HYDROLOGICAL STUDY OF NACALA DAM IN MOZAMBIQUE

JG Afrika | Hydrological study of Nacala Dam in Mozambique
Completed construction of new spillway at Nacala Dam.

JG Afrika (Pty) Ltd were involved in the feasibility study and detailed design to rehabilitate and raise the Nacala Dam wall in Mozambique.

A detailed rainfall patching process was deployed due to limited rainfall records and Spreadsheet-based methods were developed specially for the project.

Stream flows from a similar catchment were used to determine the system yields of the dam storage, while further hydrological input included determining the environmental-flow requirements.
