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 ... -
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 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 ... -
The development and assessment of a prototype water accounting system for South Africa using the ACRU2000 and MIKE BASIN models..
(2010)South African water management areas could find themselves without enough water for its users due to new methods of performing water allocation as stipulated in the National Water Act of 1998. A water accounting system ... -
Development and assessment of an automatic short furrow irrigation system.
(2010)Automated short furrow irrigation (ASFI) is a prototype irrigation system that has the potential to be robust and relatively low-cost, with highly effective and efficient water use. ASFI has low energy requirements because ... -
Development and assessment of an ensemble joint probability event based approach for design flood estimation in South Africa.
(2019)It has been reported that global climate change has impacted on the frequency as well as severity of flood events. Reliable flood estimates are required for managing and designing hydraulic structures, which is essential ... -
Development and assessment of rules to parameterise the ACRU model for design flood estimation.
(2015)Design Flood Estimation (DFE) is essential in the planning and design of hydraulic structures. Recent flooding in the country has highlighted the need to review the techniques used to estimate design floods in South Africa, ... -
The development and assessment of techniques for daily rainfall disaggregation in South Africa.
(2005)The temporal distribution of rainfall , viz. the distribution of rainfall intensity during a storm, is an important factor affecting the timing and magnitude of peak flow from a catchment and hence the flood-generating ... -
Development and evaluation of a sugarcane yield forecasting system.
(2000)There is a need in the South African sugar industry to investigate improved techniques for forecasting seasonal sugarcane yields. An accurate and timely forecast of seasonal cane yield is of great value to the industry, ...
