The effect of long-term fire frequencies on soil hydraulic properties in semi-arid savannas in Kruger National Park.
(2013)Soils are vital in supporting healthy and functioning ecosystems. Thus when soils are degraded, important ecosystem services are affected. In African savannas where fire is a key driver controlling ecosystem composition ... -
The effect of spatial resolution in remote sensing estimates of total evaporation in the uMgeni catchment.
(2014)The estimation of total evaporation plays a vital role in water resources monitoring and management, especially in water-limited environments. In South Africa, the increasing water demand, due to population growth and ... -
The effect of the Lions River floodplain on downstream water quality.
(2015)Wetlands provide important ecosystem services, including the purification of water. The uMngeni catchment is an important basin providing water to the cities of Pietermaritzburg and Durban, South Africa’s second largest ... -
Effects of soil carbon and ambient carbon dioxide concentrations on hydrological processes: a modelling study.
(2020)Abstract available in PDF. -
Erosion dynamics at the catchment level : spatial and temporal variations of sediment mobilization, storage and delivery.
(2011)Soil material exported from river catchments by soil erosion is a key issue in environmental sustainability. Although soil erosion processes have been thoroughly investigated, their dynamics, specifically the continuity ... -
Estimation of catchment response time in medium to large catchment in South Africa.
Abstract and extended abstract available in the print copy. -
Estimation of the hydrological response to invasive alien plants in the upper Blyde River catchment.
(2003)The change in total evaporation through alteration of vegetative cover is a major influence on catchment hydrology. The transformation of grassland and scrub habitats to commercial tree plantations, as well as the uncontrolled ... -
Estimation of vapour pressure and solar radiation in South Africa.
(2004)Vapour pressure (interchangeably referred to as atmospheric humidity) and solar radiation data are, for different reasons, difficult data to obtain in South Africa. Relative humidity measuring instruments (from which vapour ... -
Estimation of water use efficiency of soybean (glycine max) for biodiesel production in KwaZulu-Natal.
(2020)Abstract available in pdf. -
Evaluating the effects of pre-packaging, packaging and varying storage environment treatments on the quality of avocados (Persea americana mill.)
(2013)Avocados are characterized as climacteric fruit and are vulnerable to rapid physiological deterioration. Maintaining avocado fruit quality requires proper integrated postharvest technologies. Thus, the primary aim of this ... -
Evaluation of a methodology to translate rainfall forecasts into runoff forecasts for South Africa.
(2002)South Africa experiences some of the lowest water resource system yields in the world as a result of the high regional variability of rainfall and runoff. Population growth and economic development are placing increasing ... -
The evaluation of pressure distribution and bulk density models for infield agriculture and forestry traffic.
(2006)There is evidence that soil compaction, through the use of mechanised equipment, causes detrimental effects to soil quality and reduces long-term productivity of soils. For economic reasons, farmers need to purchase larger, ... -
An evaluation of priority and fractional methods of water allocation in the Sand River catchment, South Africa.
(2014)The development and apportionment of water resources is a critical issue, both globally and locally in South Africa. This is particularly true in the development and allocation among states sharing watercourse systems. ... -
An evaluation of selected appropriate irrigation technologies for small-scale farmers.
(2001)South Africa lacks affordable irrigation technologies suited entirely to the needs of small-scale farmers. This is mainly due to the past emphasis on large, commercial farming technologies and the misunderstanding that ... -
The feasibility of desalination as an alternative means of water supply to Zinkwazi town.
(2005)Desalination of seawater is a widely used technology throughout the world, but is not commonly used in South Africa for domestic water supply. The reasons for this are varied, but very often are based on the assumption ... -
Flood routing in ungauged catchments using Muskingum methods.
(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 ... -
Ground and satellite-based assessment of hydrological responses to land cover change in the Kilombero River Basin, Tanzania.
(2013)Changes in land use and land cover are a global issue of concern, especially with regard to possible impacts on biophysical processes which affect the hydrological functioning of a system. Tanzania is no exception to ... -
A high resolution digital system for automated aerial surveying.
(2000)Resource managers frequently require moderate to high resolution imagery within short turnaround periods for use in a GIS-based management system. These spatial data can greatly enhance their ability to make timely, ... -
Hillslope experiments in the north east Cape region to measure and model subsurface flow processes.
(1997)Several hydrological studies claim that available water resources in a catchment are affected by large scale afforestation, especially where the regional rainfall is considered marginal for the support of silviculture. ...
