Invasive alien plants and water resources in South Africa : current understanding, predictive ability and research challenges
(Academy of Science for South Africa, 2004)Predictions that invasive alien plants would use significant amounts of water were a major factor in the establishment of South Africa's Working for Water programme, which aims to protect water resources by clearing these ... -
Investigation into increasing short-duration rainfall intensities in South Africa
(Water Research Commission, 2015-04)Extreme storms in South Africa and specifically in the Western Cape have been responsible for widespread destruction to property and infrastructure, even leading to displacement and death. The occurrences of these storms ... -
An investigation into the evidence of seasonal rainfall pattern shifts in the Western Cape, South Africa
(South African Institution of Civil Engineering, 2017-12)ENGLISH ABSTRACT: Climate change is a highly contentious topic in the modern world. There is much evidence to indicate that climatic shifts and extreme weather anomalies are taking place globally, in some places more ... -
The management of constructability knowledge in the building industry through lessons learnt programme
(South African Institution of Civil Engineering, 2014-04)In the 1980s the term "constructability" evolved in the USA. The proponents of this concept believe that constructability, which embraces both design and management functions, is comprehensive in facilitating construction ... -
Perceptions of professional practitioners and property developers relating to the costs of green buildings in South Africa
(South African Institution of Civil Engineering, 2015-12)Sustainable design practices are a key component in ensuring that the building and civil infrastructure industry does not damage our natural environment. Green buildings – and allied initiatives in other sectors of the ... -
Planning for desalination in the context of the Western Cape water supply system
(South African Institution of Civil Engineering, 2017-03)ENGLISH ABSTRACT: As water demands continue to grow, South Africa is starting to consider seawater desalination as a potential future supply source, and it is currently being investigated at a feasibility level in a number ... -
Potable water use of residential consumers in the Cape Town metropolitan area with access to groundwater as a supplementary household water source
(South African Water Research Commission, 2016-01)The potable water use recorded by 3 579 residential consumer water meters in Cape Town, South Africa, was analysed as part of this research. The focus was on elected residential properties in serviced areas, with additional ... -
Reliability assessment of the South African wind load design formulation
(South African Institution of Civil Engineering, 2018-09)ENGLISH ABSTRACT: The representation of the strong wind climate and the reliability calibration of wind loading are the main components of the provisions for local conditions in the South African wind load standard. The ... -
Residential water information management
(AOSIS OpenJournals, 2008-12)The hitherto undefined term 'water information management' (WIM) as it relates to residential water use is defined in this article as follows: 'To better manage the information pertaining to how and when water is used at ... -
Resistance model uncertainty factors for ultimate limit state design of pile foundations
(South African Institution of Civil Engineering, 2014-08)ENGLISH ABSTRACT: The current limit state design procedure for pile foundations presented in geotechnical codes (e.g. SANS 10160-5, EN 1997-1) stipulates that, when the pile capacity is determined using an analytical ... -

(South African Institution of Civil Engineering, 2017-06)ENGLISH ABSTRACT: This paper presents the research on the revision of the regional probabilistic method (Rooseboom et al 1992) for the prediction of catchment sediment yields in South Africa. The determination of sediment ... -
Rocking shear wall foundations in regions of moderate seismicity
(South African Institution of Civil Engineering, 2013-10)ENGLISH ABSTRACT: This paper presents a study which investigates the feasibility of a concept to reduce the size of shear wall foundations for earthquake forces in regions of moderate seismicity. The approach is to allow ... -
Seismic evaluation of the northbound N1/R300 bridge interchange
(South African Institution of Civil Engineering, 2016)The design of the Stellenberg Interchange was finalised in 1982, with construction completed in 1986. The bridge was designed using a code of practice which did not include any requirements for seismic excitation. This ... -
Sewer network design : heuristic algorithm for hydraulic optimisation
(South African Institution of Civil Engineering, 2017-09)ENGLISH ABSTRACT: For a given sewer network layout and choice of pipe material, the total installed cost of the network is determined mainly by the pipe diameters and slopes. Hydraulic design optimisation is the task of ... -
Sewer network design layout optimisation using ant colony algorithms
(South African Institution of Civil Engineering, 2018)The optimal design of sewer networks typically comprises two sub-problems. The first is to determine an optimal layout of the network elements, and the second to optimally design the network components. In this article the ... -
Stormwater pond efficiency determinations with the effluent probability method : the use of mass versus concentration parameters
(South African Institution of Civil Engineering, 2016)Use of the concentration parameter has in the past generally been favoured in stormwater structure efficiency determinations, and specifically with use of the Effluent Probability Method. However, efficiency is by definition ...
