Integration of wind and drifting snow numerical models in GIS snowdrift riskk on roads: A tool for engineering

Snowdrift problems concern many regions in France. They have significant economical consequences because this phenomenon may stop traffic. The paper deals with a first prototype of an almost automatic tool, which will help any user to locate risks of snowdrift on roads. It has been developed in a Geographic Information System (G.I.S) using wind and drifting snow numerical models realized in our team. Both numerical models integrated in this GIS can be used by road engineers to localize the different road cut sections where drifting snow will occur and to determine snowdrift shape. In order to reduce the duration of computation, the wind (3D) is calculated on a large area including the road and the drifting snow model (2D) is only used in some problematical road cut sections. After a general description of the context, this article describes: (1) the used numerical models; (2) their integration in a GIS; and (3) an example of application on a new highway in the centre of France.
