M.A. / The management of the stormwater flow and other related environmental issues within the catchment of the Fourways Spruit have been investigated against the background of accepted management practices in other countries throughout the world. The local conditions and aspects that had an influence on the stormwater flow patterns and an impact on the environment along the Fourways Spruit have been taken into account in the study. The research problem has been divided into three main categories, namely the stormwater flow in the Fourways Spruit and the management of it, the related urban environmental problems, and the social problems related to the urban development and stormwater flow in the Spruit. Each category has been divided further into sub-categories in order to obtain indepth information on every aspect and to conduct a proper evaluation of the main problem. The existing situation as well as the problems that can be expected in the catchment was analysed in order to confirm the exact nature of the problem. Apart from the general problems associated with urbanisation and an increase in stormwater flow patterns, a number of specific problems were identified for each category. It became evident that the increase in the stormwater flow patterns in the catchment area of the Fourways Spruit was not managed in terms of accepted stormwater management practices. Certain sections of the streambed has degraded to such an extent as a result of the erosion that took place over years, that serious rehabilitation and maintenance work will be necessary in an attempt to restore the functionality of the Spruit and also to manage the stormwater flow to a certain extent. In addition, a number of new attenuation structures and measures will have to be introduced to manage the anticipated stormwater flow volumes in the future. The degrading of the stream and the natural vegetated areas along it has resulted in an accumulation of problems, also affecting the environmental and social aspects. Natural floral and faunal habitats were destroyed as a result of the erosion of the streambed and the removal of natural vegetation by replacing it with cut lawns and landscaped gardens. The large commercial component in the catchment further contributed to the environmental and aesthetic problems due to the abnormally large areas of paved surfaces resulting in the inflow of high volumes of polluted water and litter into the Fourways Spruit. The Fourways Spruit has the qualities and capabilities to function as a drainage system where the stormwater flow can be attenuated to acceptable levels. The areas along the Spruit can also function as an open space system for formal and informal recreational purposes. Suitable areas should be demarcated where the natural and safe habitats can be preserved or restored to improve the abundance and diversity of bird and animal life. A number of proposals and recommendations have been made which will improve the current condition of the Fourways Spruit. In essence, it is recommended that all the various plans, proposals, and initiatives be integrated into one workable document, namely, a Stormwater Management Plan. The recommendations and proposals regarding the necessary rehabilitation and maintenance to the streambed will improve the physical condition of the Fourways Spruit and will have in immediate positive visual impact. As the majority of problems that have been identified can be related to environmental management, the impact of the recommendations on the surrounding environment and the effectiveness of the proposed management structures and control measures will only be visible over a longer term. Should a Stormwater Management Plan, as recommended, not be prepared and implemented, it will have a serious negative impact on the Fourways Spruit, the surrounding environment, and the community living in the area.

The water quality of stormwater runoff from various road surfaces in Durban, KwaZulu- Natal was characterised by monitoring programmes established at four study areas. The investigation focussed on obtaining representative stormwater samples in order to quantitatively identify pollutant constituents transported within stormwater runoff from road surfaces during rainfall events. Stormwater runoff is a leading cause of degradation in the water quality of receiving water bodies. A review of sampling methods and equipment, informed by the objectives and resources of this investigation, resulted in the development of a stormwater runoff sampler. An economical flow weighted composite sampler was designed, developed and tested. The sampler produces one representative composite event mean concentration sample. Controlled laboratory experiments, computer simulations and field tests were conducted in order to test and calibrate the sampler. The product of the event mean concentration and total runoff volume estimated provide an estimation of the total pollutant loading from a particular drainage area. Twenty stormwater runoff event mean concentration (EMC) and atmospheric deposition samples were collected over an eighteen month period. The characterisation of stormwater runoff for this investigation included heavy metals, oxygen demanding substances, sediments and physico-chemical analysis for pH, conductivity and water hardness. Chemical analysis indicates that the pollutant levels of constituents sometimes exceeded EMCs reported internationally. The majority of contaminant EMCs exceeded the South African wastewater discharge general and special limits. The results also indicate a 60% reduction in lead (Pb) levels since the introduction of lead-free fuel in South Africa in January 2006. The findings from this investigation will provide decision-makers with an improved local data base for estimating the impacts of road transportation systems on water quality. A comparison between the four study areas also provides guidance concerning the variability of stormwater quality from different road surfaces and usage patterns. / Thesis (M.Sc.Eng.)-University of KwaZulu-Natal, 2006.

Two catchments were investigated to determine whether the "first flush" effect was likely to occur in metropolitican Adelaide, South Australia. The residential catchments chosen were located in at Halsey Road, Henly Beach South and Riverway, Fulham Gardens; their areas were 155 ha and 18 ha respectively. / Thesis (MEng(CivilEngineering))--University of South Australia, 2001.
