An assessment of the water use of indigenous and introduced tree SPP. and varying land uses around Vasi Pan, Maputaland, KwaZulu-Natal.
(2017)Abstract available in PDF file. -
Balancing water for food and environment : hydrological determinants across scales in the Thukela River Basin.
(2008)In this study, geophysical measurements (Electrical Resistivity Tomography-ERT) and remote sensing techniques were applied in the Thukela river basin at various scales to complement the classical hydrometeorological ... -
Challenges in modelling hydrological responses to impacts and interactions of land use and climate change.
(2012)To meet society’s needs for water, food, fuel and fibre the natural land cover throughout the world has been extensively altered. These alterations have impacted on hydrological responses and thus on available water ... -
Characterisation of the hydrological processes and responses to rehabilitation of a headwater wetland of the Sand River, South Africa.
(2011)The erosion of headwater wetlands in the Sand River catchment, in the lowveld of north-eastern South Africa has led to a focus on their rehabilitation, both for livelihood security for those that use them for subsistence ... -
Comparison between satellite-based and cosmic ray probe soil moisture estimates : a case study in the Cathedral Peak catchment.
(2015)Abstract available in PDF file. -
Conceptualisations and applications of eco-hydrological indicators under conditions of climate change.
(2009)Anthropogenically-induced climate change has the potential to have serious implications on aquatic ecosystems and may ultimately affect the supply and quality of freshwater lakes and rivers throughout the world. As a class ... -
Deep row trenching of pit latrine and waste water treatment works sludge : water and nutrient fluxes in forest plantations.
(2012)The deep row trenching of ventilated improved pit-latrine (VIP) and waste water treatment works (WWTW) sludge is a unique alternative cost effective land application method that will prevent odour and health problems and ... -
Defining small catchment runoff responses using hillslope hydrological process observations.
(2000)The Umzimvubu catchment on the eastern coastal escarpment of South Africa is sensitive to anthropogenic influences,with commercial and subsistence agriculture, irrigation, domestic and rural settlements and forestry ... -
Definition of soil water dynamics by combining hydrometry and geophysics in a hillslope transect in the KNP.
(2006)The budgeting of water fluxes in the soil is an extremely complex problem, and is compounded by subsurface controls and environmental forces which modify the soil water dynamics. Of the controlling factors, the underlying ... -
Degradation of ecological infrastructure and its rehabilitation for improved water security.
(2018)Abstract available in PDF file. -
A description, quantification and characterization of hillslope hydrological processes in the Weatherley catchment, Eastern Cape Province, South Africa.
(2013)Advances in hillslope hydrology have been numerous in the past two decades. However many of these advances have been highly site specific in nature, without identifying any means of linking processes across different ... -
The design and testing of soil pressure sensors for in-field agricultural and forestry traffic.
(2005)River stage or flow rates are required for the design and evaluation of hydraulic structures. Most river reaches are ungauged and a methodology is needed to estimate the stages, or rates of flow, at specific locations in ... -
Design of a brush cutter blade and its integration into a semi mechanized sugarcane harvesting system.
(2007)Sugarcane is an important crop for South Africa. It provides employment and valuable foreign -
The design, construction and testing of a mobile essential oil distillation unit.
(2005)Steam distillation is the most widely accepted process for the large scale production of volatile essential oils from herbaceous material and is also regarded as the standard practice throughout the flavour and fragrance ... -
Detecting and assessing the impacts of outlier events and data availability on design rainfall and flood estimation in South Africa.
(2021)Accurate Design Rainfall Estimation (DRE) and Design Flood Estimation (DFE) require long periods of quality-controlled data for the planning, design, operation, and improved flood risk assessment of hydraulic structures. ... -
Detection and early warning of lightning and extreme storm events in KwaZulu-Natal, South Africa.
(2020)Abstract available in pdf. -
Detection of changes in temperature and streamflow parameters over Southern Africa.
(2005)It has become accepted that long-term global mean temperatures have increased over the twentieth century. However, whether or not climate change can be detected at a local or regional scale is still questionable. The ... -
Determining the capability of a vegetation cover to limit effluent leaching from a waste impoundment.
(2009)A final cover on a waste impoundment is the main physical barrier between the waste impoundment and the environment designed to protect against physical, chemical and biological factors isolating the waste from the atmospheric ... -
Developing a method to estimate the water use of South African natural vegetation using remote sensing.
(2016)The scarcity of water is a growing concern throughout the world. It is essential to accurately determine the quantity and quality of this valuable resource to aid in water resource planning and management. For this purpose ... -
Developing a real time hydraulic model and a decision support tool for the operation of the Orange River.
(2002)This thesis describes the development of a decision support tool to be used in the operation of Vanderkloof Dam on the Orange River so that the supply of water to the lower Orange River can be optimised. The decision support ...
