Participants of the PhD exchange (TUKS, UCT, CUT, UJ, SUN with Durham) will be presenting their work.
Regulations for water conservation and pollution control in South Africa have evolved to reflect changes in knowledge and good practice around the world in the 21st Century. The workshop will provide an introduction to barrier systems used in many landfill and mining applications (with an emphasis on landfills, as well as dams, lagoons, tailings and heap leach applications). The course does not require prior knowledge of barrier systems or geosynthetics as it will cover from basic of barrier systems and components such as hydraulic containment and leachate collection systems, to the latest knowledge about leakage (holes, direct contact and wrinkles) and how it can be minimized as well as the factors affecting the service-life of geosynthetics and especially geomembranes in barrier systems. The course will cover how design, construction and operations can all affect the performance of a barrier system and the consequent leakage, with particular emphasis on the need to take the effects of exposure conditions such as temperature, tensile strain, and nature of leachate into consideration. Several intervention by the South African Regulator will focus on current practice in South Africa highlighting the importance of drainage and the consequences of relying on indicator rather than performance specifications. Some common perceptions, misconceptions and optimistic, but incorrect thinking, that can result in failure of the system will be presented and discussed. It is presented in a form that will provide value to engineers who wants to get acquainted to barriers system design as well as experienced engineers and contractors in the field.

1. Barrier system components & transport mechanisms – Kerry Rowe
2. Natural clay and compacted clay liners (CCLs) – Kerry Rowe

About the Course
In this short course, the general notions of sustainability and its application to geotechnical engineering will be covered. The sustainability assessment methods applicable to geotechnical engineering will also be included. A focus of the course will be on the latest developments related to sustainability in geotechnical engineering. The topics that will be covered fall under three broad areas:
(1) philosophies and concepts of sustainability and resilience,
(2) applications of sustainability principles in geotechnical practice, and
(3) sustainability assessment tools in geotechnical engineering.
Specific topics that will be covered include principles and philosophies of sustainability including a historical overview; connection between sustainability and engineering, civil engineering, and geotechnical engineering; specific examples of sustainable practice in geotechnical engineering, e.g., utilization of recycled materials, use of alternate materials and construction methods to reduce carbon foot print, geotechnics for renewable energy, reuse of foundations, etc.; and sustainability assessment tools. Among the sustainability assessment tools, emphasis will be given on life cycle assessment and environmental impact assessment, and examples will be solved to show their use in geotechnical engineering practice.
