oa Civil Engineering = Siviele Ingenieurswese - River rehabilitation and management : water engineering
Many of South Africa's rivers, especially those flowing through urban areas, have been rendered unstable by ongoing - and often accelerating - development in their catchment areas. Under these conditions, careful rehabilitation and management of river systems is now vital to safeguard lives, property and public assets. In one such intervention, the City of Johannesburg (in conjunction with the implementing agent, the Johannesburg Roads Agency) has commissioned a study on the state of the city's longest river - the Braamfontein Spruit - to establish what needs to be done to improve the natural habitat and surrounding infrastructure. SRK Consulting Africa, who has applied its river engineering expertise to such projects in several water courses over the past decade, is conducting the study. Its practice and methodology is discussed here as a contribution to enhancing knowledge and building a more sustainable society.
