An adaptation of the SCS-ACRU hydrograph generating technique for application in Eritrea.
(2004)Many techniques have been developed over the years in first world countries for the estimation of flood hydrographs from small catchments for application in design, management and operations of water related issues. However, ... -
An analysis of baseflow recession in the Republic of South Africa.
(1997)Demands on the water resources of South Africa are ever increasing owing to population growth and increased development of urban, peri-urban and rural communities. Problems in terms of water quantity and quality are ... -
Approaches to modelling catchment-scale forest hydrology.
(2002)South African commercial plantations occupy an estimated 1.5 million hectares of the country and as the demands for timber products increase, this area is expected to increase. However, further expansion is limited, not ... -
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 ... -
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 ... -
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, ... -
A distributed sediment delivery ratio concept for sediment yield modelling.
(2004)Identifying areas of the hillslope that are most sensitive to soil erosion and contribute significantly to sediment yield is a primary concern in environmental protection and conservation. Therefore the ability to predict ... -
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 ... -
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 ... -
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. ... -
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 ... -
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 ... -
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 ... -
Towards improved parameter estimation in streamflow predictions using the ACRU model.
(2002)An unresolved problem in hydrology has been to establish relationships between catchment attributes and the flow characteristics of the stream. Such information is commonly sought to improve streamflow predictions, often ...
