Evolution of Sedimentation in a Headrace Canal for Hydroelectric Production Case of the Shongo Basin of the Inga Complex from February 2020 to May 2021 (Kongo Central Province/DR Congo)

The headrace of the Inga hydropower complex is experiencing siltation problems, reducing exploitable draft and limiting production capacity two main plants during low water period. During 2019 period, several sediment slumps occurred in Shongo basin, disrupting hydroelectric power generated by 1 & 2 plant, resulting massive load shedding supply to downstream customers. cardinal aim this study determine quantities sediments deposited those eroded, order know evolution sedimentation basin from February 2020 May 2021. results obtained show that running index turbines alternators groups determinant influences process basin. cleaning terms spatial distribution 2021 plausible.
