An assessment of water use by Acacia longifolia trees occurring within the hillslopes and riparian zone of the Heuningnes Catchment, Western Cape
Mkunyana, Yonela Princess (University of the Western Cape, 2018)The increasing expansion of Acacia longifolia trees along the riparian zones in South Africa demands an urgent intervention as the species is listed in the National Environmental Management: Biodiversity Act (2004). This ... -
A comparative assessment of the quantity and sources of water used by alien invasive prosopis spp and indigenous Acacia karroo in the Northern Cape Province
Ntshidi, Zanele (University of the Western Cape, 2015)Invasive alien plants (IAPs) are often reported to use more water than indigenous plants. Inaddition, IAPs have an ability to adapt to harsh environmental conditions and they tend to spread at rapid rates, thereby threatening ... -
Hydrological Characterisation of Wetlands: Understanding wetlands-catchment linkages
Mandlazi, Nompumelelo Pretty (University of the Western Cape, 2017)This study explores the hydrological processes of selected wetlands in four different catchments in South Africa (the Nuwejaars River in the Western Cape which has the Elandsdrift-Wiesdrift wetland; the Mohlapetsi river ... -
Improving estimation of precipitation and prediction of river flows in the Jonkershoek mountain catchment
Mbali, Siphumelelo (University of the Western Cape, 2016)Rainfall is the main input into the land phase of the hydrological cycle which greatly determines the available water resources. Accurate precipitation information is critical for mountain catchments as they are the main ... -
The influence of canopy cover and cultivar on rates of water use in apple orchards in the Western Cape Province, South Africa
Mobe, Nompumelelo Thelma (University of the Western Cape, 2020)Water availability and climate related issues are some of the greatest crop production risks to irrigated agriculture in arid regions. In South Africa, for example, the increasing frequency and severity of droughts related ... -
Influences of river flows on recruitment success of Fynbos riparian vegetation along selected high gradient streams in the Western Cape, South Africa
Magoba, Rozwivhona Faith (University of the Western Cape, 2014)Riparian vegetation occurs in two distinct zones, the wet bank and the dry bank. Knowledge on how the flow regime influences the zonal structure of riparian vegetation is required to mitigate the adverse effects of water ... -
The use of remote sensing for soil moisture estimation using downscaling and soil water balance modelling in Malmesbury and the Riebeek Valley
Möller, Jason John (University of the Western Cape, 2014)Soil moisture forms an integral part of the hydrological cycle and exerts considerable influence on hydrological processes at or near the earth’s surface. Knowledge of soil moisture is important for planning and decision-making ...
