This study aims to detect the changes that occurred in Euphrates River (channel and banks) in Habbaniyah - Fallujah area due to the effect of the Al-Tharthar - Euphrates artificial channel, which is connected to it from the left side of the river channel. Then detect the risks and identify areas threatened by that shifting. Also field measurements to the reflectivity of bank deposits and the possibility of determining the age of the banks based on the difference in reflectivity of the newly deposited or the original old ones, it's an additional factor in determining the eroded areas of the banks (most negative signs) and those that are recently deposited caused narrowing in channel width. Assess the suitability of both Landsat series and Sentinel-2 a satellite for estimating and mapping the stability of river channel with any change happened over the years. Rivers generally change according to the nature of the region and the strength of the influences. Reflectivity sections were measured for four selected sites of the Euphrates River before and after the connection of the Tharthar with the Euphrates River and during the connection of the Tharthar Channel with the Euphrates River and the channel itself to reveal the possibility of its significant impact on the river. The measurements were made in two seasons, November (end of the dry season) and April (end of the rainy season). The result showed that there is a direct relationship between changes in reflectivity and river activities. At the same time as the measurements, another type was measured, which is speed and depths, which are an indicator of change in the past and the possibility of impact in the future. This work was supported by a series of aerial images via satellites (1972-2024), as well as calculating the sinuosity factor. The result revealed through field and satellite images that the river’s activity and stability appear.
