Conference Paper
Full-text available
High sedimentation rates at Thwake Dam poses a threat to the dam's design life span. The SHETRAN hydrological model was utilised to estimate the long-term sediment loads. Three sets of scenarios were considered; observed rainfall + the European Space Agency (ESA) land-use changes for (a) the year 2000, for (b) the year 2016 and for (c) the predicte...

Water is at the core of sustainable development and is critical for socio-economic development. Inconsistent rainfall in the recent past has affected water security for basic consumption as well as economic use within the Limpopo province. The Musina-Makhado Special Development Zone (MMSEZ) a State Owned Company (SOC) has been collaborating with va...

The effect of varying vortex settling basin (VSB) outlet configurations on the removal of sediment particles >75 μm was computationally investigated using ANSYS Fluent's Euler-Lagrange approach, which incorporated supervised optimization and was validated by physical modeling. A rectangular centroidal outlet was established with a low outlet weir a...
Article
Diverted sediment causes a wide range of problems at small diversion works. The difference in water levels between low flows and floods, low investment capital and presence of cohesive sediment and fine non-cohesive sediment coupled with a requirement for a high level of supply assurance makes the design of such hydraulic structures complex. Vortex...

Executive Summary More than a decade ago, a SA Water Research Commission (WRC) study was completed by Stellenbosch University and guidelines were generated for the hydraulic design of river abstraction works: "Considerations for the Design of River Abstraction Works in South Africa" (Basson, 2006). The guidelines have been used in the designs of ma...
Conference Paper
Full-text available
A vortex settling basin (VSB) offers a promising alternative to conventional sediment settling structures, such as sand traps, for the removal of fine non-cohesive sediment for potable water use at small river abstraction works of less than 100 l/s pump capacity (7.2 Ml/d at 20 h/d). The hydraulic design of a suitable VSB was carried out by numeric...
Conference Paper
Full-text available
In order to develop an integrated water resources development plan, accurate prediction of sediment yields in a basin is important. The study area is one of the four major sub-basins in the Eastern Nile Portion of the Nile basin. It is located in the southernmost portion of the Eastern Nile Basin contributing about 26 billion m 3 of water every yea...
