abstract in this research sand drifts potential using sand rose graph software and fryberger velocity classes’ method investigated. thus wind data between 1985 and 2005 from meteorological stations of jask and kerman were analyzed to examine sand drift potential. sand drift potential amount of kerman station was 412.6 using sand rose graph and 401.09 using fryberger,s method. sand drift potenti...

The majority of Iran’s area is covered by arid and semiarid climates. In these areas, wind causes more erosion compared to water. Therefore, determination of wind characteristics especially its velocity is very important. One of the simplest methods that can supply researchers with the origin of wind erosion in the shortest time is synthesizing sand rose model and interpretation of aerial photo...

erosion by wind is one of the most important factors in desert environment. prevailing winds can shift sand dunes and affect their accumulation. also, wind regime determines the direction of sand dune mobility. the aim of this research was to investigate sand drift potential using sand movement models. for this research, wind data between 1986 and 2005 from the meteorological station of yazd we...

the kashan erg is one of the most important sand dune complexes in iran. being affected by wind erosion, theerg's borderlands face numerous problems as a result of sand movement. to evaluate the risk of sands moving intoresidential areas near the kashan erg, anemometry data from synoptic stations located in kashan, ardestan, meimeh,naeen, and qom were collected and analyzed to calculate the san...

We present an interactive sand art drawing system using one RGB-D sensor, such as Kinect. Our system supports the common sand drawing functions, such as sand erosion, sand spilling, and sand leaking. To use hands to draw virtual sand on a drawing plane, we design four key gestures which enable drawing manipulation actions for sand. The basic idea is that the gesture of one hand controls the dra...

The physical development of cities is always faced with natural barriers. The physical development of the city of Zabol, located in the Sistan plain, is threatened specifically with the development of sand dunes. For this reason, the region’s drought conditions were investigated and the standardized precipitation index was calculated. The results showed that with the drying of Hamoon Lake, the ...
