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, ... -
Assessment of satellite derived rainfall and its use in the ACRU hydrological model.
(2017)Many parts of southern Africa are considered water scarce regions. Therefore, sound management and decision making is important to achieve maximum usage with sustainability of the precious resource. Hydrological models are ... -
An assessment of satellite derived total evaporation data as a data source to the ACRU hydrological model.
(2014)Hydrological models and tools are often used as decision support systems to inform water resources management. The successful application of these systems is largely dependent on the quality of data being incorporated into ... -
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 ... -
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 ... -
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 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 of a geographic data model for hydrological modelling.
(2006)Hydrology is a multi-disciplinary science, and therefore derives data from diverse sources, with the data often of a spatio-temporal nature. A recent trend has been to combine these data with GIS, due to the data’s geographic ... -
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 ... -
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 ... -
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 ... -
Techniques for assessing the impacts of wetlands on hydrological responses under varying climatic conditions.
(2011)Wetlands are considered sensitive eco-tones that provide numerous goods and services, not only to the communities which are immediately dependent upon them, but also to the many downstream stakeholders who benefit from ... -
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 ...
