The applicability of C&D waste material in South Africa road construction.
(2018)In contrast to developed countries, South Africa is starting to adopt the practice of using recycled rubble from civil engineering demolition works in road construction. This change is due to environmental considerations, ... -
Towards a zero waste South Africa : a case study on post-consumer solid waste management in rural and urban areas.
(2009)Through the National Environmental Management Act (No. 107 of 1998), the South African Department of Environmental Affairs and Tourism (DEAT) introduced the concept of the Waste Hierarchy (Reduce - Reuse - Recover - Dispose) ... -
Traffic circles in South Africa : traffic performance and driver behaviour.
(1997)This thesis presents the results of an investigation into traffic operations and driver behaviour at traffic circles under South African conditions. The scarcity of local traffic circles necessitated the development of ... -
Turbulent mixing and dispersion in environmental flows.
(2002)Stably stratified flows are common in the environment such as in the atmospheric· boundary layer, the oceans, lakes and estuaries. Understanding mixing and dispersion in these flows is of fundamental importance in ... -
Ultimate load and deflection behaviour of cellular beams.
(2001)Cellular beams were developed in 1987 and are an adaptation of castellated beams having many of the same advantages and disadvantages. There are no published results of tests on cellular beams and there is only one ... -
Understanding flow structure in a groyne field.
(2018)Groyne structures are widely used all over the world for the purposes of controlling longshore currents and slowing down the rate of sediment transport along coast lines. The limited previous studies in this area have led ... -
A universal method for assessing intrinsic expansiveness of soils.
(2004)Many of the attempts made over the past six decades to find a universal system for assessing expansiveness of soils using soil index data have failed to follow the basic principles of soil mechanics. By overcoming most ... -
Urban poverty reduction through municipal solid waste management (MSWM) : a case study of Maseru and Maputsoe in Lesotho.
(2002)The study was designed to generate data and information necessary for designing an appropriate sustainable solid waste management system, and examining the socio-economic benefits of urban municipal so lid waste management ... -
The use of commercial garden refuse at different degrees of maturity as an organic carbon source to bio-denitrify treated MSW landfill leachate.
(2014)Abstract available in PDF file. -
Use of multi-criteria decision analysis integrated with GIS and air pollution model inputs for schools site selection.
(2019)Schools site selection is an essential process which needs knowledge of different fields. The process involves scientific justification, judgment and a finding of suitable land, which consider financial, social, ecological ... -
The use of small scale hydroelectric power in South Africa, hydro and economic potential for rural electrification.
(2012)Small hydro generation refers to generating capacity of less than 10 MW with the most common being Run-of-River. In South Africa, the level of rural electrification is approximately 50 percent with most of the energy ... -
Wind driven waves and re-suspension dynamics in shallow lakes : St. Lucia, South Africa.
(2014)Abstract available in PDF file. -
Wind induced sediment re-suspension in a shallow lake.
(2011)Wind induced turbidity within shallow lakes can greatly affect the biological functioning of a system in either a positive or negative manner. This research aims to understand and model the physical processes that cause ...
