The impact of furrow on aeolian sediment transport, erosion, and granulometry changes (Case study: Nimroz city of Sistan and Baluchestan Province)

Currently, continued drought and accelerated desertification in the Sistan region have led to sandstorms and created environmental and humanitarian crises.This has not only devastated the region's ecosystem but also faced significant challenges to the lives of its residents.In addition, the consequences of these destructive phenomenon cause a lot of damage to urban and rural facilities and infrastructures.The most important factors affecting wind erosion in arid areas include low humidity, poor vegetation, destruction of soil structure (Physical and chemical) and flat land surface.In response to the dehydration crisis and the limitations of biological measures, as well as the prevalence of high erosive winds, increasing soil roughness by creating barriers to control the movement of soil and flowing sand is a practical approach to prevent the destructive consequences of wind erosion in this region.Hence, this research aims to investigate the effect of furrow on increasing soil roughness to control sand movement and reduce sediment transport in the wind erosion centers of the Nimroz City.
