Abstract :
This study was carried out to investigate the impacts of Karoun water branches transference projects on creation or intensification of Khuzestan dust points. For this purpose, daily climatic parameters (temperature, precipitation, horizontal view, moist and wind) and required water debit for 9 synoptic and hydrometric stations within a 30-year statistical period were collected. Missing data were recovered and sorted by using Matlab,Minitab and Excel software. Also satellite data and images were used to study vegetation, soil moist and dust particles conditions in the specific area. According to the greenhouse gas procedures during 1985 to 2015, the studied period was broken into two periods, one before global warming (1985-1995) and the other after intensification of global warming (1996-2015). Then by using statistical methods and remote sensing the mentioned periods were investigated. The results from investigating long term debit of Karoun river showed that there is 171 m3/s decrease in second statistical period than the first one. During the second period, local dust has increased in comparison with the first period but vegetation index (NVDI) has 13% decrease. Also the vastness and value of soil moist in east of basin have increasing trend and the role of dam construction is evidently influential. This trend has been decreasing around Shadegan wetland in west of basin, as the result, with passing flows over this area, because of adherence reduction, soil particles disserve from the ground and cause most of the dust in Khuzestan and Karoun riverbasin.
