Abstract:

Abstract. Rivers in the Kruger National Park, eastern South Africa, are characterised by bedrock-influenced "macrochannels" containing variable alluvial thicknesses and riparian vegetation assemblages. Evidence from the Sabie and Olifants rivers suggests that flows up to moderate floods (<3500 m3 s−1) tend to result in net alluviation, with sediments gradually covering the underlying bedrock. More extreme floods strip alluvium and erode bedrock, effectively exerting the primary control over long-term river morphologic development. On the Olifants River, post-flood aerial LIDAR imagery revea

Abstract:

Socioeconomic development objectives are integral to the integrated river basin management initiatives in several river basins around the world, including the Olifants River Basin of South Africa. All viable strategic water management alternatives are expected to contribute towards such, usually predefined, socioeconomic objectives in addition to other hydrological and ecological objectives. An assessment of the relative merits of different alternatives becomes imperative to trace the respective contributions of the alternatives to such objectives and thus to identify the best-bet and most agr

Abstract:

The tributaries of the Olifants River draining the Cedarberg Mountains in the Western Cape are well known for their diverse fauna of endemic freshwater fish. Aquatic ecosystems in the region have also been identified as being particularly important in terms of ecosystem conservation. Recent surveys of aquatic macroinvertebrates have indicated that the region is rich in Trichoptera, with a number of regional endemic species, some of which are not recognizable as known described species. The distribution of certain species appears to be confined to either the arid east-flowing tributaries of the

Abstract:

The Olifants River Bridge B3611 carries the N11 over the Olifants River, just North of the Loskop Dam. This structure was originally built in 1979 and was recently widened as part of the South African Roads Agency Limited (SANRAL)’s upgrade to the N11. At the time of design, very little was known about the bridge as no ‘As Built' drawings were available. Due to the remote locality of the structure, exploratory investigations were reserved until the construction phase. The final design solution was therefore amended during the construction phase in order to account for the reinforcement found w

Abstract:

Exploratory modelling of the impact of gold mining on groundwater in a strategic water area of South Africa was undertaken. A systems dynamics (SD) model was developed to simulate the impact of gold mining on water quality, focusing on groundwater contamination risk, within the context of competing developmental priorities around water resource development and the socio-economic gains from gold mining. The model also identified interventions to minimise the impacts by the year 2040. The study area was the Blyde River Catchment (BRC), which is part of the Olifants Water Management Area in South

AbstractPotamonautid river crabs were collected from four sites along the Olifants River in the Western Cape, South Africa in order to determine morphological and genetic differentiation among these populations. Two distinct forms were identified, and fixed allele differences at some allozyme loci between sympatric populations of the two forms confirmed that they were reproductively isolated. It was concluded that these forms represent two species, one of which was previously unknown, and is described in this paper as Potamonautes parvispina sp. nov.

The following five perennial rivers were selected: the Crocodile, the Letaba, the Olifants, the Sabie, and the Sand.

Invasive alien plants have a negative impact on ecosystem goods and services derived from ecosystems. Consequently, the aggressive spread of invasive alien plants (IAPs) in the river catchments of South Africa is a major threat to, inter alia, water security. The Olifants River catchment is one such a catchment that is under pressure because of the high demand for water from mainly industrial sources and unsustainable land-use, which includes IAPs. This study considered the cost-effectiveness of clearing IAPs and compared these with the cost of a recently constructed dam. The methods used for
