Multispectral remote sensing of vegetation responses to groundwater variability in the greater floristic region of the Western Cape, South Africa
(University of Western Cape, 2021)
Groundwater dependent vegetation (GDV) communities are increasingly threatened by the transformation of the natural environment to different land use/land cover, over-exploitation of groundwater resources and the proliferation ...
Assessment of the water quality and quantity of the upper Liesbeek River dominated by Cannon Spring discharges: Ecological considerations for the Cannon Spring developmen
(University of Western Cape, 2021)
The ecology of spring fed rivers has been under-studied in South Africa. As a result, little is known or documented on the effects of seasonal variation of flows on the species diversity, distribution and abundance of ...
Using hydrogeochemistry and geophysical techniques to determine the extent of connectivity between Langerban road and Elandsfontein aquifer system, West Coast, South Africa
(University of Western Cape, 2020)
The heterogeneity in groundwater systems suggest that not all aquifers are connected in groundwater systems. This study is about the interaction between aquifers within groundwater system. Langebaan Road and Elandsfontein ...
Foraminiferal Biostratigraphy and Depositional Environment of the Early Cretaceous Drilled Succession in Durban Basin, East Coast, South Africa
(University of the Western Cape, 2020)
Durban Basin located on the eastern coast of South Africa has been a focus of interest for Petroleum Exploration for the last few decades. Only four exploratory wells have been drilled in this offshore basin without success. ...
Geochronology and geochemistry of the Postberg ignimbrites, Saldanha, Western Cape, South Africa
(University of the Western Cape, 2020)
The Saldania Belt in southern Africa, a product of the Pan-African Saldanian Orogeny, forms part of a system of Neoproterozoic mobile belts that border and weld older cratons on the African continent. It is a low-grade ...
Measurement and modelling of catchment erosion dynamics under different land cover types, Jonkershoek Catchment, Western Cape
(University of the Western Cape, 2020)
Several attempts have been made to assess the impact of post-fire soil erosion; however, erosion occurs as a result of the complex interplay between many factors, such as climate, land cover, soil and topography, making ...
Geomorphological controls on pool formation and pool persistence in non-perennial river systems
(University of the Western Cape, 2020)
Globally climate variability and anthropogenic effects are causing more perennial rivers to become non-perennial rivers. Non-perennial rivers are distinguished by their isolated pools which serve as refugia for aquatic ...
The petrogenesis of the intermediate to mafic rocks of the yzerfontein subsuite, and their relationship to-, and paragenesis of hydrothermal veining, cape granite suite, saldania belt, south africa
(University of Western Cape, 2020)
The 535 Ma post-orogenic Yzerfontein Pluton is a composite pluton that comprises rocks of mafic, intermediate and felsic compositions belonging to the shoshonitic series. The Yzerfontein Pluton forms part of the Cape Granite ...
Spatial modelling of invasive species distribution in water-limited environments using remotely sensed data and climatic scenarios in the Heuningnes catchment, South Africa
(University of Western Cape, 2020)
The occurrence and spread of Invasive Alien Plants (IAPs) is a threat to global water resources and natural ecosystems due to high water use rates. With the current climate change projections and their ability to survive ...
Investigating the role of groundwater - surface water connectivity in supporting non-perennial river systems, Sandveld, Western Cape, South Africa
(University of the Western Cape, 2021)
Non-perennial rivers are characterised by a discontinuous and variable hydrological flow regime which may retreat to form isolated pools along the watercourse during prolonged dry periods. The resulting spatio-temporal ...
