Model(s) for the dispersion of hazardous substances in floodwaters for RAPID-N
Floods can impact hazardous industrial installations where they can cause the release of hazardous substances and lead to pollution, fires or explosions. While research about the dispersion of pollutants in water bodies is available, there is little knowledge about the dispersion of pollutants in and with the floodwaters. This study aims to address this topic, as well as explore the feasibility of implementing oil and chemical spill models into the JRC’s RAPID-N system for rapid Natech risk assessment and mapping to expand its capabilities related to consequence modelling for flood-triggered Natech events.
The study comprises the collection and description of candidate models for the dispersion of chemical and oil substances in floodwaters, as well as a review on the feasibility of their integration in RAPID-N. A group of oil spill models that were considered fit for integration into RAPID-N were shortlisted. No chemical spill model was found to be eligible.
This study also investigated the integration of a candidate pollutant dispersion model in floodwaters into RAPID-N. Three possible approaches were investigated. While in principle technically feasible, all approaches are complex and costly in terms of required resources, time and expert knowledge. The most promising solution identified would be running a dispersion model on an external service which links to RAPID-N.
