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.
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.

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.
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. .
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.
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.
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
