Abstract The importance of identifying the surface drainage patterns of virtual valleys through the DEM files in the study area, which is an important agricultural area in Diwaniyah governorate, gives a clear picture of the surface water collecting areas which are groundwater recharge areas. They also indicate the high humidity areas in the soil as low areas This is especially important in agriculture, especially since the region is characterized by a dry climate. This affects the increase in the salt content of the wet areas in the summer due to the evaporation process or the increasing humidity in the winter due to the accumulation of rain water to the extent that the plants cannot tolerate it. This is also important in the quantity and quantities of irrigation. Moreover, knowledge of the flow trends is important in the implementation of irrigation and drainage projects for this area where agricultural activity is an important activity. Most of the trends of the flow of study area towards the south - east and south, which should be taken into account when establishing irrigation and drainage projects the predominance of the tree pattern of the default discharge in the study area due to the sedimentary geological reality of the region.
