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 ...

The goal of this study was to provide quality assurance for QuikSCAT wind speed and direction in Iranian adjacent seas including the Caspian Sea, the Persian Gulf and the Gulf of Oman. Synoptic station wind data and numerical atmospheric models in the study area were compared with QuikSCAT wind field. Time difference and spatial separation between the QuikSCAT and synoptic observations were lim...

Wind is one of the important natural phenomena in arid and semi-arid ecosystems of the world. Although several studies have been conducted using the wind speed and direction to provide wind rose in each area, only a few of them investigated the possibility of wind speed at different return periods. Analysis of the maximum wind speed at different return periods, in a variety of projects such as ...
