(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The main objective of this thesis was to determine the critical MN that defines the incipient failure conditions of angular riprap dumped on wide and steep trapezoidal channels. A total of 32 physical ... -
Aspects of self-cementation when applied in roads
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Worldwide, the growing volumes of traffic have led to the increase in an expanding infrastructure that must be continually maintained. Congruent with these developments are undesirable environmental c ... -
South African novice drivers: exploring hazard perception development during the learner driver training phase
(Stellenbosch : Stellenbosch University, 2019-04)Introduction Novice drivers, worldwide, have an increased risk of being in a fatal crash. Despite reliable crash data, indications are that South African novice drivers are no exception and that novice drivers form part ... -
Modelling outdoor water use of homes in gated communities
(Stellenbosch : Stellenbosch University, 2019-02)ENGLISH ABSTRACT: Gated communities are commonly referred to as residential estates, or common interest housing developments. The homes in a particular gated community are often closed off to the general public by means ... -
Investigation into flow-induced vibrations of piano key weirs
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: This thesis considers the transient behaviour of piano key weirs (PKW) from a hydrodynamic and structural perspective. Their geometry makes them very rigid structures, however, there are thinner components ... -
Modelling breakthrough curves and investigating the impact of models and numerical properties on parameter estimation
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The research investigated and applied several Eulerian numerical methods of the advection-dispersion model (AD-Model) for the analysis of concentration-time curves, also known as breakthrough curves (BTCs), ... -
