Abstract:
هذه الدراسة (اثر تغير المناخ في تغير مساحات الاهوار جنوب العراق (الناصرية، العمارة، البصرة) هي دراسة في علم المناخ التطبيقي (Applied Clomatology) اظهرت وجود تغير مناخي واضح في عناصر المناخ وظاهرة الغبار من خلال الاوساط المتحركة، والسلاسل الزمنية، وتحديد ا | This study concerned with the impact of climate change in the areas of marshes in Southern of Iraq( Nasiriya, Basrah and Omara).Is a study in applied climatology), showed the existence of clear climate change and dust phenomenon via the moving media and time series, and specifying the general trend and thorough statistic equitation, showed the existence of (C.V) between pre - drying period of marshes and after that , where it has been chosen Al - Nasiriya , Basrah and Omara) to represent the marshes state to follow - up their effects on the water climate balance , and studying the nature resources and water in come for Tigris and Euphrates rivers , also specifying time period ( 1941 - 2013) and analyzing them by quantities statistic, the study showed the existence of trend towards decline in number of solar radiation hours for all stations and showed the existence of clear indicators towards increasing mean air temperature and maximum and minimum temperatures especially after marshes drying , and wind speed are contrasted , in Nasriyah station trend towards decline clearly , and in Omara station , as for Basrah station trends towards increase and relative humidity towards decline in all stations , and Evaporation is also increased and variation the rain fall quantities where it declined in Basrah and Nasirya and increased in Omara station as for dust phenomenon where dust storm decreased and rising dust, decreased in Nasiriaya and Omara and increased in Basrh, and clear increase in the suspended dust in Nasirya and Basrah station , and more in Omara station. It has been use BANMAN - MONTETH depended by ( W.F.A.O) which depended on active rain and Evaporation, a clear change has occurred and all the station suffer from permanent deficit and time and special variation in the study area , and in spite of the permanent deficit , but, there was time and space variation , in Nasriya station trends towards decreased in Evaporation , while Basrah station towards increasing , coincidence with temperature increase and wind speed , as for Omara, which differed from the two station and there existed time variance at months levels and all the stations suffer from permanent deficit in climate water balance. The study shows the presence of development in Marshes refreshment process and the water in come from Tigris and The Euphrates has its effect on the inundated area and 1973 was depended as basic year for the required area which 8350 Km2, dried to reach less than 1000 Km 2, between(1990 - 2002) and re - back inundation an area of 3536 Km2 at the end 2013, of inundation (64%) of the qualified inundation area amounted 5560Km2 , and excluded an area 2790Km2, for the difficulty of restoring it to utilize it for agriculture and oil wells or disagreement of the its population to inundate them, we could say that , the climate change indicators in climate elements, reflected negatively on processes of refreshment marshes, where the effect appeared clearly on the study area.
