Temporal and Spatial Analysis of Dust Occurrence in Lorestan Province

Today, dust risk management is critical global challenge, especially in the Middle East. The aim of this study is to analysis temporal and spatial changes of dust occurrence in Lorestan province. This analysis used for risk control and adaptation to achieve sustainable development areas.

Changes in dusts were analyzed during a 17-year period (2000-2016) for 8 synoptic stations. Best model, with lowest MAE and RMSE, was selected for analyzing spatial variations. The CoKriging model interpolation was used to provide dust risk map. Then, this map converted in to a pixel grid in ArcGIS software.

The results of annual dust survey show that Khorramabad station had the highest number of days with the average frequency of 16 days in year. The highest frequency of dust storms was in June and July whiles the lowest was in November and December. The results of risk zonation mapping that about 21 And 71 percent of the region has a high risk of the dust storm in term of below 10 and one kilometer of horizontal visibility, respectively.

Due to the high risk of dust, it is possible to provide prevention and control programs and also compatibility of the regional development goals with Iran land use planning and conservation and restoration of soil and water resources in order to achieve the preventing desertification and climate change. This research with a promising and pragmatic approach has provided a remarkable description to policy makers, managers, and other natural disaster stakeholders in the of Lorestan province development.
