Scour of unlined dam spillways
(Stellenbosch : University of Stellenbosch, 2010-12)
ENGLISH ABSTRACT: The scour process of unlined spillways is an important research topic of value in engineering practice.
In South Africa numerous unlined spillway dams have experienced severe erosion. This led, in ...
A two-dimensional numerical model for the investigation of the effects of dams on the Zambezi River Delta
(Stellenbosch : Stellenbosch University, 2014-04)
ENGLISH ABSTRACT: The Zambezi River is the largest east-draining river in Africa. It captures runoff from 8
different countries before draining into the Indian Ocean in Mozambique through the
Zambezi Delta which is ...
Transverse transport of suspended sediment across the main channel – floodplain shear boundary
(Stellenbosch : University of Stellenbosch, 2006-12)
The floodplain of a river forms a close relationship with the stream that created it. Not only does
the river influence the characteristics of the floodplain, the floodplain can also very easily
influence its river, as ...
Bend diversion to minimise sediment intake
(Stellenbosch : University of Stellenbosch, 2004-12)
ENGLISH ABSTRACT: The primary aim of the research was to determine the optimum diversion location in a
curved channel to minimise the abstraction of sediment. The secondary aim was to
determine the optimum diversion angle ...
The cross-shore distribution of grain size in the longshore transport zone
(Stellenbosch : University of Stellenbosch, 2009-12)
ENGLISH ABSTRACT: Calculation of longshore sediment transport rates is a typical part of coastal engineering work.
One of the important inputs to such calculations is the sediment grain size. A single,
representative ...
Evaluation of incipient motion criteria for rock in Reno mattresses and rip rap
(Stellenbosch : University of Stellenbosch, 2005-12)
There has always been some debate in the past about the most effective and economical type of revetment to be used to combat or prevent erosion in rivers and channels. Some of the most common materials used for these ...
2D Modelling of turbulant transport of cohesive sediments in shallow reservoirs
(Stellenbosch : University of Stellenbosch, 2006-12)
Modelling of the transport of fine cohesive sediments, as found in most South African
reservoirs, has not been well developed. This is because the transport processes that are
involved are complex and the theories not ...
Conceptual solutions to minimise the effects of cobbles on the sand-bypassing system at the Port of Ngqura
(Stellenbosch : Stellenbosch University, 2016-12)
ENGLISH ABSTRACT: The Port of Ngqura constructed two breakwaters to create safe anchorage for vessels at berth. These coastal structures obstructed the natural movement of sand alongshore. A fixed sand-bypassing system was ...
Beach profile changes subject to wind-driven wave action exemplified by Glencairn Beach, South Africa.
(Stellenbosch : Stellenbosch University, 2022-04)
ENGLISH ABSTRACT: Wind directions influence the wave climate, causing different water levels and higher or lower
waves. Cape Town beaches and especially southern peninsula beaches have two main sea-
sons of sediment ...
