Summary

Heavy rainfall runoff is one of the natural hazards that cause damage to the railway infrastructure: erosion of the railway subgrade, ballast carriage, flooding, and ballast pollution. Nowadays, this hazard is particularly difficult to predict and map, no explicit and reliable method exists for runoff hazard mapping. The SNCF Engineering Department began a research program to develop an operational mapping tool to improve prevention and mitigation of runoff impact on the railway system. The mapping is based on an innovative method developed by a French research institute (Irstea). This method maps the runoff sensitivity of catchments adjacent to route section. It is based on a spatial analysis of indicators such as topography, soil and land use. A new software was developed. The first step of the validation of this method in the railway context consists of comparing the results with historical incident records. It appears that most of the observed incidents caused by runoff are localized in or near the identified runoff hazard areas. The work, presented in this paper, opens up interesting perspectives for global solutions to runoff hazards assessment. They could cover various activities such railways platform design, maintenance plan and alert system for traffic safety.
