The use of 3-D mapping in geological research and risksanalysis : evaluation of a water supply project in the Kathmandu-Melamchi area
Urban hazards and risks; consequences of large eruptions and earthquakes
to geological and geotechnical research and riskanalysis, concerns here the evaluation of the new water supply project Kathmandu-Melamchi proposed by WHO-UNDP and the World Bank.
Using 2-D and 3-D multi satellite data (SPOT and LANDSAT TM) in a GIS allows to produce 3-D digital elevation maps (DEM) through the techniques of remote sensing (RS) analysis and computer aided mapping. The use of 2-D and 3-D digital maps
Participatory community regeneration : a discussion of risks, accountability and crisis in devolved Wales

This article discusses participatory community regeneration programme through a discussion of risks, accountability and crisis in devolved Wales. The analysis shows how it became captured by a New Labour policy agenda shifting the priorities from
citizen representation to ‘community activation’ It also demonstrates that the state attempts to offset repeated failures to address economic crisis by a series of political-level ‘fixes’ fixes take the form of risk management measures, which the paper
discusses using the concepts of the risk society and reflexive government.
Geochemical Landscape Analysis: Development and Application to the Risk Assessment of Acid Mine Drainage. A Case Study in Central Sweden
; risk assessment
the complexity of pollution emissions and impacted landscapes. The objective of this paper is to link geochemical contaminant fate modelling and landscape analysis for the risk assessment of acid mine drainage along the source-pathway-receptor chain. A simple
Acid mine drainage containing toxic contaminants is a major cause of landscape degradation at numerous historic mine sites in Europe. Risk assessment of acid mine drainage and related polluted lands requires an approach that is able to study
geochemical landscape analysis tool is developed using landscape ecology spatial analysis and geochemical modelling methods. A case study is presented for the analysis of geochemical landscapes in central Sweden. Results show that the method can be used
efficiently for the risk assessment of toxic mine contaminants in the complex wetland landscape in the study area.
Flood frequency analysis : assumptions and alternatives
Flood frequency analysis (FFA) is a form of riskanalysis. The recent literature of FFA has been characterized by a proliferation of mathematical models used to extrapolate the return periods. This review in particular will consider the use
From an analysis of the response to fatal and non-fatal accidents, it is apparent that the accident record acted as an indicator of unacceptable behaviour and played an important role in risk management. Efforts to contain fatalities took the form
of sanctions and rules. Subcultural control over risk management weakened, and the stage was set for greater societal involvement. The AA. show the importance of the interaction of individuals, the subculture and society.

for the sensitivity analysis of spatial data in predefined classes. Several measures can be used to provide quality information that reflects the risk associated with the straightforward application of Boolean classes. The correct and unambiguous communication
The research underlying this Ph.D. thesis concerns the development of procedures for evaluating predefined classification techniques for spatial data. The definition of fuzzy sets and the analysis of fuzzy series are proposed as tools

Quantitative rockfall hazard and specific risk assessment of the selected municipalities within the České Švýcarsko National Park was performed using two rockfall hazard analysis modelling codes. CONEFALL and RockFall Analyst codes were used
to delimit rockfall hazard regions. Specific risk to buildings was consequently assessed using results from the hazard analysis and literature-derived vulnerability values. Results of hazard and risk assessments for two nearby municipalities were compared
Analysis of the institutional and social responses to the eruption and the lahars of Mount Pinatubo volcano from 1991 to 1998 (Central Luzon, Philippines)
Urban hazards and risks; consequences of large eruptions and earthquakes
Based on 3 viewpoints : from population, media and other actors, this analysis attempts to point out the strengths and weaknesses of the official management system, especially by studying the efficiency and the range of the solutions taken. So
, it appears that the management of the June 1991 main crisis (eruption) was a success, but difficulties have occurred with lahars risk management. In spite of persistent problems, the management system (monitoring/warning/evacuation) of lahar crises improves
Biophysical feedbacks and the risks of desertification
in dryland systems. This notion is tested by applying qualitative stability analysis of partially-specified systems. This analysis shows that a well-known model of biophysical feedbacks in dryland ecosystems is inherently unstable.
By frequency analysis we found some lows of probalities having regional character in the Depression of Transylvania : Log-Pearson III for monthly 24th max., Gumbel for annual 24h max. and Weibull for rain intensity. The suggested relationships
between the model parameters and the altitude emphasize that the risks of extremities depend on the first and second order relief, the shape of depression and the altitude. - (BJ)
