Summary

Description
English: The Grand Ethiopian Renaissance Dam, with a total volume of 10 million m3, is the largest dam in Africa. It is located 500 km northwest of Addis Ababa (Ethiopia), and is fed by the Nile river. On 21 July 2020, the maximum capacity of the dam reservoir was reached for the first time since its completion. This image, obtained by combining multiple Copernicus Sentinel-1 satellite images from 27 June, 9 and 21 July, shows the stages of the reservoir‘s growth. The surface of the reservoir between June 27 and July 9 is shown in red tones, the yellow tones depict the water storage extent between 9 and 21 July. Data obtained by the radar on board Copernicus Sentinel-1 satellites allow us to monitor, with very high precision, the surface of reservoirs and to derive the volume of water in storage, as well as to monitor the structural stability of dams.
