Urban river pollution causes serious problems to the environment, sedimentation of shore, human health, and water scarcity. This study compared the sediments at the weir level of rivers in the city of Bukavu, Lake Kivu basin in the Democratic Republic of Congo between 2003 and 2021. To do this, Google earth images from 2003 and 2021 were used and data was processed by the cartographic software ArcGIS 10.7.1. The rivers are at the base of the displacements of the sediments in Lake Kivu and in 2021 on these sediments of Lake Kivu are built homes anarchically. The invasion of the shore of the lake is not only the work of the rivers, in certain places the population of Bukavu brings piles of earth which it pours into the lake and thereafter it erects houses on these lands which it considers to be parcels. The authorities must protect this heritage which also contains a large quantity of methane gas which constitutes not only a threat but also and above all an opportunity for wealth for the country.
