摘要：Global warming is hitting all parts of theworld for the last fifty years due to Global Climate Change and it is expectedto continue in the future in an increasing trend unless the present mode of CO2emission is limited or reversed. This is manifested in the rising temperatureover land and the changes induced in the general weather circulation patternsover land and oceans. The Tigris River catchment as most of other parts in theworld is suffering from increased temperatures and reduced precipitationcontributing to reduced water resources elements all over it and reduction ofthe river stream flow itself. Studies using the soil and water assessment toolSWAT were performed on the five Tigris River tributaries basins in Iraq inorder to assess these impacts. This paper summarizes the results of thosestudies, the characteristics of each of the five basins, and illustrates theapplication of SWAT as a tool for future predictions. Moreover, it explains inmore details the work done on one of the basins as an example, summarizes theresults of the five studies and then analyzes these results and discusses theexpected future outcomes. The final conclusion which can be drawn is thatsevere shortage in all water resources elements will occur over the five basinsand the Tigris River stream flow will suffer a considerable decline. Thissituation demands that policy makers in Iraq should take steps immediately toimprove water and soil management practices to try and reduce as much aspossible the expected damage that will hit all water using sectors.Keywords: Climate Change, Global warming,CO2 emission, SWAT model.
