Incipient motion of Armorflex articulating concrete blocks on steep slopes
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Armorflex is an articulating concrete block erosion protection measure that has been used as an alternative to riprap (dumped rock) for many years. Even though extensive research and hydraulic testing ... -
Coupled fully three-dimensional hydro-morphodynamic modelling of bridge pier scour in an alluvial bed
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Local scour at piers has been cited as the main mechanism responsible for the collapse of bridges founded in alluvial beds and yet there is no universally agreed upon design procedure to accurately ... -
Application of real-time traffic adaptive signal control on the R44 arterial, stellenbosch
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: The ever increasing level of traffic congestion experienced within and surrounding the town of Stellenbosch, South Africa, has been one of concern for many years. A large volume of commuter traffic creates ... -
Dimensional stability of lightweight foamed concrete
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Lightweight Foamed Concrete (LWFC) is a variation of low density cellular concrete produced by entraining a system of regular and stable air voids into a mortar base mix. The air void structure in LWFC is ... -
Investigation of a practical application of the maturity method to estimate the early-age strength of concrete
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: This study investigates the accuracy of the Maturity Method to estimate the early-age strength of concrete in a South African context towards the possible optimization of formwork removal of suspended ... -
Development of a deterministic design model for a high-rate algal pond
(South African Water Research Commission, 2018-09-25)ENGLISH ABSTRACT: Inadequate wastewater treatment is a major problem in South Africa. Existing wastewater treatment facilities often lack sufficient skilled labour, resulting in partially treated effluent. Increasing ... -
Analysis of nearshore current patterns using aerial drone measurements at monwabisi
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: This thesis explores the development of a methodology for using quadcopter aerial drones to measure currents in the nearshore zone, along with assessing other possible applications within the marine ... -
Fire Dynamics in Informal Settlements
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: In poor and densely populated countries, the rapid growth in population leads to an increase in landlessness. As a result, the number of people residing in informal settlements is increasing on a daily ... -
Deliberative agent model of a taxi rank
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Minibus-taxi loading facilities known "taxi ranks" in South Africa are designed according to guidelines prescribed by the South African Department of Transport. Currently, it is only possible to observe ... -
The Use of Radar Data to Derive Areal Reduction Factors for South Africa
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: An areal reduction factor (ARF) can be defined as a factor that is applied to point rainfall depths to convert these depths to an average rainfall over a specific catchment area. The concept of ARFs provide ... -
Associations between stormwater retention pond parameters and pollutant (suspended solids and metals) removal efficiencies
(South African Water Research CommissionPublisher's version, 2018)ENGLISH ABSTRACT: Presented in this paper are the results of correlational analyses and logistic regression between metal substances (Cd, Cu, Pb, Zn), as well as suspended solids removal, and physical pond parameters of ... -
Analysis of water use by gated communities in South Africa
(South African Water Research Commission, 2018)ENGLISH ABSTRACT: Gated communities (hereafter GCs) are popular in many countries, including South Africa, because added security and lifestyle improvements are offered relative to homes built on freestanding properties. ... -
The feasibility of using sediments from the Theewaterskloof, Greater Brandvlei and Waterzicht Dams as construction materials
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Between 2014 and 2018, the Western Cape experienced the worst drought that the province has faced since 1904. The drought led to numerous water restrictions being applied by municipalities to regulate ... -
Determination of pullout resistance of galvanized-steel strips within select South African soils based on their free draining potential in mechanically stabilized earth wall backfill conditions
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: Water distribution systems around the world typically comprise a large number of pipelines designed to distribute pressurised water. These pipelines stretch over long distances and vary in diameter, ... -
The prevalence of intermittent water supply in Southern Africa
(Stellenbosch : Stellenbosch University, 2019-12)ENGLISH ABSTRACT: The ability to supply potable water by water utilities in Southern Africa is being threatened by several factors including increased population and urbanisation, increased demand, water scarcity, inconsistent ... -
