Abstract

This article investigates the correlation between the potential for sand encroachment on a newly
constructed railway line and the annual precipitation levels. An expert survey was conducted among
specialists directly and indirectly involved with this issue, alongside a statistical analysis of natural and
climatic winter-spring precipitation over several years in regions where the under-construction railway
intersects dune sands. The annual precipitation data were compared with the occurrence of sand drifts.
The results of the expert survey, monitoring of potential railway sand encroachment, and precipitation
analysis are presented. It was established that the manifestation of sandstorms, and consequently the
potential for sand encroachment on infrastructure, is dependent on the amount of rainfall during the
winter-spring period. Utilizing the findings of this research will enable the elimination of unnecessary
annual measures for protecting the new railway line from sand drifts, specifically those related to the
stabilization of mobile sands.
