پایش عوامل اقلیمی مؤثر بر پدیده گرد و غبار و ماسه های روان ( فرسایش بادی ) با شاخص لنکستر در استان تهران

The phenomenon of climate change is one of the most important environmental challenges in the world, which has increased its speed with the increasing emission of greenhouse gases and remote communication phenomena. Among the known factors caused by climate change, we can mention the change in the amount of rain, the increase in the occurrence of droughts and desert areas, and the change in the level of surface and underground water resources. To investigate the effect of climate change, especially wind and rain, on the activity of sands and in order to predict the possibility of the movement of sand dunes and sand dunes and the dust caused by them using a global method. Lancaster is used. This method can be used to predict the movement of sand dunes and sand dunes in the coming decades. shows After calculating the mobility index of sands for different regions of the country, the values obtained in the graph that will be introduced for this purpose, their activity index are compared and prioritized and finally, if necessary, with The use of sensitivity analysis of the effects of climate change in the stabilization or movement of sand dunes will be predicted in the future.
