| Abstract | ||
| This research has been conducted to study the effects of southern Iraqi marshlands desiccation on the amount of dust fallout on Basrah area, due to the soil physical and chemical degredations and the enhancement of wind erosion and dust storms in there desiccated marshlands. Three wind erosion affected places have been chosen ( Abu-Al-Khasseb , Al-Zubair and Umm Qasser ) as study station . The Results showed that a significant increasing in the amounts of dust fallout after the desiccating process which reached 9.44 , 23.88 and 24.78 gm.m-2 , 36.70 ,53.88 and 52.74gm.m-2 and 171.50 ,489.50 and 432.30 gm.m-2 during the period ( 1974-1989 ) , (1992-1999 ) and (2000-2004) for ( Abu-Al-Khasseb , Zubair and Umm Kasser )stations , respectively . The data also ,showed that the falling dust amount was highest in Umm –Qasser followed by AL- Zubair then Abu - AL -Khasseb through out ( May to August ) in compared to the rest at the months in the studied periods. The Results also showed that the dust texture is simeller to the desiccated marshland soil texture and the numbers of raising dust and dust storms action has been increased after the desiccating process . | ||
