Assessing hydrological impacts of tree-based bioenergy feedstock

Author: Gush, Mark B Date: 2010 This chapter provides a methodology for assessing the hydrological impacts of tree-based bioenergy feedstock. Based on experience gained in South Africa, it discusses the tasks required to reach an understanding of the likely water resource ... Read more
An evaluation of how downscaled climate data represents historical precipitation characteristics beyond the means and variances

Author: Kusangaya, S ; Warburton Toucher, ML ; Archer, Emma RM ; Jewitt, GPW Date: Sep 2016 Precipitation is the main driver of the hydrological cycle. For climate change impact analysis, use of downscaled precipitation, amongst other factors, determines accuracy of modelled runoff. Precipitation is, however, considerably more ... Read more
Habitat characteristics, hydrology and anthropogenic pollution as important factors for distribution of biota in the middle Parana River, Argentina

Author: Blettler, MCM ; Oberholster, Paul J ; Madlala, Tebogo E ; Eberle, EG ; Amsler, ML ; De Klerk, Arno R ; Truter, JC ; Marchese, MR ; Latosinski, FG ; Szupiany, R Date: Aug 2018 The regulation of anthropogenic pollution inputs into large rivers is an important aspect of ecological resilience of aquatic systems and river pollution management. The current study examined the relationship between contamination loads, ... Read more
Hydrobiological studies in the catchment of Vaal dam, South Africa. Part 1. River Zonation and the Benthic Fauna

Author: Chutter, FM Date: 1970 Vaal Dam is situated on the elevated plateau which forms the interior of South Africa and is a little less than 1500 m above the level. The source of the most of the streams and rivers flowing into the dam are about 2000 m above sea level, ... Read more
Impacts of afforestation on low flows: Paired catchment data revisited

Author: Blight, JJ ; Gush, Mark B ; Le Maitre, David C ; Jewitt, GPW Date: Sep 2005 Disruption of the hydrological regime caused by afforestation is well documented. Several sets of experimental catchments were set up in South Africa between 1935 and 1980 specifically to quantify such impacts. Data emanating from these ... Read more
Improving operational land surface model canopy evapotranspiration in Africa using a direct remote sensing approach

Author: Marshall, M ; Tu, K ; Funk, C ; Michaelsen, J ; Williams, P ; Williams, C ; Ardo, J ; Boucher, M ; Cappelaere, B ; De Grandcourt, A ; Nickless, A ; Nouvellon, Y ; Scholes, R ; Kutsch, W Date: Mar 2013 Climate change is expected to have the greatest impact on the world's economically poor. In the Sahel, a climatically sensitive region where rain-fed agriculture is the primary livelihood, expected decreases in water supply will increase food ... Read more
Initial hydrological modelling to assess impacts of different land uses on process hydrology in a small-scale semi-arid catchment in the Western Cape Province, South Africa

Author: Steudel, T ; De Clercq, W ; Bugan, Richard DH ; Jovanovic, Nebojsa ; Hardy, M ; Scheibler, F ; Helmschrot, J Date: Jun 2010 The main objective of the presented study was to develop a hydrological model to simulate and assess impacts of different land use types on basin hydrology. Read more
Invasive alien plants and water resources in South Africa: current understanding, predictive ability and research challenges

Author: Gorgens, AHM ; Van Wilgen, BW Date: Jan 2004 Predictions that invasive alien Plants would use significant amounts of water were a major factor in the establishment of South Africa's Working for Water programme, which aims to protect water resources by clearing these plants. The predictions ... Read more
Karoo biome: a preliminary sythesis. Part 1 - physical environment

Author: Cowling, RM ; Roux, PW ; Pieterse, AJH Date: 1986 This report, the first of three volumes, forms part of the Karoo Biome Project. One of the aims is to synthesize existing knowledge of the Karoo biome and so provide a foundation for further research in areas where it is considered necessary. ... Read more
Kuiseb environment: the development of a monitoring baseline. A report of the Committee for Terrestrial Ecosystems. National Programme for Environmental Sciences

Author: Huntley, BJ Date: 1985 The development of the world's largest open-cast uranium mine in the Namib Desert introduced rapidly increasing demands for water to the area in the early 1970's. In the absence of scientifically based information on the likely impact of water ... Read more
Linking ecosystem services and water resources: landscape-scale hydrology of the Little Karoo

Author: Le Maitre, David C ; Milton, SJ ; Jarmain, C ; Colvin, C ; Saayman, I ; Vlok, JHJ Date: Jul 2007 There is growing acknowledgement of the dependence of human society on ecosystem services and of the fact that service delivery is being compromised by human impacts on ecosystems. This paper describes the linkage between landscape-scale ... Read more
A method to quantify water quality change in data-limited estuaries

Author: Taljaard, Susan ; Lemley, DA ; Van Niekerk, Lara Date: Aug 2022 Situated at the land-sea interface, estuaries are susceptible to land- and sea-based sources of pollution. Despite growing scientific evidence of deterioration in water quality, quantitative methods to translate such information in support ... Read more
River-flow predictions for the South African mid-summer using a coupled general circulation model

Author: Olivier, C ; Landman, WA ; Beraki, Asmerom F Date: Sep 2013 There are limited sources of streamflow data available in South Africa. These include simulated streamflow for catchments across South Africa and measured river-flow at specific rivers around the country. Given that a number of studies has ... Read more
Spatial and temporal analysis of the nitrate concentrations in groundwater for South Africa

Author: Maherry, A ; Clarke, S ; Tredoux, G ; Engelbrecht, P Date: Nov 2009 The aims of this investigation was to create an updated view of the nitrate distribution for the country, to identify whether there are any gaps or significant changes in the distribution of nitrate concentration over the sampling record and ... Read more
Three centuries of managing introduced conifers in South Africa: benefits, impacts, changing perceptions and conflict resolution

Author: Van Wilgen, BW ; Richardson, DM Date: May 2012 Alien conifers, mainly pines, have been planted in South Africa for a range of purposes for over 300 years. Formal plantations cover 660 000 ha of the country, and invasive stands of varying density occur on a further 2.9 million ha. These ... Read more
