Projects from 2010 to 2017
Ruo River Flood study, Malawi (2017/18)
Hydrodynamic modelling of the 2015 flood flow patterns and sediment transport with the breaching of the railway line. Simulations to design a new berm to force the Ruo River back to its original course prior to 2015 flood, on the border between Malawi and Mozambique.
Reservoir sedimentation study of the proposed 120 m high Pavua Dam on the Pungwe River, Mozambique (2016 to 2017)
Sediment yield modelling (SHETRAN) considering future climate change and land use change impacts; reservoir sedimentation modelling considering current and future land use & climate change scenarios; mitigation measures to limit the sedimentation.
Thukela River at Middeldrift pumpstation upgrade study, South Africa (2017)
Doubling of the river abstraction works pump capacity to about 3 m3/s, as part of the water transfer scheme between the Thukela River and Goedertrouw Dam. Field work, hydrodynamic modelling of flow and sediment dynamics, and hydraulic design of the new upgrade abstraction works and desilting works.
Metolong Dam in Lesotho (2016)
The Metolong dam water supply programme forms part of the Lesotho Lowlands water project, aimed at improving water supply for domestic water consumption and for local industry, which was hampered by an acute water shortage in the Mountain Kingdom. According to the World Bank, the new dam supplies water to two-thirds of Lesotho’s two-million population. The 83 m high dam in Lesotho was completed in 2016. The Metolong Dam is situated 30 km east of Maseru and features a 280 m long crest, with a 75 m spillway. It is a roller-compacted concrete gravity dam. The spillway design of the dam was optimized by Prof Gerrit Basson and he also investigated the future reservoir sedimentation of the reservoir.
Tsomo River abstraction works, South Africa (2010; construction completed 2020)
River hydraulics and fluvial morphology to design the river abstraction works and weir. Client: Maluti GSM and DWS.
