A methodology for physically based rockfall hazard assessment

A methodology for physically based rockfall hazard assessment

Rockfall hazard assessment is not simple to achieve in practice and sound, physically based assessment methodologies are still missing. The mobility of rockfalls implies a more difficult hazard definition with respect to other slope instabilities with minimal runout. Rockfall hazard assessment involves complex definitions for “occurrence probability” and “intensity”. This paper is an attempt to...

GIS-Based Rockfall Hazard Assessment in Support of Decision Making

When designing infrastructure, settlements or facilities in mountainous areas, rockfall hazard assessment is considered essential, as it is a major hazard worldwide. Rockfall hazard estimation can help greatly in the design of countermeasures, such as barriers and net fences, in order to protect the built environment, as well as for landuse planning. Rockfall modelling is considered an effectiv...

The Evolution of HAZARD, the Fire Hazard Assessment Methodology

The United States alone spends about $700B per year on new and renovated construction. About 20% of this is to assure safety from unwanted fires, which includes the cost of insurance, to make families whole after fires and to recover from business loss. This is an enormous cost to endure every year. Combined with a growing construction market in other countries, this presents a major opportunit...

Erosion Hazard Index Methodology (EHIM) for Streams Erodibility Assessment (Ardabil-Province)

An erosion hazard index methodology (EHIM) was developed for assessing stream erosion. The index of stream erosion is designed as a management tool. Assessing stream erosion involves consideration of a range of aspects of streams and a value judgment about a desirable state. The assessment of the erosion indicators of streams was based on a state-wide assessment of physical stream condition. A ...
