Hydrological connectivity in selected pristine catchments in the Kruger National Park.
(2014)The understanding of interactions between hydrological processes is essential, especially in water limited ecosystems in semi-arid environments. It is through this understanding that informed planning and management decisions ... -
Hydrological modelling applications for water resources management in the Mkomazi Catchment.
(2001)Predictions that water shortages will constrain economic growth in South Africa by 2025 have led to increased concerns among water resource managers that there is a need for comprehensive water management strategies. To ... -
The hydrosalinity module of ACRU agrohydrological modelling system (ACRUsalinity) : module development and evaluation.
(2003)Water is characterised by both its quantity (availability) and its quality. Salinity, which is one of the major water quality parameters limiting use of a wide range of land and water resources, refers to the total dissolved ... -
Impact of SOx and NOx deposition on the leaching behaviour of soils and water quality in the South African highveld.
(2014)Atmospheric emissions of sulphur and nitrogen oxides lead to the formation of acid rain, which, when deposited, can result in soil and water acidification. Cases of soil and water acidification have been reported in temperate ... -
The impacts of future urban growth on streamflow in the Mgeni catchment.
(2012)Natural vegetation has been converted to land uses, such as agriculture, commercial forestry and urban use, to meet increasing human demands for food, fuel and shelter. These land use changes modify the surface ... -
The impacts of woody invasive alien plants on stream hydrogeomorphology in small headwater streams of KwaZulu-Natal.
(2010)South Africa has a long history of problems with invasive alien species. In an assessment of alien invading plants and water resources in South Africa Versveld et al. (1998) estimated that Invasive Alien Plants (IAPs) in ... -
Improved estimation of catchment rainfall for continuous simulation modelling.
(2005)Long sequences of rainfall at fme spatial and temporal details are increasingly required, not only for hydrological studies, but also to provide inputs for models of crop growth, land fills, tailing dams, disposal of liquid ... -
In-field evaluation of irrigation system performance within the sugarcane industry of the south-east Lowveld in Zimbabwe.
(2007)The near collapse of the Zimbabwean sugarcane industry in 1991/1992 was concluded to be as a result of critical water shortages. This, combined with the uncertainty in the availability of water and a climate characterised ... -
The influence of scale and parent material on hillslope hydrological processes in Kruger National Park.
(2014)Semi-arid savannas are dynamic and complex systems controlled by fire, nutrient and water availability where water is the major driving force controlling the biological activity in these systems. Knowledge of hydrological ... -
Integrated water resources management studies in the Mbuluzi Catchment, Swaziland.
(2001)Problems in the water sector range from degradation and depletion of water resources as a result of the impacts of land based anthropogenic activities, to the impacts of natural hydrological disasters and floods, while ... -
Integrative policy instruments for implementing the National Water Act : a case study of the Mgeni Catchment.
(2013)South Africa experienced a paradigm shift with the introduction of the National Water Act in 1998 (NWA). Previously, water resource management was based on a centralized approach. Today, it is framed by the Integrated Water ... -
An investigation into sugarcane vehicle loading with respect to influences on overall transport efficiency.
(2011)The South African sugar industry ranks eleventh in size out of 200 sugar-producing countries; and continuous advancement is essential to ensure that this industry remains competitive. The transfer system from field to ... -
An investigation into the suspended sediment flux and dynamics of the Mgeni Estuary, Durban.
(2009)This dissertation focuses on both a hydrodynamic and geomorphological study of the Mgeni Estuary. Within the hydrodynamic study, the channel discharge, suspended sediment fluxes and estuary bed sediment characteristics and ... -
Investigation of the potential use of the root-zone storage concept in hydrological modelling under South African conditions.
(2019)Hydrological models are currently an accepted method used in determining the impacts of Streamflow reduction activities (SFRA) in South Africa. However, the limited availability of soils and rooting depth data create high ... -
Linkages between selected hydrological ecosystem services and land use changes, as indicated by hydrological responses : a case study on the Mpushini/Mkhondeni Catchments, South Africa.
(2014)Nature provides essential services to humans, including climate regulation, water provisioning and regulation. These so-called ecosystem services have economical, societal and environmental value. This research aims at ... -
Linking the hydrological, geomorphological and sociological aspects of wetlands in rural areas : a case study based in the Craigieburn wetland microcatchment in the Sand River catchment.
(2004)In many of the rural areas of South Africa local communities rely on wetland resources for daily living. For a symbiotic relationship to exist between these communities and the wetlands, the wetlands must be utilised in a ... -
A methodology for assessing irrigation practice in small scale community gardening.
(2001)The challenges facing small scale irrigation development in South Africa are varied and complex. This complexity is exacerbated by the many years of systematic neglect, in tandem with material and intellectual impoverishment ... -
Non point source pollution with specific reference to the Mkabela Catchment.
(2011)Non point source pollution (NPS) has long been the negated form of pollution within our natural systems. With an increase in the demand for quality crops and staple foods, there have been added pressures on water systems ... -
The potential impacts of up-scaled rainwater harvesting on ecosystem goods and services in the Potshini and Makanya catchments.
(2016)Water scarcity is fast becoming a global concern, with at least each continent facing water-related issues regarding quantity, quality and delivery. An estimated 8.8% of South Africans do not have access to potable water, ... -
The potential of micro-hydropower generation in the Inkomati River Catchment in Mozambique.
(2014)Hydropower is the leading source of renewable energy. It provides more than 97% of all electricity generated by renewable sources internationally. Small hydropower plants (SHPs) can be an alternative and a complement to ...
