Abstract: The construction of dams for a long time has been considered to manage surface water by societies that are living in arid regions of the world. But today the construction of such structures in most countries has been moving very fast, especially in the last decades in Afghanistan the process of dam construction grown-up dramatically. This study investigates the aspects of Kajaki dam construction via Landsat Satellite images and assesses the impacts of its construction on the vegetation of the areas around the Kajaki in 2000 and 2020. In preliminary processing, 10 vegetation indices including II, IR2, MND, MIRV1, NDVI, PD312, PD322, RAI, SAVI, VINR1 were applied to the Satellite Images. As result, the map of all indicators was extracted for both years i.e., 2000 and 2020, in addition, the parameters such as minimum, average, maximum, and standard deviation of all indicators were calculated to obtain the outcomes. The min of parameters in 2000 was more compared to 2020, which indicates the increase of water in the reservoir rim or water on the upstream side of the dam in 2020, the amount of the other three parameters in 2020 was a significant increase compared to 2000, which indicates an increase in vegetation. The average increase in the indices was more than 27%. This research exposed that the construction of the dam has had a significant impact on increasing agriculture in the region, and it is recommended to use different analyzes using remote sensing on different water resources engineering projects, including dams to get accurate marks.
