ENGLISH ABSTRACT: Natural slopes and man-made cuttings in weathered, highly jointed or fractured rock with unfavourable bedding planes can result in the release of rock blocks either from above these slopes and cuttings ...

ENGLISH ABSTRACT: South African municipalities are under pressure to improve the current state of the water andwastewater service delivery industry. Knowing that there exists a need for improvement within the municipal water ...

The climate of the world varies from one decade to another, and a changing climate is natural and expected. However there is a well-founded concern that the unprecedented human industrial development activities of the ...

ENGLISH ABSTRACT: The various consequences of climate change pose a significant threat to developments near the coast. These threats include saltwater intrusion, coastal erosion and flooding. In the coastal context, the ...

ENGLISH ABSTRACT: Sea-level rise due to climate change results in deeper water next to existing coastal structures, which in turn enables higher waves to reach these structures. Wave overtopping occurs when wave action ...

ENGLISH ABSTRACT: A critical evaluation of provisions for imposed loads in the South African Loading Code for design of structures, SABS 0160-1989 (SABS), by comparison with other codes was performed earlier. The ...

ENGLISH ABSTRACT: This study sets out to describe the incipient motion process in cobble/boulder bed rivers in terms of the unit applied power approach. This objective has been met through the collection of data on stone ...

ENGLISH ABSTRACT: Riprap is commonly used as an erosion protection measure around the world. In some cases, for example when constructing bed arrestors, riprap has to be designed to be stable on steep slopes. The literature ...

ENGLISH ABSTRACT: Hybrid concrete construction (HCC) is a construction technique that makes use of both in-situ and pre-fabricated concrete products by making optimum use of the advantages of both these methods in the ...

ENGLISH ABSTRACT: General objective of the study This thesis aims to evaluate the hydraulics of an inflatable weir in its fully inflated position to the almost fully deflated position using different diameter circular ...

ENGLISH ABSTRACT: Plastic shrinkage cracking (PSC) is a well-known form of cracking in concrete at early ages and causes major concerns with regard to durability and aesthetical appearance of concrete structures. PSC is ...

ENGLISH ABSTRACT: The Western Cape has been subject to extreme rainfall storms in the last decade, which has been responsible for millions of Rands worth of damage to public infrastructure and human settlements. Current ...

ENGLISH ABSTRACT: The aim of this research is to investigate the potential use of coarse recycled concrete aggregate (RCA) as a material in structural concrete. The lack of knowledge and specifications in South Africa are ...

ENGLISH ABSTRACT: This research study investigates the influence of specimen geometry and grading curve, on the performance of a typical South African unbound granular material. The experimental design incorporates three ...

ENGLISH ABSTRACT: Surface seals are widely used in South Africa. There are a number of reasons which include affordability, versatility and durability. There are, however, in some cases problems with stone loss that can ...

ENGLISH ABSTRACT: The hypothesis postulated in this research, namely that the effectiveness of natural and constructed buffer dune systems can be assessed by a set of indicators that defines the integrity of the dune ...

ENGLISH ABSTRACT: The Square Kilometre Array (SKA) is a global project to build the world’s largest telescope that stretches over at least 3000 km. There is a number of factors that need to be considered during the planning ...

Bonded overlays are increasingly used in concrete and reinforced concrete repair and rehabilitation applications, despite the high probability of interfacial debonding. Reasons for such failures include inefficient substrate ...

ENGLISH ABSTRACT: The investigation of the interrelationship of the fluvial morphology and the salinity of the Great Fish River Estuary was performed by the combination of a two-dimensional morphological model and a one ...

In the inverse finite element method (iFEM), given a finite element model of a structure and imperfect displacement measurements, the external loads acting on the structure can be assessed. The basic idea behind iFEM is ...
