the large-scale
behaviour of the system is effectively independent of the behaviour of the smallscale components of that system. Scientific attempts to unravel the complexity of complex systems have tended to follow reductionist paths ... more

Mutliple occurance regional landslide events as a formative geomorphic process

14. April 2008, Nick Preston

Mass movement can be shown to be the dominant geomorphic process in many parts of New Zealand. Of particular importance are episodes of extensive slope failure associated with intense rainfall and seismic triggers ... more

Engineering Geomorphology

21. Jannuary 2008, Roger Moore

Engineering Geomorphology is a specialist discipline of the earth sciences and its value in the commercial world has not always been recognised. The talk will illustrate several major projects where engineering geomorphology, high-quality remote sensing data ... more
