The environmental sub-model of the Swedish Winter Model from real world data to a modelled scenario
2006 (English)Report (Other (popular science, discussion, etc.))
The use of salt in the winter maintenance operations has both desired and undesired consequences. Many studies have been made regarding different environmental problems related to road salt. Most of the studies regarding salt damaged vegetation have however been concerned with the concentration of sodium and chloride in plant tissue, an indicator not very useful for the road administrator. The main purpose of the environmental sub-model of the Swedish Winter Model is to increase knowledge regarding the relationship between salting (amount, method, technique and timing) and the roadside exposure at different distances. Given known or assumed dose-response relationships for certain types of vegetation, the damage can also be modelled. And, by setting a cost for this damage, at least parts of the environmental costs can be estimated. Since the model works in a high time-resolution (one hour) during the winter season, it can be used to test scenarios where for instance the maintenance regulations, the traffic composition or the climate have changed.
