Projects in 2020

Pongolapoort Dam spillway 3D CFD modelling (2020/21)

CFD modelling of the main spillway and the left bank gated spillway to establish the stage-discharge rating for extreme floods. Client: LTE and DWS.

Limpopo River proposed abstraction works and weir at Musina (2020/21)

Pre-feasibility study of the proposed abstraction works to transfer water to proposed dams on the Sand River for local and regional water supply. Ultimate duty pump discharge of the abstraction works 260 m3/s. Client: Bio Engineering Solutions.

Chobe River proposed abstraction works at Kasane, Botswana (2020/21)

Review of the hydraulic design of a proposed floating river abstraction works for Kasane and probabilistic analysis of flood levels. Client: Bergstan Botswana.

Mzumbe River N2 Road bridge at Hibberdene (2020/21)

Flood hydrology and hydrodynamic modelling of the flood flow patterns and scour patterns at the proposed doubling of the N2 highway with a new dual carriageway bridge. Client: Ingerop and SANRAL.

Caledon River at Caledonspoort proposed river abstraction works and weir (2020)

Flood hydrology, sediment yield, hydrodynamic modelling of the flow patterns and sediment dynamics, hydraulic design of a new weir and abstraction works downstream of the Caledonspoort Bridge. Client: Dihlabeng Local Municipality (Fouriesburg) and Nakeni Projects.

Corumana Dam physical model study, Mozambique (2020)

Hydraulic model study at a scale of 1:60 of the proposed left bank spillway with a PKW and curved supercritical chute. Client: AECOM, Mozambique Government and Word Bank.

Ngwangwane River proposed weir in KZN (2020)

Hydrodynamic modelling of sediment trapping at a proposed weir equipped with automated sediment flushing gates. Client: JG Afrika and local authority.

Sundays River, Nqweba Dam at Graaff-Reinet Reservoir Sedimentation Study (2020)

Investigation of the historical reservoir sedimentation and possible mitigation measures, to increase the firm yield from the dam. Hydrological modelling of catchment sediment yield with future land use and climate change considered. Hydrological modelling of reservoir sedimentation and analysis of mitigation measures such as dredging to obtain a feasible long-term solution. Client: Lyners, Graaff-Reinet Economical Forum and Dr Beyers Naude Local Authority.

Zimbabwe Zambezi River at Deka River abstraction works upgrade study (2020)

Review of the existing river intakes. LLPS and settler which have been in operation for about 40 years for the consideration of upgrade to double in intake discharge required for cooling water at the Hwange Power Plant. Review of alternative intake locations and designs included river hydrodynamic modelling of flow and sediment transport patterns, sediment yield and mass balance calculations in the river, intake, LLPS and settler for current and future increased duty pump discharge capacity scenarios. Client: Bergstan Botswana and ZESA.

Thukela River at Middledrift proposed river abstraction works (2020)

Hydrodynamic modelling of the flood flow patterns and sediment dynamics to determine the best site for a small river abstraction works without a weir. The detail design included the design of a sediment settler above the 100 year floodline. Client: ECA Consulting Engineers and local authority
