Abstract

Iraq's territory overlaps with neighboring countries in rocks, minerals and water, due to the close time period of the structure, which is reflected in the masses rising to them from a distance. The entire region included a large water depression separating two continental masses, one northern called (Eurasia) and the other southern called (Gonodwana), they were separated by a now- defunct sea called (Tethys Ocean). This landscape began to change little by little, coinciding with the alpine movement that occurred in the Miocene era of the third geological time, which is estimated to be between (27-30 million years) old. Where the areas known today on the land of Iraq appeared to us as the highlands, then this was followed by the filling low areas that are known as the floodplain.
The current research is divided into an introduction, three sections, and a conclusion. The first section included the global structure and its impact on the structure of Iraq, while the second section represented the geomorphological process of ancient irrigation canals supported by field evidence. Finally, the third section included the mechanism of formation of the ancient irrigation channels within the rivers of Iraq and enhancing this using technology and satellite visuals. 
The characteristic of vertical drilling appeared at the upstream direction of Iraqi rivers and the deposition load at the mouth of the rivers, this thing is considered as a part of the natural diffusion movement of any river according to Davidian theory, which is reflected in the field in vice versa to the old irrigation channels remained visible on the banks of the rivers, in other meaning they remained visible and were not buried, and this is what called for the rivers to leave their irrigation canals outside the course of the rivers at the source of it, while they were buried and dissolved in the areas of the mouth of the rivers that were running level. One with the surface drainage network to become outside the course of the river, which is usually at its banks likewise. The result of the research indicated that the rivers of Iraq do not complete the beginning of their deltas, which begin near Samarra on the Tigris River and Fallujah on the Euphrates River, and all of this is due to the structure and stratification of the of the lands of Iraq arise.
