Hazard analysis highlights the frequency and intensity of areas affected by floods, debris flows and landslides. The hazard map and technical report are the products of the analysis.

The guide consists of 4 parts. The main part "Manual Hazard Analysis" allows you to choose between a minimum standard and an advanced standard for the analysis.

The risk analysis highlights the expected damage to housing, infrastructure and property from flooding, debris flows and landslides. The risk analysis assesses whether the possible damage is acceptable or whether mitigation measures will be necessary.

In addition, the guide allows for the evaluation of the cost-effectiveness of mitigation measures by means of a cost-benefit analysis.

Methodological Guide Cost-Benefit Analysis of Measures Annex 1 – Risk and Cost-Benefit Analysis.xlsx
The Swiss Red Cross presents two methodological guides for analysing hazards, risks and the cost-effectiveness of mitigation measures. The guides are intended for risk managers in national societies and for commissioned consultants.
The analysis of natural hazards and risks is part of the baseline and endline of a project. The analysis reports on:
