Tropical Cyclone-Induced Waves and Storm Surge at four locations along the Southern African East Coast
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: Tropical cyclones are synoptic scale rotating storms that form over oceans with warm water, producing powerful winds and rainfall. The characteristic low pressure of the system and the extreme winds ... -
Three dimensional method for monitoring damage to dolos breakwaters
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: Ports are frequently protected by breakwaters which are designed to withstand harsh environmental conditions over long periods of time. However, in most cases, they gradually or suddenly deteriorate ... -
Seismic performance of steel framed water tower structures
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: From the year 1620 until June, 2008, more than 27000 earthquakes of magnitude ranging from 0.2 to 6.3 have been recorded by the South African National Seismological Database (SANSD). The most affected ... -
Scour of the screed layer underneath a vertical seawall with a rubble mound foundation
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: Scour is here defined as the removal of granular bed material by hydrodynamic forces in the vicinity of coastal structures. It is believed to be one of the most common causes of seawall failure. This ... -
Plastic cracking of concrete and the effect of depth
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: Plastic settlement and shrinkage cracking dominate cracking in the early life of conventional concrete. The mechanisms responsible for these cracking types include differential settlement and restrained ... -
Monwabisi: a hydrodynamic study of the hazardous cell circulation and potential related solutions to a safer bathing facility
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: The objective of this thesis is to investigate the hazardous hydrodynamic circulation pattern at Monwabisi (False Bay, South Africa) and potential solutions to a safer bathing facility, by means of a ... -
Investigation into low cost housing water use patterns and peak factors
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: A need was identified to gain new insight and knowledge regarding the water demand of low cost housing (LCH) developments. More specifically, the primary objective of this study was to improve water demand ... -
The failure of concrete retaining block (CRB) walls
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: Concrete retaining block (CRB) walls have been identified by ECSA (the Engineering Council of South Africa) as a class of structures prone to failure. In South Africa, four major CRB wall failures occurred ... -
An evaluation of the eutrophication prevention potential of high rate Algae Ponds through the development of a deterministic design model
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: Wastewater treatment is a major problem in South Africa. South Africa generally has the wastewater treatment infrastructure in place but often lacks the labour skills to operate these plants efficiently. ... -
Evaluation of storm surge components at Saldanha Bay
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: Extreme sea levels are made up of many different components – the most noteworthy of these include tides, tsunamis, seiches, wave setup, runup and storm surge. The latter is often considered to be the ... -
Effect of the overhang length of a recurve seawall in reducing wave overtopping
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: With the slow but steady rise in sea level, which is due to global warming, the pressure on the coastal zone across the world has greatly increased. In the past coastal developments have frequently ... -
Developing and testing a sprayable overlay of strain hardening cement-based composite for retrofitting of unreinforced load bearing masonry walls
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: In the Western Cape Province (South Africa) a large number of multi-storey buildings, built with unreinforced load bearing masonry (URM) were constructed before seismic resistance became a design standard ... -
Design guidelines for multi-stage outlet structures situated in stormwater attenuation facilities of residential developments in South Africa: physical model investigation
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: Flood attenuation controls are becoming a topic of interest and are more frequently being used within urban areas of South Africa, as local authorities bring into effect stormwater policies and legislation. ... -
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 ... -
Coastal erosion and accretion of beaches - the effect of storm duration, water levels and long waves on selected numerical models
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: Varying water levels, storm duration and long waves all have a significant impact on cross-shore beach profile development. Although it is generally known that these parameters have an impact on beach ... -
Characterisation of high modulus asphalt (EME) mixes, focussing on flexural response and fatigue
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: The road construction industry is faced with the challenge of designing and constructing high performance asphalt materials to meet the ever growing demand of increasing traffic volumes and axle loadings. ... -
BIM as a tool to quantify the impact of change on labour productivity
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: South Africa, when compared to the rest of the world has been relatively slow in implementing BIM technologies. This study aims to nd a new way in which BIM may address problems in construction associated ... -
An appropriate size of toe rock for vertical seawalls
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: The design and construction of an appropriate vertical seawall/breakwater is an important part of an engineering project since the incident and reflective wave forces acting on the vertical seawall cause ... -
Alternative wall-to-slab connection systems in reinforced concrete structures
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: In the construction of multi-storey buildings, the reinforced concrete (RC) core or shear walls normally precede the construction of the RC floors. A system is therefore required to connect the floors ... -
Aeration of Roberts Splitters through an Internal Gallery of a Dam
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: Roberts splitters have effectively been used for more than 75 years to dissipate the flood discharge energy of more than 30 dam spillways in South Africa and abroad. Roberts’ (1943) standard, unaerated ...
