The Impact of Dam Construction in Turkey on the Intensity and Frequency of Dust Events in Western Iran
, M.Sc. Thesis Sharif University of Technology ; Danesh Yazdi, Mohammad (Supervisor)
Abstract
This study analyzes the impact of climate-related stressors and water resources development projects in the Tigris-Euphrates Basin on regional dust storm intensity and frequency. To this end, we utilize remote sensing data for Aerosol Optical Depth (AOD), wind speed, surface temperature, soil moisture, precipitation intensity and inter-arrival time, Standardized Precipitation Evapotranspiration Index (SPEI), and vegetation cover to explore long-term trends. To identify dust hotspots, we introduce a normalized intensity-frequency index (NIFI). The NIFI combines the arithmetic mean of AOD values and the frequency of daily AOD measurements exceeding a predefined threshold, to identify potential...
