Analyzing meteorological risks to highway infrastructure in Saskatchewan by Monirul Islam, Golam Kabir, Muhammad Rehan Anis

“…However, its sustainability is increasingly challenged by meteorological hazards. This study conducts a detailed spatial risk assessment of Saskatchewan’s major highways by analyzing six climate-related factors: flood-prone areas, precipitation mm d ^−1 ), snowfall (cm d ^−1 ), extreme temperatures (minimum and maximum in °C), and wind (maximum gust speed in km h ^−1 ). …”
