Evaluation of rock types for concrete aggregate suitability for the construction of a gravimeter vault and access road at the Matjiesfontein Geodesy Observatory site near Matjiesfontein, South Africa
(South African Institution of Civil Engineering, 2014-08)Often the use of local rock material for construction purposes is overlooked in engineering, which could reduce costs in terms of procurement and transport, as well as being more environmentally friendly by minimising the ... -
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 ... -
Evaluation of the Catchment Parameter (CAPA) and Midgley and Pitman (MIPI) empirical design flood estimation methods
(Stellenbosch : Stellenbosch University, 2012-12)ENGLISH ABSTRACT: The devastating effects floods have on both social and economic level make effective flood risk management an essential part of rural and urban development. A major part of effective flood risk management ... -
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. ... -
An evaluation of the minimum requirements for the design of rural water supply projects
(Stellenbosch : University of Stellenbosch, 2005-12)In this study, the minimum standards required for the design of rural piped water supply projects as set by the Department of Water Affairs and Forestry (DWAF) are evaluated with respect to capital pipe cost using the ... -
Evaluation of the SDF method using a customised design flood estimation tool
(Stellenbosch : University of Stellenbosch, 2010-12)ENGLISH ABSTRACT: The primary aim of this study was to evaluate, calibrate and verify the SDF run-off coefficients at a quaternary catchment level in the C5 secondary drainage region (SDF basin 9) and other selected SDF ... -
Evaluation of the standard design flood method in selected basins in South Africa
(South African Institution of Civil Engineering, 2012-10)Design flood estimations display relatively wide confidence bands of uncertainty around all estimates of flood magnitude-frequency relationships. Taking cognisance of this, and the fact that most of the available design ... -
Evaluation of the use of flood attenuation controls for the management of urban stormwater impacts in Cape Town, South Africa
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: In the context of rapidly expanding cities, it is imperative that urban planning in South Africa has sufficient guidance regarding stormwater and river corridor management, in order to provide solutions ... -
The experimental determination of structural design parameters for roof covering systems
(Stellenbosch : Stellenbosch University, 2011-12)ENGLISH ABSTRACT: All structures are designed for a particular set of load combinations. For roof structures the critical loading combinations are predominantly wind actions. The accumulative effect of wind actions, by ... -
Experimental determination of the effective elastic constants of thin perforated plates
(Stellenbosch : Stellenbosch University, 1989-03)ENGLISH ABSTRACT: see item for full text -
An experimental investigation into the behaviour of a 5 ton electric overhead travelling crane and its supporting structure
(Stellenbosch : University of Stellenbosch, 2007-03)In structural engineering practice the actions imposed by overhead travelling cranes onto the supporting structure are defined as static forces amplified by dynamic coefficients and applied as pseudo-static forces without ... -
Experimental measurement and numerical modelling of velocity, density and turbulence profiles of a gravity current
(Stellenbosch : Stellenbosch University, 2008-03)The velocity, density and turbulence profiles of a horizontal, saline gravity current were measured experimentally. Stable stratfication damped the turbulence and prevented the gravity current from becoming self-similar. ... -
An expert system for the design of single-storey steel portal frames using the plastic design method
(Stellenbosch : Stellenbosch University, 1994)ENGLISH ABSTRACT: The purpose of this study project is to develop an expert system, PFEXPERT, for the design of single-storey steel portal frames with the plastic design method according to the SABS 0162-1:1993. The ... -
An exploratory study into South African novice driver behaviour
(Stellenbosch : Stellenbosch University, 2014-04)ENGLISH ABSTRACT: Driving is a complex task that requires both the physical ability to drive a vehicle and the cognitive ability to do so safely. The ability to correctly integrate and apply information from the driving ... -
Exploring Driver behaviour under conditions of darkness: shedding light on the night time traffic death toll
(Stellenbosch : Stellenbosch University, 2018-12)ENGLISH ABSTRACT: Road traffic crashes are a global public health concern and the leading cause of deaths and injuries. While it is possible to be involved in a road crash at any given time within the traffic environment, ... -
Extreme wind speeds for the South-West Indian Ocean using synthetic tropical cyclone tracks
(Stellenbosch : Stellenbosch University, 2014-12)ENGLISH ABSTRACT: Tropical cyclones are synoptic scale rotating storms capable of generating intense wind speeds and rainfall with potentially devastating social and economic consequences. In addition to abnormally high ... -
Factors influencing asphalt compactibility and its relation to asphalt rutting performance
(Stellenbosch : University of Stellenbosch, 2004-04)ENGLISH ABSTRACT: This thesis covers the factors affecting compactibility of hot mix asphalt including gradation, filler/binder ratios, binder types, binder content, polymer modification, temperature, volumetric properties ... -
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 ... -
Fatigue performance of seals
(Stellenbosch : Stellenbosch University, 2015-12)ENGLISH ABSTRACT: Thin bituminous surfacings, in particular sprayed seals, are used quite extensively in various countries because they provide a low cost alternative to conventional asphalt. Seals furthermore provide an ... -
Feasibility and geotechnical design of subsurface dams in dry ephemeral rivers for the augmentation of shallow groundwater supply
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: Recent droughts and projected climate changes in South Africa make it an essential priority to augment water availability, particularly in the most vulnerable rural communities. The Molototsi River, a ...
